Answer: 1728 dollars</h3>
==========================================================
Explanation:
1 yard = 3 feet
We'll divide by 3 to convert from feet to yards
- 27 feet = 27/3 = 9 yards
- 18 feet = 18/3 = 6 yards
The basement is 9*6 = 54 square yards in floor area.
At $32 per square yard, the total cost to carpet the floor is 32*54 = 1728 dollars.
3x*5x-2=4-2x*1
15x-2=4-2x
13x=2
x=6.5
Answer:
$17.85
Step-by-step explanation:
Let the dollar amount per shirt be represented by s.
Let the dollar amount per pants be represented by p.
You have the following system:
3s+2p=104.81
2s+1p=61.33
If I multiply the bottom equation by -2, I can set the system up for elimination since the equations are already and the same form and I will have 2p and -2p in the same column there. 2p+(-2p)=0
Multiplying equation 2 by -2:
3s+2p=104.81
-4s-2p=-122.66
-----------------------Add the equations:
-1s =-17.85
Multiply both sides by -1:
s=17.85
So one shirt cost $17.85
