Don't worry, I'll help.
For this you'll need to cross multiply

4m + 8 – 7
4m - 1
since you can't simplify anymore, you are correct.

n = 12
and yes

Answer 17

i could open up a new q so u could get more medals

Answer 18

Or..I can help you solve these first.

Answer 19

k lol thanks

Answer 20

b^-4= 1/81
Okay since ^-4 would end up making b / 4 = 1/81 the end result of b / 4 will have to equal 81, so 3 will not do.
What divided by 4 will equal 81?

Answer 21

324/4=81

Answer 22

yup. so b = 324

Answer 23

wow i was waaaayyyyyyyyy off

Answer 24

Now
What is the product written in scientific notation?
(2.6 × 10–4)(2.2 × 108)
A. 5.72 × 104 <--
B. 5.72 × 10–32
C. 4.8 × 104
D. 4.8 × 10–2

(2.6 × 10–4)(2.2 × 108) I'm assuming it's (2.6 * 10 - 4) right?

Answer 25

yes

Answer 26

actually lemme check cause my stuffs actin dumb

Answer 27

Okay.

Answer 28

nope its A. 5.72 × 10^4

Answer 29

Yah you're right it's A.

Answer 30

k thanks

Answer 31

and for the last one\
Solve.
2/3n=8
First you'll need to multiply both sides by 2 to isolate the 3m, 2/3n=8 becomes 3n=16
then just divide 16 by 3, your answer will be a decimal by the way.

Answer 32

k thanks again
