The volume of a pyramid is one-third the volume of a prism.
The formula for the volume of a pyramid is V = 1/3Bh
Answer:
x = 9/2
Step-by-step explanation:
2(6-x)=3
Distribute
2*6 -2*x = 3
12 -2x =3
Subtract 12 from each side
12-12-2x = 3-12
-2x= -9
Divide each side by -2
-2x/-2 = -9/-2
x = 9/2
Answer:
$40
Step-by-step explanation:
x is the original price of the gift
(10% of x) is the value of the discount
(10% of x) = 10/100 . x = 0.1 x
0.1 x is the value of the discount
x - (10% of x) is what was paid, after the discount
x - 0.1 x = 0.9 x
0.9 x is what was paid
4 children paid $9/each
4 times $9 = $36
$36 is the total amount that was paid by the children
$36 = 0.9 x
$36 / 0.9 = x
x = $36 / 0.9 = 360 / 9
x = 40
