Answer:
6
Step-by-step explanation:
1. re-write the given system:
cx+3y=c-3; => y= -cx/3 +(c-3)/3
12x+cy=c; => y= -12x/c+c/12
2. according the condition the rule for the parallel graphs is:
-c/3= -12/c
3. to calculate the unknown 'c':
c²=36; ⇔c=±6
Answer:
32ft^3
Step-by-step explanation:
All sides of a cube are in equal lengths. So using your equation 4s^3, you can substitute s for 2 because one side of a locker is 2 feet long.
4(x)^3
4(2)^3
4(2•2•2)
4(8)
=32
The total volume of all four lockers is 32 cubic feet.
Answer: $144
Step-by-step explanation:
8 tiles = $192
1 tile = $24
2 tiles = $48
192 - 48 = 144
she returned 2
8 - 2 = 6
6 tiles = $144
0.08x=7.50+0.05x
Subtract 0.05x from both sides.
0.03x=7.50
Divide both sides by 0.03.
