36 minutes
Step-by-step explanation:
It takes 45 mins to deliver paper on her route.
Let X be the amount of time it takes the brother to complete the route.
The brother works at the rate of 1/x route per min
The girl works at the at the rate of 1/45 route per min
Girl and brother working together works at rate of 1/20 route per min
1/x + 1/45 = 1/20
Multiply through by 180x
180 + 4x = 9x
4x - 9x = -180
-5x = -180
x = -180 / -5
x = 36 mins.
It takes the brother 36 minutes to complete route alone.
To convert an equation to slope intercept form, you have to isolate the y variable.
-2x + 3y = 15
Add 2x to both sides.
3y = 2x + 15
Divide all terms by 3.
<h3>y = 1.5x + 5 is the original equation in slope-intercept form.</h3>
