You are going on a field trip and need to choose where to go, The zoo charges a $100 fee plus $10 per student. The museum charges $200 plus $5 per student. How many students have to go on the trip to make the museum a better deal
Answer:
21 kids have to go on the trip to make the museum a better deal
Step-by-step explanation:
Zoo: y=10x+100
Museum: y=5x+200
10x+100=5x+200
5x=100
x=20
When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars

A student worked out an equation and below is his solution. is the answer correct? If not, where was the error and what is the correct answer?
-4(6-r)=12
-24-4R=12
-4R=36
R=-9
Answer:
His answer is wrong.
Step-by-step explanation:
-4(6-R)=12 <-- Since R is negative, -4 times -R results in a positive so, 4R.
-24+4R=12
+24 +24
--------------------
4R = 36
R= 9
The figures below show sketches of Earl's and Dylan's flower gardens. If the perimeter of each of their gardens is the same, what is the length and width of Earl's garden?
Answer:
[tex] length = 12 ft [/tex]
[tex] width = 8 ft [/tex]
Step-by-step explanation:
Earl's garden:
[tex] length = (x + 6) ft [/tex]
[tex] width = (x + 2) ft [/tex]
[tex] perimeter = 2(length) + 2(width) [/tex]
[tex] perimeter = 2(x + 6) + 2(x + 2) [/tex]
[tex] perimeter = 2x + 12 + 2x + 4 = (4x + 16) ft [/tex]
Dylan's garden:
[tex] length = (2x - 2) ft [/tex]
[tex] width = (x + 4) ft [/tex]
[tex] perimeter = 2(length) + 2(width) [/tex]
[tex] perimeter = 2(2x - 2) + 2(x + 4) [/tex]
[tex] perimeter = 4x - 4 + 2x + 8 = (6x + 4) ft [/tex]
Generate an equation to solve for the value of x.
Since the perimeters of both gardens are the same, therefore:
[tex] 6x + 4 = 4x + 16 [/tex]
Collect like terms
[tex] 6x - 4x = - 4 + 16 [/tex]
[tex] 2x = 12 [/tex]
Divide both sides by 2
[tex] x = 6 [/tex]
Earl's garden:
[tex] length = (x + 6) ft [/tex]
Plug in the value of x
[tex] length = 6 + 6 = 12 ft [/tex]
[tex] width = (x + 2) ft = 6 + 2 = 8 ft [/tex]
Answer:
l: 12ft
w: 8ft
Step-by-step explanation:
Solve [X + 8) = 5
With steps
Answer:
X=(-3)
Step-by-step explanation:
1.Subtract 8 from both sides of the equation.-(x+0)=5-8-the 0 is there because the 8 on the left side is canceled out.
2.5-8 is all you have to look at.-when you look at this you know that it will be negative because 8 is on the right of the minus sign and it is greater than 5.
3.Use a calculator or you fingers to find answer.-(4,3,2,1,0,-1,-2,-3)

Answer:
$0.1 /lb.
Step-by-step explanation:
First, divide 1.99 by 19. You get 0.1047368421. To round it to the nearest hundred, look to the number 3 points away from the decimal, which is number 4. Since it is not 5 or greater, we round it down, and it would round down to 0.1.

Answer:
4 1/9
Step-by-step explanation:
so if we make the fraction the same having 7 4/9 and 3 1/3
we would then make 1/3 into 3/9 (its the smae thing not simplified)
subtract 7-3=4
4-3=1
and then simplify the fraction

Brainiest goes to the first correct answer thanks
Answer:
20
Step-by-step explanation:
we can see that there are already answers for 2 which is six 6+6=12 now we can see that a triangle look the same as the six over the 8mm so that must be six so 6+6+6=18 now there is still s little section missing over the 8mm (the half triangle half square) is missing a section we can see that the perimeter is 8 and the area is 6 and 6+2=8 so that little area is 2 so 6+6+6+2=20

hey guys can you answer this one question real quick
Answer:
a. 1/5
b. (3, 3/5)
c. 1/5x = y
Step-by-step explanation:
Remember: (x, y)
0.5 = 1/2
(1/2, 1/10) = 1/10 ÷ 1/2 = 1/10 • 2 = 1/5, you can divide y/x = constant of proportionality. 1/10 ÷ 1/2.
1 2/5 = 7/5
(7, 7/5) = 7/5 ÷ 7 = 7/5 • 1/7 = 1/5, y/x = constant of proportionality. 7/5 ÷ 7.
a. 1/5 is the constant of proportionalityb. (3, 3/5) because 3/5 ÷ 3 or 3/5 • 1/3 = 1/5.c. 1/5x = yWhich exponent is missing for the given expression ?

solve.
5-(x-6)=-7+3(-x+2)
Answer:
x=-6
Step-by-step explanation:
For this equation, when we remove the parenthesis, we get 5-x+6=-7+-3x+6.
Then we simplify both sides of the equation, so we get 11-x=-1-3x. When we separate the numbers and variables, we get -12=-2x. -12/2 = -6.
Why does the base matter when simplifying negative exponents?
Answer:
A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, "x–2" (pronounced as "ecks to the minus two") just means "x2, but underneath, as in 1 x 2 \frac{1}{x^2} x21 ".

find the value of x. PLEASE HELP
I need to show my work
Thank you!!!!!!
===============================
Work Shown:
2x+108 = 180
2x+108-108 = 180-108
2x = 72
2x/2 = 72/2
x = 36
-------
Notes:
The reason 2x and 108 add to 180 is because they form a straight angleIn step 2 above, I subtracted 108 from both sidesIn the second to last step above, I divided both sides by 2.The general steps to solving any equation is to follow PEMDAS in reverse to isolate the variable.Given : There is a line . It is divided into two parts by another line such that it forms two angles on two sides of the angle which are 2x° and 108° .
To Find : The value of x .
Solution : Given that the two angles are 2x and 108° . So , we know that the measure of a straight line is 180° . So the sum of the two angles will be also equal to 180°. That is ;
[tex]\large\boxed{\red{\bf \angle 1 + \angle 2= 180^{\circ}}}[/tex]
Where [tex]\angle[/tex]1 and [tex]\angle[/tex]2 are two angles .⇒ 2x° + 108° = 180° .
⇒ 2x° = 180° - 108° .
⇒2x° = 72°.
⇒ x =[tex]\sf \dfrac{72}{2}[/tex]
⇒ x = 36° .
Hence the value of x is 36° .
