You want to try and get rid of one of the variables ( x or y) so you would multiply the second equation by 2 which would make the x variable -2x which then when added to the first equation would eliminate the x variable.

Answer: c. Multiply the second equation by 2.

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.

answer

8/25

Step-by-step explanation:

so you would keep the first fraction (2/15) then you would change the symbol then you would flip the other fraction (5/12). then you would multiply 2*12=24 and 15*5=75. then you would simplifie it. it would be 8/25.
