<u><em>Given:</em></u>

A barn is shaped like a rectangular prism with a triangular prism on top as shown.

<u><em>To Find:</em></u>

If one gallon of paint covers 232 square feet, how many gallons will it take to repaint the barn?

<u><em>Solve:</em></u>

<u><em></em></u>12\cdot38\div2\cdot2+84\cdot20+38\cdot20\cdot2

claudia bought 2 filing cabinets and 4 cupboards. A filing cabinet costs 3 times as much as a cupboard. She paid 800 altogether.
pickupchik [31]
If f = price of filing cabinet and c = price of cupboard we can make up the equation

2f + 4c =800

we also know that f = 3c, so can substitute that into equation

2(3c) +4c = 800

6c + 4c = 800

10c = 800

<u>c = 80</u>

<u>f = 240</u>

AURORKA [14]

Answer:

You could make a proportion, and divide or subtract the colors you like the least. Then, take the ones that you like the least away and put them in a separate place away from the others. For example: You have five colors, right? Ok, lets say your colors are blue, charcoal gray, yellow, green, and lilac.

Lets say your favorites are charcoal gray, lilac, and blue. (3/5)

So you put yellow and green to the side (2/5)

For example: You have 6 wallpaper patterns, right? Lets say your patters are flowers, dots, lines, stars, circles, and zigzags.

Lets say your favorites are flowers and stars. (2/6 or 1/3)

So you put dots, lines, circles, and zigzags to the side. (4/6 or 2/3)

Now, I want you to narrow your favorites down to what you favor more out of them. Now you have 3 paint colors, right? Your colors are charcoal gray, blue, and lilac. You need to narrow it down to 1 favorite. Lets say you choose the the lilac best.

Now you have 2 patterns, right? Your patterns are flowers and stars. You need to narrow it down to your favorite pattern. Lets say you choose the stars.

So, you will paint your wall lilac with the pattern of stars.
