Question

What do you do to both sides to
r? What is r? 3/8 r = 6 HELP ME

Answer 1

r = 16

Explanation:

`(3)/(8)r = 6 \\\\`

Multiply both sides by 8

`8*(3)/(8)r = 6*8\\\\3r = 48\\`

Divide both side by 3

`(3)/(3)r=(48)/(3)\\\\r = 16`

OR

Multiply both side by (8/3)

`(8)/(3)*(3)/(8)r=6*(8)/(3)\\\\r = 2*8\\\\r = 16`

write an equation to represent the information in this problem. Jerel runs five days each week. on each of 4 days, he runs 2.3 km. if jerel runs a total of 14km, how many kilometers does he run on the fifth day?

Let x be the distance run on the fifth day

Total distance run on all the four days = 2.3 * 4 = 9.2 km

Required equation : x + 9.2 = 14

x = 14 - 9.2

x = 4.8 km
