12 dolls cost $60. what will 72 dolls cost?

Hi there!

To get the answer of this math problem is pretty simple: I can prove it to you! :)

First, you find out the price of 1 doll.

How?

Divide 12 by 60 to see what you get.

12 ÷ 60 = 5$.

Now, to see how much money 72 dolls cost, you can add up 5 about 72 times, or even better, multiply.

5 × 72 = 360$. This is a lot of money for the 72 dolls!

Our final answer is 360$.

Hope this helps! :D

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'.
