I think that this is right, but I assumed that the ceiling has the same dimensions as the wall you would need 4 gallons for 2 coats.
Work:
20x8= 160 (square feet for 1 wall)
160x5=800 (i assumed there are 4 walls and 1 ceiling)
800x2=1600 (you need 2 coats)
1600/400=4 (each gallon includes 400 square feet)

Use substitution to solve the systems of equations. <br><br> y=x+1.75<br> 4x-2y=4
jolli1 [7]
Since y already equals something, x + 1.75, we can put its equivalent x + 1.75 in its place in the other equation. 
See the image for the rest of the solution steps.

A number is chosen at random from 1 to 25. Find the probability of selecting an even number or multiple of 13
sdas [7]

Probability helps us to know the chances of an event occurring. The probability of selecting an even number or multiple of 13 is 13/25.

<h3>What is Probability?</h3>

Probability helps us to know the chances of an event occurring.

\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}

Number of even numbers between 1 to 25 = 22

Number of multiple of 13 between 1 to 25 = 1

The probability of selecting an even number or multiple of 13 is,

Probability = (12+1)/25 = 13/25


Hence, The probability of selecting an even number or multiple of 13 is 13/25.
