S1: 7x - 4x - 2 = 6 OK
S2: 3x - 2 = 6 OK
S3: 3x - 2 + 2 = 6 WRONG, correct is 3x - 2 + 2 = 6 + 2

Answer: c. Step 3, because a number has been added only to one side of the equation.

Solve for x9(x + 1) = 25 + x
vaieri [72.5K]
When you expand the equation, you will have
9x + 9=25 + x
Next you have to collect like terms
+x will go over the equality sign to become -x. The same applies to +9
9x - x=23 - 9
9x minus x is 8x
8x=14
Divide both sides by 8
x=14/8
You will have 1 6/8
6 is the remainder while 1 is the number of times 8 divided 14.
In decimal, it will be 1.75
Hope that helped. Good luck

3(5+7) is the problem you are looking at. To figure it out, you can use properties. On the right side of the equals sign, it shows a property you can use to do the problem. In this case, they are distributing.

Eve plays basketball. She makes 5 free throws for every 3 free throws that she misses. If she missed 24 free throws at her last
juin [17]

Answer:

40

Step-by-step explanation:

Use the ratio 5:3 to answer the question.

5 = made free throws

3 = missed free throws

If she misses 24 free throws, compare the ratios 5:3 to x:24 (you are solving for x)

24 divided by 3 is 8, so multiply 5 by 8

You would get 40
