Answer:
Step-by-step explanation:
2x-8 ≤ 14
1. Add 8 to both sides of the inequality sign to move the 8 from the left side to the right side.
2x ≤ 22
2. Divide both sides by 2 to get the x alone.
x ≤ 11
3. Make a number line from 8 to 13 (numbers can be changed), draw a circle above the number 11 and fill in the circle.
4. Now, make a line going from the circle to the left and draw an arrow at the end.
a coach bought three soccer balls on sale. they normally sell for $26 each. they were on sale for $7 off the original price. the total tax on the ball was $4 . the expression represents the total amount paid. Then explain how to use the order of operations to find the total amount the coach paid for the soccer balls.
Answer:
The coach paid $69 on the three soccer balls
Step-by-step explanation:
If the coach bought 3 soccer balls for 26$, minus the $7 on each, plus the $4 tax on each, the expression would be:
3 × (26 - 7 + 4)
We put the addition and subtraction in parentheses because of PEMDAS. PEMDAS say we must solve for whatever is in the parentheses first, then exponents (there are none in the expression), ans then multiplication. If those numbers were not in parentheses, the answer would look completely different as we would multiply before subtracting and adding. We must find the total amount each ball cost first:
26 - 7 + 4 = 23
Each ball cost $23
If the coach bought 3 balls for $23 each, we have to multiply the two numbers:
3 × $23
$69

Step-by-step explanation:
8n + 8 =-56 its a two step equating help please
Answer:
n = -8
Step-by-step explanation:
Original Equation:
8n + 8 = -56
Subtract 8 from boths sides.
8n = -64
Divide both sides by 8
n = -8
Hope this helped :)
Please consider Brainliest :)
Step-by-step explanation:
its -8
8n + 8 = 56
8n + 8 - 8 = 56 - 8
8=−64
8n/ 8 -= -64
8n / 8 = -64 / 8
simplified = n = - 8
n equals -8

Answer:
b-4.2<-7.5
Step-by-step explanation:
b-4.2<-7.5
this is because the number given as "b" minus 4.2 (as shown on the left) is less than (<) -7.5, so this inequality makes sense.
Answer:
b-4.2<-7.5
Step-by-step explanation:
helpppppppppppppppppppppppp
Answer:
By looking at the sides. BC is the same as HJ and 3 is half of 6. That goes with the rest of the equation
AC = GJ
AB = HG
So then the change in BCA is Double of GHJ
help on math angle question. ik its easy but I have no idea how math works :D
Answer:
71º is measure of angle A
19º is measure of angle B
Step-by-step explanation:
complementary angles are angles that equal to 90º
so let's add the terms (from angles A & B) and set them equal to 90º
3x+2 + x-4 = 90
4x -2 = 90
add 2 to both sides to get rid of the 2 on the left side and isolate our similar terms
4x = 92
divide both sides by 4
x=23
We're not done though, we must plug in our x value to Angle A terms and Angle B terms.
(3(23) + 2)º = measure of Angle A (solve for both of them)
(23-4)º = = measure of Angle B
3(23) + 2 =
3(23) = 69 (add the 2)
71º is measure of angle A
23-4 = 19º
19º is measure of angle B
double-check
71+19 = 90º
It works
Answer:
71º is measure of angle A
19º is measure of angle B

y is inversely proportional to x . When y = 3 , x = 20 Work out x when y = 12
Answer:
x = 5 when y = 12
Step-by-step explanation:
If y is inversely proportional to x, we can say that x1 : x2 = y2 : y1
The order of y2 and y1 respectively are interchanged as y is inversely proportional to x
Now let us simply substitute our known values, and solve for x2;
x1 : x2 = y2 : y1
20 : x2 = 12 : 3
20/x2 = 12/3
12(x2) = 3(20)
12(x2) = 60
x2 = 60/12 = 5
Find the slope. ( include whether positive or negative.)
Answer:
that is a negative slope
but dont know how to find the slope sorry
Step-by-step explanation:
[tex]\tt Step-by-step~explanation:[/tex]
Remember: To find the slope, we use the equation Rise/Run.
[tex]\tt Step~1:[/tex]
Let's find the rise first. Rise = How many units it goes up/down We can count down 6 units from the origin. Our rise is - 6.
[tex]\tt Step~2:[/tex]
To find the run. we count left/right. We could count 8 units. Our run is 8.
The slope is negative because it slopes downwards. If the slope is positive, then the line would be rising up.
[tex]\tt Step~3:[/tex]
To find the slope, we use the formula rise/run.
[tex]\tt \frac{-6}{8}=-\frac{3}{4}~or~ -0.75[/tex]
[tex]\large\boxed{\tt Our~final~answer:~m=-\frac{3}{4}~or~-0.75;~Negative~slope}[/tex]
Suppose y varies directly as x, and y = 21 when x = 3. Find x when y = 42.
Answer:
x = 24
Step-by-step explanation:
y₂ - y₁
42 - 21 = 21
x + 21
3 + 21 = 24
So when y increases by 21, so does x.
x = 24

Sharon has a cake she wants to share with her friends. If she gave 2/5 to Sam and 1/5 to mary. How much does she have left for herself?
Answer:
2/5 of the cake
Step-by-step explanation:
First, find how much she gave away:
2/5 + 1/5
= 3/5
Then, to find how much she has left, subtract 3/5 from 1
1 - 3/5
= 2/5
So, she has 2/5 of the cake left for herself

Why does the range of this function include negative values? What is the significance of the point where the graph crosses the horizontal axis
Answer:
Because the graph does not include any negative values for the range, the range is only nonnegative real numbers. Cubic function f(x)- x^3.
Ian bought a package of gummy bears that contains 4 cups. if he eats 2/3 cup everyday, how many days of candy does he have?
Answer:
6 days
Step-by-step explanation
2/3 cups x 3 days = 2 cups
2 cups x 2 cups = 4 cups
4 cups = 6 days
Answer:
6
Step-by-step explanation:
1) Get 4 and divide it by 2/3
2) To do this you put the inverse which is 4/1 x 3/2
3) Cross divide, then multiply.
4) (4/1 x 3/2) so 4/2 = 2 which is 2 (and whatever you do to one side, you have to do to the other side) so 2/2 is 1. Then 3/1 = 3 and 1/1 = 1 so it stays same. So now the equation becomes 2/1 x 3/1
5) This means the ones cancel out since in math ones don't have to be seen even though they are there.
6) 2 x 3 = 6
So you get 6
i’m confused on #3-5. Please help :)
Help with G and H plz
Answer: For G the answer is x=30, for H x is 30
Step-by-step explanation:
G. The square means 90 degrees and the equation would be 90+3x=180. Subtract 90 from both sides would give you 3x=90 and divide it by 3 would give you x=30
H. The two lines means that both sides are congruent and so 75x2=150 150+x=180 subtract 150 from both sides would give you x=30
What is the value of x? What is the value of y?
Answer:
x = 45/2y = 10Step-by-step explanation:
Both angles that have the "x" variable are the same and both angles that the "y" are the same since they are congruent meaning they are the same angle measure.
Solve for x.
6x - 5 = 8x - 50
~Add 5 to both sides
6x = 8x - 45
~Subtract 8 to both sides
-2x = -45
~Divide -2 to both sides
x = 45/2
Solve for y.
2y + 30 = 3y + 20
~Subtract 30 to both sides
2y = 3y - 10
~Subtract 3y to both sides
-y = -10
~Divide -1 to both sides
y = 10
Best of Luck!
