John has finished 20% of an art project that taken 3 hours if he Continues to work at the same rate how many hours will it take

15 hours to do the entire project

Step-by-step explanation:

20% is the same as 1/5.

"percent" means "per 100", so 20% means 20/100 which reduces to 1/5.

20% of an art project took 3 hours. That means that 1/5 of the art project took 3 hours. The entire project then takes 5 times as much time.

5 * 3 hours = 15 hours

It takes 15 hours to do the entire project.

15 - 3 = 12

It takes 12 more hours after 20% was done.

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
