A race car is traveling at a constant speed of 150 miles per hour. How many feet does it travel in 5seconds
alukav5142 [94]

Answer:

  1100 ft

Step-by-step explanation:

1 mile per hour is equivalent to 22 ft in 15 seconds, so we can convert the speed to distance using ...

  distance = speed × time

  distance = (150 mi/h) (22/15 ft/s)/(1 mi/h) (5 s) = (150·22·5)/15 ft = 1100 ft

The car travels 1100 feet in 5 seconds.

Solve 3x + 8 = x + 16
Nutka1998 [239]

Answer:

x = 4

Step-by-step explanation:

Move all "x"s to one side of the equation:

(3x + 8) - x = (x + 16) - x

2x + 8 = 16

Subtract 8 from both sides so that all the numbers are on one side of the equation:

(2x + 8) - 8 = (16) - 8

2x = 8

Divide both sides of the equation by 2:

x = 4
