tell whether the given number is a solution of each equation

Question

the distance in miles a family has traveled so far on their trip can be modeled by the equation y = 0.6x-75, where x is the number of minutes of driving today. how many minutes has the family been traveling today when they have been traveled 201 miles?

Answer 1

y = .6x - 75

201 = .6x -75

.6x = 201 + 75 = 276

x = 276/.6 = 460 minutes

= 460/60 = 7 hours and 40 minutes

y=.6x -75

y =.6(460) - 75 = 276 -75 = 201 miles
