Answer:

value of x=3

Step-by-step explanation:

Use the model to find the question and solve for x

-x  -x  -x represents -3x

1  1 1 1 1 1 represents 6

x  and x represents 2x

-1  -1  -1     -1     -1    -1  -1    -1    -1   represents -9

The equation becomes

-3x + 6 = 2x -9

Subtract 2x on both side

-5x +6 = -9

subtract 6 on both sides

-5x= -15

divide by -5

x= 3

The sum of eight times a number and fifteen is seven
asambeis [7]
8x+15=7

In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.

Solve for x: 6x – 8y = 12
Tcecarenko [31]

Hi there!


Since we have 2 variables in the given equation, and you only want to solve for one, the other will end up in your answer.


6x + 8y = 12


Step 1) Add 8y to both sides.


6x - 8y + 8y = 12 + 8y 6x = 8y + 12


Step 2) Divide both sides by 6.


\frac{6x}{6} =  \frac{8y + 12}{6}


x =  \frac{4}{3} y + 2


Final Answer -


x =  \frac{4}{3} y + 2


Hope this helps! :D

A children's pony ride at a zoo has ponies attached to a carousel pole in the center of a circle that the ponies walk around as
stepladder [879]
We simply need to solve for the circumference of the imaginary circle.

Given:
Diameter = 25 feet.

Circumference = 2 * radius * π             OR     Circumference = diameter * π

C = 25feet * 3.14
C = 78.50 feet

The pony will walk 78.50 feet to complete one trip around the circle.
