Answer:

A. x=0

x+10x+9x

add x to 10x

subtract 11x to 9x

2x=0

divide Both sides by 2

The volume of the large cube is 125 cubic inches. The volume of the small cube is 27 inches. What is the difference between the
slega [8]

Answer:

<h3><em>2cm</em></h3>

Step-by-step explanation:

Step one:

given data

for the large cube

the volume= 125cm^3

we know that volume = l*l*l

volume=l^3

we want to find l, so we have to cube both sides

125=l^3

l=∛125

l=5cm

Step two:

given data

for the large cube

the volume= 27cm^3

we know that volume = l*l*l

volume=l^3

we want to find l, so we have to cube both sides

27=l^3

l=∛27

l=3cm

Consider the following formula y−p/2=e. Rearrange the formula to solve for "p":
Nezavi [6.7K]

Answer:

p = 2y - 2e

Step-by-step explanation:

Eliminate the fraction by multiplying all terms by 2:

2( y−p/2=e) = 2y - p = 2e

Now subtract 2e from both sides, obtaining:  2y - 2e = 0.

Finally, add p to both sides:  p = 2y - 2e
