Amy earns $12.50 per hour at her work. She uses the equation shown to calculate the number of hours, she worked last week 12.5h = 312.5 how many hours did Amy work last week?

Amy worked 25 hours

Step-by-step explanation:

To first start off we have the equation 12.5h= 312.5

from here, we divide by 12.5 to have h by itself inorder to find how many hours she worked as h stands for hours.

Once you divide 312.5 by 12.5 you get h=25

Once again, the h stands for hours, so this means that Amy worked 25 hours, and that for one hour she earned 12.5 dollars.

If you want to find how much money she made for example in 5 hours, all you have to do is plug in the 5 for h and multiply it by 12.50 to get how much she earned in that certain amount of hours!

Hope this helps! If you have any questions, feel free to ask! :)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
