What mistake was made when simplying the following expressions? 

#1. Y-15-3y+8

#2. 10(y-4)+4 

Wow, that all just confuses me!!

LOL, Yeah, I get tidbits of my mom's sometimes, it's delicous!

Me, Me !!!!!....especially the gourmet stuff.....

you use the division sign

so 1/4 or 2/5

the answer is 1 r.334

15m+7(17*13m) = -57+18m    simplify

15m +  7(221m)    = -57 + 18m

15m + 1547m  =  -57 + 18m    

1562m  =   -57  + 18m      subtract 18m from both sides

1544m  =  -57       divide both sides by 1544

m  =  -57 / 1544

-2  =  m

OK, but I really did read it. 

look, i'm sorry but your the one who posted a comment that took me completely off guard, howelse am I supposed to react??

OF COURSE I READ IT I READ EVERYTHING

I don't have two methods....but.....here's one.......call M  the original money that you started with....so we have.....

M - 33 - 15 - 20 =  21   simplify

M - 68    = 21      add 21 to both sides

M =  $89

3x690=2090. 

Lucky the cat would have 2,090 leaves in her collection.

I wasn't talking to YOU, I was talking to Calculus. 

If you don't know how to specify which root you want to take in your calculator, you can always write it as 1156.56^(1/3) . That is saying the same thing. :)

15 minutes  =  pi/2 rads  .......

And the distance it moves  =

rθ  =

6 inches * pi/2    ≈  9.42 inches

11.3 = r²

Square root both sides.

√(11.3) = √(r²)

3.361 ≈ r

haha very funny 

circumference = pi * diameter

circumference = pi *5 miles

Just plug this into a calculator.

circumference ≈ 15.7 miles

How... how l was born? Like every other person was... through some rather explicit means.

Move the term with the negative exponent to the denominator and get rid of the negative sign. If there's not already a denominator just put it under 1.
