The correct equation is x=3 because there is no (Y) in the rise over run (y/x) meaning the starting point up and down the point on the (X)
Answer:
She need <u>96 square feet</u> carpet to cover the room.
Step-by-step explanation:
Given:
Tina covers the floor of a room with carpeting. She uses carpet squares that measure one foot on each side.
Now, to find carpet squares does she need to cover a room that 8 feet wide by 12 feet long.
So, the dimensions of room are:
Length = 12 feet.
Width = 8 feet.

<u><em>Area of room = Length × width</em></u>


Therefore, she need 96 square feet carpet to cover the room.
Answer:
Step-by-step explanation:
n and d are the number of nickels and dimes, respectively.
"there are 20 coins"
n+d = 20
d = 20-n
"total value is $1.40"
0.05n + 0.10d = 1.40
0.05n + 0.10(20-n) = 1.40
-0.05n + 2 = 1.40
0.05n = 0.6
n = 12
d = 20-m = 8
