The 'x' coordinate of the midpoint is the average of the 'x'
(4x - 8) = 80/2
4x - 8 = 40
4x = 48
x = 12
answer
x = 12
If Liza takes 120 steps, then the number of steps taken by Pete will be 72.
<h3>What are a ratio and a proportion?</h3>
A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A percentage is a mathematical expression in which two things are equal.
Pete, Lulu, and Liza are walking in the Boston downtown. Each time Pete takes 4 steps, Lulu takes 3 steps. Each time Lulu takes 5 steps, Liza takes 4 steps.
Then the relation between is given as
4 Pete → 4 Lulu
5 Lulu → 4 Liza
Then we have

If Liza takes 120 steps, then the number of the step taken by Pete will be

Answer:
DE = 1.2ft
Step-by-step explanation:
It's actually a lot easier for someone to just draw a diagram. I recommend it in the future!
This is a right-angle triangle, so I'm guessing it's Sohcahtoa.
cos23° = DE/1.3
DE = 1.3cos 23°
DE = 1.1966...
Rounded:
DE = 1.2
