Rosa earns $12 per hour. In 7.5 hours, she will earn x dollars. Which is a valid proportion that can be used to solve the problem? x/12 = 1/7.5
1/12 = x/7.5
12/1 = x/7.5
12/1 = 7.5/x

A valid proportion that can be used to solve the problem is

Step-by-step explanation:

Given : Rosa earns $12 per hour.

we have to find a valid proportion that can be used to solve the problem if she works for 7.5 hours and earns x dollars.

Let denotes the fraction where x represents the amount she earns and b denotes the hours she works.

Thus, proportion becomes,

Solving for x, we get,

Cross multiply, we get,

Solving further , we get,

Thus, a valid proportion that can be used to solve the problem is

HOPE THIS HELPS!!!

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.
