1.) 28- all numbers listed are divisible by 28
2.) 15 (30/2, 45/3, and 75/5)

The gcf for the numbers 28, 56 and 84 is 28

Since

28: 1, 2, 4, 7, 14, 28

56: 1, 2, 4, 7, 8, 14, 28, 56

84: 1,2,3,4,6,7,12,14,21,28,42,84

Since the biggest number they all have is 14 so the gcf is 14.

The gcf for the numbers 30, 45, and 75 is 15

30: 1,2,3,5,6,10,15,30

45: 1,3,5,9,15,45

75: 1,3,5,15,25,75

Since the biggest number they all have is 15 so the gcf is 15.

Hope this helped

How to multiply and divide integers
Artyom0805 [142]

You multiply or divide integers just as you do whole numbers, except you must keep track of the signs. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer.

<span>
When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.</span>

<span>Positive x positive = positive 
Negative x negative = positive</span>

<span>When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.</span>

<span>Positive x negative = negative
Negative x positive = negative</span>

<span>When you divide two integers with the same sign, the result is always positive. Just divide the absolute values and make the answer positive.</span>

<span>Positive ÷ positive = positive
Negative ÷ negative = positive</span>

Solve for x.<br> - 30 – 5x - 1) + 7 = - 110
ololo11 [35]

Answer:

x =  \frac{86}{5}   = 17 \frac{1}{5}  = 17.2

Step-by-step explanation:

( - 30 - 5x - 1) + 7 =  - 110

( - 31 - 5x) + 7 =  - 110

- 31 - 5x + 7 =  - 110

- 24 - 5x =  - 110

- 5x =  - 110 + 24

- 5x =  - 86

\boxed{\green{x =  \frac{86}{5}   = 17 \frac{1}{5}  = 17.2}}
