Jerome went on a hike. He climbed three-fourths of a mile in one-half of an hour. What was his hiking speed in miles per hour?

1 1/8

Step-by-step explanation:

3/4= 0.75

2/3 = 0.666666667 so on...

divide and you get 1.125 which is also written as 1 1/8

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
