I am pretty sure that it is B
Answer:
7h=63 so a because she charges $7 per hour and earned a total of $63
Lets remember the property "alternative-interior angles" when we have parallels lines:
Given two paralles lines, the following is true:
In our question, we have:
We know that the angles J + P + K=180
So, the triangles have all the angles the same, so they are similar by angle-angle-angle, and they have one side congruent, AC=CD, so the triangles are congruents.
One crew is doing 1.3 miles daily, the other is doing 1.4 miles daily, so both together are doing 1.3 + 1.4 miles daily, namely 2.7 miles.
now, they are 6.75 miles apart, how many days will it be at a rate of 2.7 miles per day, that 6.75 miles will be done?

days
Y=20x+50
Y is the total cost and x is the number of hours
