Three friends earned more than $200 washing cars. They paid their parents $28 for supplies and divided the rest of the money equally. Write an inequality to find possible amounts each friend earned. Identify what your variable represents.
Answer: 3x + 28 > 200
Step-by-step explanation:
[tex]$$Let $x$ be the amount each friend received. Since there are 3 friends, then $3 x$ is the amount of money they split evenly. The amount of money they split evenly was the amount left over after paying their parent's $\$ 28$. Therefore $3 x+28$ is the total amount they earned.[/tex]

[tex]\large\bold\red{\underline{Answer :-}}[/tex]
So, First of all The Question is to find out three consecutive Numbers .
First of all let's learn a little about Consecutive Numbers. So, Consecutive Numbers are the Numbers which follows each other. For example :- 1,2,3,4 are consecutive Numbers.
Let's start with Our Question :-
Let The First consecutive number be = xand second number be = x + 1Third number be = x + 2So,
[tex]:\pink\implies[/tex] [tex]\bold{{(x)^{2}}}[/tex] + [tex]\bold{{(x + 1)^{2}}}[/tex] + [tex]\bold{{(x + 2)^{2}}}[/tex] = [tex]\bold{{110}}[/tex]
[tex]:\pink\implies[/tex] [tex]\bold{{(x)^{2}}}[/tex] + [tex]\bold{{(x)^{2}}}[/tex] + [tex]\bold{{(1)^{2}}}[/tex]+ [tex]\bold{{2x}}[/tex] +[tex]\bold{{(x)^{2}}}[/tex] + [tex]\bold{{(4)}}[/tex]+ [tex]\bold{{(4x)}}[/tex] = [tex]\bold{{110}}[/tex]
[tex]:\pink\implies[/tex] [tex]\bold{{3x^{2}}}[/tex] + [tex]\large\bold{{6x}}[/tex] + [tex]\bold{{5}}[/tex] - [tex]\large\bold{{110}}[/tex] = [tex]\bold{{0}}[/tex]
[tex]:\pink\implies[/tex] [tex]\bold{{3x^{2}}}[/tex] + [tex]\bold{{6x}}[/tex] - [tex]\bold{{105}}[/tex] = [tex]\bold{{0}}[/tex]
By taking 3 Out as Common, we are left with the Quadratic Equation :—
[tex]:\pink\implies[/tex] [tex]\large\bold{{1x^{2}}}[/tex]+ [tex]\large\bold{{2x}}[/tex] - [tex]\large\bold{{35}}[/tex] = [tex]\large\bold{{0}}[/tex]
By Using Quadratic Formula,
x = -b ± √(b)^2— 4 × a × c / 2a
x = -2 ± √(2)^2— 4 × 1 × -35 / 2×1
x = -2 ± √144/2
[ As we know that "144" is square of 12 ]
x = -2 ± 12/2
Taking Positivex = -2+12/2x = 5Hence, x = +5
x +1 = 5+1 = +6
x+2 = 5+2 = +7
Taking Negative signx = -2-12/2x = -7Hence, x = -7
x+1 = -7+1 = -6
x+2 = -7+2 = -5
Hence, The Three consecutive Numbers are ±5,±6,±7.Answer:
± (5, 6, 7)Step-by-step explanation:
Let the three consecutive numbers be denoted as :
xx + 1x + 2Identity
(x + a)² = x² + 2ax + a²It is given that the sum of the squares of these numbers add up to 110.
(x)² + (x + 1)² + (x + 2)² = 110x² + x² + 2x + 1 + x² + 4x + 4 = 1103x² + 6x + 5 = 1103x² + 6x - 105 = 0x² + 2x - 35 = 0x² + 7x - 5x - 35 = 0x(x + 7) - 5(x + 7) = 0(x - 5)(x + 7) = 0x = 5 or x = -7Taking x = 5
x² = 5² = 25(x + 1)² = 6² = 36(x + 2)² = 7² = 49⇒ 25 + 36 + 49 = 110Taking x = -7
x² = (-7)² = 49(x + 1)² = (-6)² = 36(x + 1)² = (-5)² = 25⇒ 49 + 36 + 25 = 110Solution

8) Choose the correct linear system of inequalities for the graph given.
Answer:
To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equality sign. The graph of this equation is a line.
If the inequality is strict ( < or > ), graph a dashed line. If the inequality is not strict ( ≤ or ≥ ), graph a solid line.
Finally, pick one point that is not on either line ( (0,0) is usually the easiest) and decide whether these coordinates satisfy the inequality or not. If they do, shade the half-plane containing that point. If they don't, shade the other half-plane.
Graph each of the inequalities in the system in a similar way. The solution of the system of inequalities is the intersection region of all the solutions in the system.
Example 1:
Solve the system of inequalities by graphing:
y≤x−2y>−3x+5
First, graph the inequality y≤x−2 . The related equation is y=x−2 .
Since the inequality is ≤ , not a strict one, the border line is solid.
Graph the straight line.
Consider a point that is not on the line - say, (0,0) - and substitute in the inequality y≤x−2 .
0≤0−20≤−2
This is false. So, the solution does not contain the point (0,0) . Shade the lower half of the line.
Similarly, draw a dashed line for the related equation of the second inequality y>−3x+5 which has a strict inequality. The point (0,0) does not satisfy the inequality, so shade the half that does not contain the point (0,0) .
The solution of the system of inequalities is the intersection region of the solutions of the two inequalities.
Example 2:
Solve the system of inequalities by graphing:
2x+3y≥128x−4y>1x<4
Rewrite the first two inequalities with y alone on one side.
3y≥−2x+12y≥−23x+4−4y>−8x+1y<2x−14
Now, graph the inequality y≥−23x+4 . The related equation is y=−23x+4 .
Since the inequality is ≥ , not a strict one, the border line is solid.
Graph the straight line.
Consider a point that is not on the line - say, (0,0) - and substitute in the inequality.
0≥−23(0)+40≥4
This is false. So, the solution does not contain the point (0,0) . Shade upper half of the line.
Similarly, draw a dashed line of related equation of the second inequality y<2x−14 which has a strict inequality. The point (0,0) does not satisfy the inequality, so shade the half that does not contain the point (0,0) .
Draw a dashed vertical line x=4 which is the related equation of the third inequality.
Here point (0,0) satisfies the inequality, so shade the half that contains the point.
The solution of the system of inequalities is the intersection region of the solutions of the three inequalities.

1. 15.49 cm
2. 14.39 cm
3. 17.32 cm
4. 11.53 cm
5. 5 cm
Step-by-step explanation:
In the given problem, you can solve the unknown side of the triangle using either Pythagorean Theorem or SOA CAH TOA method. In Trigo, you can use the Pythagorean Theorem if the triangle has 90 degrees, or it is a right triangle.
In the given problem, the angle of the triangles are unknown, therefore to solve the unknown side of triangles, we will you use the SOA CAH TOA.
In this case, since the given side are b and c, we can use CAH (Cos Teta equals Adjacent over Hypotenuse), and TOA ( Tan Teta equals Opposite over Adjacent)
Lets provide the solution for the number, and the rest have the same solutions and process.
b= 17, c= 3, let u is the angle
Cosu= 17/23, to get the angle, use inverse cosine.
The result will be 42.34°, and to get the unknown side, use TOA
Tanu=a/17, a=17Tanu
It will give you 15.49 cm
In the number 2 and 5, it will be the same when you rotate the triangle.

SquaringThe usual way to solve these algebraically is to isolate radicals and square the equation until the radicals go away. Then solve the resulting polynomial. Here, that results in a quadratic with two solutions. One of those is extraneous, as is often the case when this solution method is used.
[tex]\sqrt{x+2}+1=\sqrt{3x+3}\qquad\text{given}\\\\(x+2)+2\sqrt{x+2}+1=3x+3\qquad\text{square both sides}\\\\2\sqrt{x+2}=(3x+3)-(x+3)=2x\qquad\text{isolate the root term}\\\\x+2=x^2\qquad\text{divide by 2, square both sides}\\\\x^2-x-2=0\qquad\text{write in standard form}\\\\(x-2)(x+1)=0\qquad\text{factor}[/tex]
The solutions to this equation are the values of x that make the factors zero: x=2 and x=-1. When we check these in the original equation, we find that x=-1 does not work. It is an extraneous solution.
x = -1: √(-1+2) +1 = √(3(-1)+3) ⇒ 1+1 = 0 . . . . not true
x = 2: √(2+2) +1 = √(3(2) +3) ⇒ 2 +1 = 3 . . . . true . . . x = 2 is the solution
__
SubstitutionAnother way to solve this is using substitution for one of the radicals. We choose ...
[tex]u=\sqrt{x+2}\qquad\text{requires $u\ge0$}\\\\u^2-2=x\qquad\text{solve for x}\\\\u+1=\sqrt{3(u^2-2)+3}\qquad\text{substitute for x in the original equation}\\\\(u+1)^2=3u^2-3\qquad\text{square both sides, simplify a little}\\\\2u^2-2u-4=0\qquad\text{subtract $(u+1)^2$}\\\\2(u-2)(u+1)=0\qquad\text{factor}[/tex]
Solutions to this equation are ...
u = 2, u = -1 . . . . . . the above restriction on u mean u=-1 is not a solution
The value of x is ...
x = u² -2 = 2² -2
x = 2 . . . . the solution to the equation
_____
Additional comment
Using substitution may be a little more work, as you have to solve for x in terms of the substituted variable. It still requires two squarings: one to find the value of x in terms of u, and another to eliminate the remaining radical. The advantage seems to be that the extraneous solution is made more obvious by the restriction on the value of u.

x=sqrt(160)
x=sqrt(16*10)
x=sqrt(16)*sqrt(10)
x=4*sqrt(10)
Step-by-step explanation:
The geometric mean of 8 and 20 in the simplest radical form is 2√10.
What is geometric mean?The Geometric Mean is a unique kind of average in which the numbers are multiplied together and then their square, cube, or other root is taken (for two numbers, three numbers, etc.).
To calculate the geometric mean of two numbers:
You would multiply the numbers together and take the square root of the result.
First, multiply 8 and 20.
That equals 160.
Then you take the square root of 160;
√160
= 12.65,
which doesn't result in a whole number.
So you factor 160 and removing perfect squares.

If there are 40 ants on the second part of the scale,
multiply 5 by 8 to get 40 because there are 5 ants for each row, and 8 rows total
and there are 10 ants visible on the first side of the scale, the second part of the scale would have the majority and there would be a big inbalance. To fix that, we could say there are 30 ants in the ant farm, because there are 10 ants on the scale. [tex]10 + 30 = 40[/tex], so that would make the scale balanced.
