dont be srry, u ii

Answer 6

Let's do #5 *-*

We have \(\tt \color{red}{\dfrac{b}{47}= -2}\) To solve this you must:

\(\tt \color{red}{Multiply~47~on~both~sides~of~the~equation.}\)

So, now we have \(\tt \color{red}{\dfrac{b}{47}\times47= -2\times47}\)

Do you know how to simplify this? Once you do, you will get your answer :)

Answer 7

so do -2x47?

Answer 8

Right

Answer 9

And that's your answer for #5. Tell me what you got :)

Answer 10

b=(-94)

Answer 11

Correcto *-*

Now let's do #4: \(\tt \color{red}{4= \dfrac{s}{-14}}\)

Do you have an idea on how to solve this?

Answer 12

i would do -14/4?

Answer 13

Not quite, you would \(\tt \color{red}{multiply}\), since you are originally \(\tt \color{red}{dividing}\).

Answer 14

So, \(\tt \color{red}{-14\times4}\)

Answer 15

-56

Answer 16

s=(-56)

Answer 17

Correct again ^-^ #4 is -56.

Let's do #3: \(\tt \color{red}{\dfrac{t}{-3}=12}\)

Do you know what to do on this one?

Answer 18

12x-3?

Answer 19

Right, which is?

Answer 20

t=-36

Answer 21

Right *-*, so #3 is -36

Now for #2, we do the opposite since we are originally multiplying.

\(\tt \color{red}{7r=-56}\)

We have to \(\tt \color{red}{divide~7~on~both~sides}\). What do you think the answer is?

Answer 22

SO....-56/7

Answer 23

Yeppers :)

Answer 24

UM...I GOT SUM REALLY LONG NUMBER

Answer 25

You shouldn't. Make sure you type -56/7 and not 7/-56

Answer 26

i got -8.142857143

Answer 27

Sure you typed everything correct?

Answer 28

yep stll got the long number

Answer 29

You typed -57/7, not -56/7

Answer 30

X___x

Answer 31

I GOT -8

Answer 32

^-^ It's ok. It happens a lot, and that is right, so #2 is -8

Answer 33

r=-8

Answer 34

i think ik #1

Answer 35

What do you think it is?

Answer 36

y=-32

Answer 37

cause u remeber the teachers saying if the letter by itself it counts as a 1 in front of it

Answer 38

Close, but not quite.

Now for #1, we have \(\tt \color{red}{-y = -32}\), since they are both negative, your answer should be positive

Answer 39

OH OK

Answer 40

y=32

Answer 41

If y = -32, then we would have - - 32 = -32, which isn't right :P

Answer 42

Right *-*

Answer 43

Good job :)

Answer 44

YAY...i feel smart

Answer 45

i think i can do the other 16 by myself

Answer 46

Okie dokie. Once you finish you can post it here and I can check it if you want.

Answer 47

ok
