If you wanted to mix pure methane with water and end up with 70 gallons of 20% methane, how many gallons of each should you use? You should use gallons of water and gallons of methane > Next Question

You want 40% of 140 gallons to be methane,

so 60% of 140 gallons is water

methane:  0.4(140) = 56 gallons

water:  0.6(140)  = 84 gallons

Step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
