Last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x
represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail.
if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail?
o x + y = 90
5x – 10y = 90
o 90 – 10y = 5x
o 90 + 10y = 5x

b and c

step-by-step explanation:

7

step-by-step explanation:

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
