5
3
2

Answer 1

@mathmale

Answer 2

do you know what the distributive property is

Answer 3

sorta

Answer 4

im going to try and solve it and you tell me if i did it right

Answer 5

okay

Answer 6

i got 5?

Answer 7

idk

Answer 8

sorry trying to multitask 2 questions and my own homework

Answer 9

sorry i got 2

Answer 10

is that right?

Answer 11

2 is correct

Answer 12

ok thankyou so much

Answer 13

i have another

Answer 14

What is the value of z in the equation 4(2z + 3) = 12?

Answer 15

−13
12
0
12

Answer 16

\[5(2x-6)+20=10\]\[(5\times2x)-(5\times6)=-10\]\[10x-30=-10\]\[10x=30-10\]\[10x=20\]yeah you got it right
sorry for taking so long to type

Answer 17

hang on im almost done

Answer 18

i got 0? ithink that is right

Answer 19

(oops forgot one)\[x=\frac{20}{10}=2\]

okay next one:\[4(2z+3)=12\]\[(4\times2x)+(4\times3)=12\]\[8x+12=12\]\[8x=0\]\[\frac{0}{8}=x=0\]yep

Answer 20

ok

Answer 21

How many solutions does the equation y + 12 = y + 10 + 2 have?

Zero
One
Two
Infinitely many

Answer 22

10+2 = 12
both sides are equal.
what do you think?

Answer 23

i think its infinite many solutions

Answer 24

\(\text{Correct}\) ☺

Answer 25

ok

Answer 26

What is the value of y in the equation 4(5y − 8 − 2) = 185 − 15?

8.5
9.7
10.5
42.5

Answer 27

10.5?

Answer 28

\[4(5y-8-2)=185-15\]\[4(5y-10)=170\]\[(4\times5y)-(4\times10)=170\]\[20y-40=170\]\[20y=130\]\(y=\frac{130}{20}=\color{red}{6.5}\)

Answer 29

wait no I messed up lol

Answer 30

okay starting from \(20y-40=170\) again...\[20y=210\]\[y=\frac{200}{20}=10.5\]yeah you got it right

Answer 31

210* not 200 sorry

Answer 32

ok

Answer 33

this is the last one i dont get it

Answer 34

The steps below show the incomplete solution to find the value of x for the equation
6x + 10 − 4x = −4 − 11:

Step 1: 6x + 10 − 4x = −4 − 11
Step 2: 6x + 10 − 4x = −15
Step 3: 2x + 10 = −15

Which of these is most likely the next step?

2x = 5
2x = −25
2x = 25
2x = 150

Answer 35

they gave you the first 3 steps to solving the equation \(6x+10-4x=-4-11\) they want you to continue

Answer 36

ok

Answer 37

so now you have \(2x+10=-15\) how will you find x from this?

Answer 38

is it 2x=5?

Answer 39

no, close
when you move the 10 over to the right side it becomes -10\[2x\cancel{+10-10}=-15-10\]\[2x=-25\]

Answer 40

2x = −25

Answer 41

thank you much

Answer 42

no problem. happy studying ☺

Answer 43

i gave you a medal

Answer 44

I saw xD

Answer 45
