Answer:

x = 15

Step-by-step explanation:

Given

3(x - 8) + 4 - 2x = - 5 ← distribute and simplify left side

3x - 24 + 4 - 2x = - 5

x - 20 = - 5 ( add 20 to both sides )

x = 15

Answer 2

Answer:

x = 15

Explicación paso a paso:

Dado

3 (x - 8) + 4 - 2x = - 5 ← distribuir y simplificar el lado izquierdo

3x - 24 + 4 - 2x = - 5

x - 20 = - 5 (suma 20 a ambos lados)

x = 15

What is the value of x in the equation Negative 6 x = 5 x + 22?

Answers

Answer:

Hi there!

Your answer is:

x= -2

Step-by-step explanation:

-6x = 5x +22

Subtract 5x from both sides

-6x-5x = 22

Simplify

-11x = 22

Divide both sides by -11

x= 22/-11

Simplify

x= -2

Hope this helps!

Answer:

x=-2

Step-by-step explanation:

The equation here is -6x=5x+22

First we can move the term 5x to the left side by subtracting 5x from both sides of the equation giving us

-11x=22

From here we need to divide both sides of the equation by -11 to isolate the variable so we get

-11x/-11=22/-11

This then is simplified to

x=-2

Which is the answer.

the dry cleaning fee for 3 pairs of pants is 18 .how much will they dry cleaner charge for 11 pairs of pants ??

Answers

Answer would be 66.

To find the cost of the dry cleaning per pair of pants, you divide 18 by 3.

The answer to that is 6, so you multiply the number of pants you're planning to dry clean, which is 11. So:

6 x 11 = 66

Well first off you need to find how much it cost for one pair of pants. So, you will do

18 divided by 3

since 18 is the price all together for 3 and there’s 3 pairs of pants. It’ll cost 6 for one pair of pants, so now you can do

6 multiplied by 11

You will then get 66 and it cost 66 dollars for 11 pairs of pants. Hopefully that makes sense :)

1/2 divided by 3/4= 1/a multiplied by b/c = d/e

Answers

Answer:

$50 a month

Step-by-step explanation:

X= amount per month

(725-125) /12= x

600/12=x

50=x

Answer:

725= 125+ 12x    (equation)    50$ (answer).  x (variable)

Step-by-step explanation:

725  = 125+ 12x

-125.    -125

600 = 12x

12x = 600

divide 12, both sides

x = 50

So $50 dollars each month.

There's a 12 because there's 12 months in a year and it's asking for "each month"

x is the variable and it stands for how much money $ new members pay each month.
