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

x= 47

Step-by-step 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

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
