Answer: B - 8

Step-by-step explanation:

If we plug in 8 into p, we have the following equation:

30 = 5(8) - 10

There are two ways we can simplify this:

Option 1:

Add ten to both sides to neutralize the -10.

We will now have:

40 = 5(8)

Then you can multiply.

40 = 40. The equation is true.

Option 2:

Multiply 5 by 8.

30 = 40 - 10

Then subtract.

30 = 30. The equation is true.

Hey there!

30 = 5p - 10

5p - 10 = 30

ADD 10 to BOTH SIDES

5p - 10 + 10 = 30 + 10

CANCEL out: -10 + 10 because that gives you 0

KEEP: 30 + 10 because it helps solve for the p-value

30 + 10 = 40

NEW EQUATION: 5p = 40

DIVIDE 5 to BOTH SIDES

5p/5 = 40/5

CANCEL out: 5/5 because that gives you 1

KEEP: 40/5 because it gives you the answer of p

NEW “temporary” EQUATION: p = 40/5 or 40/5 = p

SIMPLIFY ABOVE AND YOU HAVE YOUR ANSWER TO THE P-VALUE.

IF YOU SIMPLIFIED THE CORRECT WAY YOU SHOULD'VE CAME UP WITH “8”

Therefore, your answer is: Option B. p = 8

Good luck on your assignment and enjoy your day!
