I have one selected but I don't know if it's right? can someone tell me the right answer so I can understand what I did wrong?
kozerog [31]

Answer:

It's y = 3

Step-by-step explanation:

Reason why it's not x = 3 is because x is on the left to right or horizontal plane, therefore it would be y because y is on the vertical axis. If using x, it would be a vertical line on x while using y would create a horizontal line.

A gallon of paint can cover 400 square feet. To the nearest half gallon, find how much paint will be needed to paint two coats o
morpeh [17]
You'll need to calculate the surface area to be painted.  The room has two ends, 2 sides and 1 ceiling.  The area of the ceiling is 18*20.  The area of the two ends of the room is 2(8*18).  The area of the two long walls is 2(8*20)

Add these areas together:  18*20 + 2*8*18 + 2*8*20, or 968.

That's 968 square feet.  Since each can contains enough paint for 400 square feet of coverage, divide 968 by 400:

968
----- = 2.42.  This means having to purchase 2.5              (gallons)
400              This answer is accurate to the nearest 0.5.
