Lillie Oconnell · Answer 1

r = 2.75

Step-by-step explanation:

1.25 + r = 4

Subtract 1.25 on both sides.

1.25 + r - 1.25 = 4 - 1.25

r = 4 - 1.25

r = 2.75

The solution to the equation is r = 2.75.

Tristen Garrett · Answer 2

r = 2.75

Step-by-step explanation:

In order to find r, you need to make it the subject:

so when you rearrange the equation it will be

r=4-1.25

= 2.75
