Help a young stupid blond (: 9(-5-r) = -10-2r ?

9(-5-r) = -10-2r

-45-9r = -10-2r

-35-9r = -2r

-35 = 7r

r=-35/7

------------------------

2/3(3x-9) = 4(x+6)

2x-6 = 4x+24

-6 = 2x+24

-30 = 2x

x = -15

-------------------------

6m-3 = 10-6(2-m)

im guessing that your multiplying 6*m*-3 and your subtracting 10-(6(2-m)) so

-18m = 10-(12-6m)

-18m = 10-12+6m

-18m = -2+6m

-24m = -2

m = 1/12

9(-5-r) = -10-2r is?

Solution: r=-5

21. 2/3(3x -9) = 4(x + 6)?

Solution: x=5.09302325581395

22. 6m -3 = 10 - 6(2-m)?

Solutions: m=0.0602409638554217

np:)

Easy.

9(-5-r)=1-=2r

-45-9r=10-2r

+9r +9r

-45=10+7r

-10 -10

-55=7r

-55 divided by 7, 7rdivided by 7

8=r

sry i dont have a calculator on me. its just like the first one i did. hope you learned something today=)

im pretty sure about this

1. r=5

2. x= -15

for number 3 im thinking is no solution or 11/2 = 5.5

-45-9r

2x-6

-12+6m

First one: R= -5

Second one: X= -5

Third one: M=12/5

Not going to help you with your math. But, i would like to give you props on playing the "dumb blond" card. It actually works sometimes. Now, if you truly are dumb and happened to be blonde, never mind.

im not a blonde and i dont know what that is

its like if a doctor wrote a prescription

NO!
