5x - 5 = 50
just to clarify is it
11

Add 5 to both sides

5x = 50 + 5

Simplify 50 + 5 to 55

5x = 55

Divide both sides by 5

x = 55/5

Simplify 55/5 to 11

x = 11

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
