Answer:

Step-by-step explanation:

2.5x+8y=200

We want to get this in slope intercept form so we will solve for y

Subtract 2.5x from each side

2.5x-2.5x+8y=-2.5x +200

8y = -2.5x +200

Now divide by 8 on both sides

8y/8 = -2.5x/8 + 200/8

y = -.3125x +25

The y intercept is 25, so plot a point there

-.3125 = -5/16

Go down 5 and to the right 16 and plot a point. Connect the two points to make a line.

Answer:

Step-by-step explanation:

There were 9 other people there. First you would subtract how much marcus paid from the total (134.03-20.45=113.58). After that you just divide the remaining cost with 12.62 (113.58/12.62=9)

Denise is using a ladder to clean the outside of her second story windows. The ladder she is using is 24 feet long, and she puts

agasfer [191]

In order to solve this you have to use the pythagorean’s theorem, which is a^2+b^2=c^2. from the problem you can find out you have a=13ft and c=24ft. c is your hypotenuse. you then solve and you get b=20.17ft. you can check to make sure the answer is right, but that is how you solve it. And the ladder would reach 20.17ft.
