Solve for m.

Answer 2

so m is being multiplied by c and divided by r. how do we undo this?

Answer 3

It would be m divided by c and multiplied by r..?

Answer 4

good, so after we apply those operations, we get m by itself on the right side

Answer 5

now, we divide E by c and multiply it by r

Answer 6

A?

Answer 7

yes good

Answer 8

Solve for x.

Answer 9

so how do you think we can "undo" the + b on the right side?

Answer 10

- b?

Answer 11

good, that gives us

y - b = mx

now, how do we get x by itself?

Answer 12

Cross out A and B ^-^

Answer 13

Sorry, spider attacked -.-

Answer 14

Is it C?

Answer 15

Is you alive or did my spider come to you? Because I can't find it lol

Answer 16

if we have y - b = mx

how can we "undo" the multiplication by m?

Answer 17

ಠ_ಠ

Answer 18

again, think about our calculator example

Answer 19

if x is being multiplied by m, then how can we get "x" by itself and "undo" the multiplication?

Answer 20

D?

Answer 21

please answer my question

Answer 22

we have mx

how can we "get rid of" the m?

Answer 23

Division?!

Answer 24

yes, divide by m

Answer 25

y - b = mx

now divide both sides by m and let me know what you get

Answer 26

There's no numbers, how do I divide letters???

Answer 27

write a division sign

then write m in the denominator

Answer 28

y-b/m

Answer 29

remember that variables are just letters that stand for numbers, you can perform operations too

Answer 30

good, don't forget the parentheses

Answer 31

(y-b)/m = x

which answer choice matches?

Answer 32

There's no parentheses .-.

Answer 33

D.

Answer 34

good, D

Answer 35

the reason we add parentheses is that

y - b/m implies that only b is divided by m
we want to divide the entire expression by m, so we write (y-b)/m

Answer 36

These are hard. Worse quiz ever.
