Last week Jovanna ran 30 miles more than Rachel. Jovanna ran 47 miles. How many miles did
Rachel run?
A. 30 + x = 47

B. 30 - x = 47

C. 47 + x = 30

D. 47x = 30

A

Step-by-step explanation:

if rachel is 'x' and jovanna ran 30 more miles than her, then jovanna ran 30+x miles

we know that jovanna ran 47 miles so we set both values equal to each other

30 + x = 47

which is option A :))

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

they would have to work 32 hours.
