Answer 1
Answer: 1.) 4(x+3)
Find the GCF, Greatest Common Factor, of 4x and 12. 
4x=2*2*x
12=3*2*2
The greatest common factor is 4. Put this outside of the parentheses.             (You would multiply the 2*2)
Then, put the rest of the factors as a sum. (Only the factors on the same line.)
Solution: 4(x+3)

To check, distribute to see if it works.

4x+12

2.) 2(4r+7)
Find the GCF of 8r and 14
8r=2*2*2*r
14= -1*7*2
The greatest common factor is 2.                                                                 (There is only 1 two, so you would not multiply them.)
Then, put the rest of the factors as a sum. (Only the factors on the same line.)
Multiply the 2*2*r as one addend and the -1*7 as the other.
Solution: 2(4r-7)

To check, distribute to see if it works.

8r-14

Do you get it now?

3.) 5(x+7)
4.) 7(2x+1)
5.) Cannot be factored.

32x-15
Find the GCF of 32x and -15

32x: 2*2*2*2*2*x
-15: -1*5*3

Because there are no similar factors other than 1, it cannot be factored.

6.)  8(4x+3)
7.) 3(2x-3)
8.) 24(1x+2)
9.) 9(-2x+8)
10.) Cannot be factored
11.) 8(1x+3)
12.) 50(1x+5)

What is the best estimate for the product of 289 and 7

Answers

I would estimate it as (300 x 7) = 2100

Then I would subtract (11 x 7) + 77 from that to get the exact answer of 2023

~~~~~~~~~~
I didn't use a calculator or paper. The 'trick' is to notice that 289 = (300 - 11)
I was taught to round it up to the nearest ten, then multiply it like this,
289, rounded up is 290, then seperate the number, (200 + 90)

200 X 7 = 1400 (multiply the numeral, then add the zeros)
90 X 7 = 630 (repeat the same process)

1400 + 630 = 2030 (actual answer = 2023)

In the soccer games so far this season, Letty has had 15 goals in 20 attempts at a goal. What is the probability, expressed as a percent, that she will get a goal the next time she tries for one?A) 15%
B) 20%
C) 60%
D) 75%

Answers

20 is 1/5 of 100 so do 20x5=100 and 15x5=75


So there is a 75% chance she will make the goal
The answer would be D because 20 divided by 4 is 5 and 5 times 3 is 15 so 100 divided by 4 would be 25 and then that times 3 equals 75.
