Question

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

Answer 1

Answer:

r = 16

Step-by-step explanation:

$\frac{3}{8}r = 6$

Multiply both sides by 8

$8*\frac{3}{8}r = 6*8\\\\3r = 48$

Divide both side by 3

$\frac{3}{3}r=\frac{48}{3}\\\\r = 16$

OR

Multiply both side by (8/3)

$\frac{8}{3}*\frac{3}{8}r=6*\frac{8}{3}\\\\r = 2*8\\\\r = 16$

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
