Question

This month, Dori biked 11 times as many miles as Carly. Together they like the total of 156 miles. How many miles to Dori bike last month

Answer 1

The answer is 14 u have to divide 156÷11=14

Answer 2

d = 11c
d + c = 156

11c + c = 156
12c = 156
c = 156/12
c = 13

d = 11c
d = 11(13)
d = 143 <== she biked 143 miles
