Step-by-step explanation:
You must multiply both numbers by 2 so that you can calculate how far she will go in 1 hr. 1/4*2=1/2
Z = 12.
5z + 8 = 4z + 20
z + 8 = 20
z =12
Answer:
Step-by-step explanation:
Given
Required

Step-by-step explanation:
Pythagorean Theorem
7² + 8² = x²
49 + 64 = x²
113 = x²
x = √113 or 10.63
Distance Formula
√(-4 - 4)² + (4 - -3)²
= √8² + 7²
= √113 or 10.63
