<h3><u>The unknown number is equal to 4.</u></h3>

8x - 27 = 5

Add 27 to both sides.

8x = 32

Divide both sides by 8

x = 4

Multiply both sides by 3x

2 = 6.3x

2 = 18x

x = 2/18

What are the common factors for 88 and 24
Zinaida [17]
To find the common factors between two numbers, you must first break the numbers down into factors, and then find all common factors.
Let's break down 88.

88: 2 x 44, 4 x 22, 8 x 11.

Now let's break down 24.

24: 2 x 12, 3 x 8, 4 x 6.

Now that we've factored both numbers, let's select all the common factors.

Common factors:
1, 2, 4, 8.

I hope this helps!

M is between points C and Q. CM=17 and CQ=21. What is MQ?
katrin2010 [14]
Sometimes it helps to draw it out...

     (17)
C_______M_________Q
|___________________|
             21

therefore, CM + MQ = CQ
17 + MQ = 21
MQ = 21 - 17
MQ = 4 <===
