3(x+8)=42.

We move all terms to the left:

3(x+8)-(42.)=0

We add all the numbers together, and all the variables

3(x+8)-42=0

We multiply parentheses

3x+24-42=0

We add all the numbers together, and all the variables

3x-18=0

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

3x=18

x=18/3

x=6

<h2>Answer: x=6</h2>

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x+8)=42

(3)(x)+(3)(8)=42 (Distribute)

3x+24=42

Step 2: Subtract 24 from both sides.

3x+24−24 = 42−24

3x=18

Step 3: Divide both sides by 3.

\frac{3x}{3} =\frac{18}{3}

Therefore, the correct answer is x=6

* Hopefully this helps:) Mark me the brainliest:)!!

Use each digits 2,3,7,8 to make numbers FROM 20,21,22 SO ON ALL THE WAY TO 50 FOR EXAMPLE 2+3+7+8=20
Ahat [919]
2+3+7+8=20 

2 x 3+7+ 8= 21


2 x 7 + 3+ 8= 25

8 x 2 + 7 + 3= 26

3 x 7 +8 - 2= 27

8 x 3 + 7 - 2= 29

8 x 7 ÷ 2 + 3= 31

7 x 2 x 3 -8 = 34
 

There is a couple, but i am not doing all of them
 I hope this helps anyway :).

KatRina [158]

Answer:

30

Step-by-step explanation:

Work backwards:

  • 6 is 3/5 of a number, and that number is 10
  • 10 is 1/3 of a number, and that number is 30

Check your work:

  • 2/3 of 30=20 toy to Sarah
  • 30-20=10 toys left
  • 2/5 of 10=4 toys to Ryan
  • 10-4=6 toys left

From a group of 13 women and ​12 men, a researcher wants to randomly select 8 women and 8 men for a study. In how many ways can
Fantom [35]

The total number of ways the study can be selected is: 637065

Given,

Total number of women in a group= 13

Total number of men in a group = 12

Number of women chosen = 8

Number of men chosen = 8

∴ the total number of ways the study group can be selected = 13C₈ and 12C₈.

This in the form of combination factor = nCr

                                                     ∴ nCr = n!/(n₋r)! r!

13C₈ = 13!/(13 ₋ 8)! 8!

        = 13!/5!.8!

        = 1287

12C₈ = 12!/(12₋8)! 8!

        = 12!/5! 8!

        = 495

Now multiply both the combinations of men and women

= 1287 × 495

= 637065

Hence the total number of ways the study group is selected is 637065
