Answer:
Step-by-step explanation:
-x-2y+4z=-14
x=-2y+4z+14
2x+2y+2z=-6
2x=-2y-2z-6
x= -y-z-3
-x-6z=-3
x=3-6z
Answer:
approximately 3.16 repeated
Step-by-step explanation:
Use the given information to write an equation, then solve it.
$1600 = (1 + 1 + 1/2)×(monthly rent) . . . . relationship given in the problem statement
$1600/2.5 = monthly rent = $640 . . . . divide by the coefficient of monthly rent
Step-by-step explanation:
I think
volume = area of the base × the height
[1/2×(2+2)×6] × 8
= 1/2×24×8
= 24×4
= 96 ft³
74% means 0.74
"of" means "times"
So, 128 = 0.74 times (the number)
Divide each side of this equation by 0.74 :
128/0.74 = the number
<em>172.973</em> (rounded) = the number
