Need bernard typically runs x km/hour. while he was sick, he only ran 41.5 km/hour. what equation represents that the difference in his speeds is 13.5 km/hour? x – 41.5 = 13.5 41.5 + x = 13.5 13.5 – x = 41.5 13.5 – 41.5 = x

The answer is

Step-by-step explanation:

To find the correct equation we have to separate each one of the terms:

Typically runs = x km/hour

Sick run = 41.5 km/hour

Difference in speed = 13.5 km/hour

This is a case of a subtract, so we have to subtract the typically run and the sick run and the answer will be the difference in speed, this is=

In the terms of the answers, we have:

The answer is

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

i think it is 18
