Hey there! :)
Answer: x = 9.4
Step-by-step explanation : How do we know this? Well, let's first rewrite our question.
(-16.1) · 9.4 · (-7.2) = x · (-7.2) · (-16.1)
Let's multiply everything out.
(-16.1 · 9.4 · -7.2) = (x · -7.2 · -16.1)
Simplify.
1089.648 = 115.92x
Our goal is to isolate x, so we should divide both sides by 115.921089.648 ÷ 115.92 = 115.92x ÷ 115.92
Simplify.
9.4 = x
So, our final answer is x = 9.4

These rates are not in proportion. Juan walked faster.
Explanation:
First, we want to make these ratios to have the same denominator so we can compare the numerators. To do this, do 3x5 and 8x5 to get 40:15. Then, we do 5x3 and 14x3 to get 42:15. Now we can just compare the numbers 40 and 42, and since 42 < 40, we know Juan walked faster.
