Question

Kirsten and Molly are on a 3-day bike ride. The entire route is 156 miles. On the first day, they biked 64 miles. On the second day, they biked 45 miles. How many miles do they have left to bike on the third day? A. 49 miles B. 47 miles C. 50 miles D. 48 miles

Answer 1

all you have to do is add 64 + 45 which equals 109 then subtract from fifty which is b 47

Answer 2

x= 47

Explanation:

They are biking 3 days

64+45+x where x is the distance on the third day

The total is 156

64+45+x = 156

Combine like terms

109 +x = 156

subtract 109 from each side

109+x-109 = 156-109

x =47
