Question 403009: i don't think that i selected the right topic for what i'm doing. i'm in pre-algerbra 7th grade. this is my problem, 5/8(p-4)= 2. i think you use distributive property, bring down 5/8 and make it 5/8p. multiply 5x4=20. 8x4=32, make that a fraction,20/32. 5/8p - 20/32=2. do you make the dimoninateors the same? so, multiply 5/8p by 4? so now it would be, 20/32p. this is where i'm stuck!the written problem would now be, 20/32 - 20/32p=2. would you resipical the 20/32 to 32/20? discard it. the problem now who be, 20/32p=2. would you make the 2 into 2/1 and multiply it by 32/20? 2/1 x 32/20 =32/10 which is reduced down to 3 1/5 is that the correct answere?

Question 406680: Could someone please check these problems for me to see if I have done them right?
(-9)(5)/-3=(-45/-3=15=-15
4-(-3)+1/2-2divided by(-2)=8/2+1=8/3=2 2/3
9^2-(-6)^2=9^2-(-36)=81+36=117=-117
(-9)(5)/-3=(-45)/-3=15=-15
(-6)^2-4^2=(-36)-4^2=36+16=52=-2-52

Question 409167: I have been studying all day and doing practice problems from my math book to get me ready for a test. I am stuck at 3.1 in my book. I am to this point and i do not understand how to solve a problem like the following:
simplifying expressions:
3+6(w+2)+w
I know I have to use the distributive property, Where I am confused is what do I do with 3+6 Do i add this and then use the answer to distribute over (w+2) and then add +w? I just really need to know the steps so that i can practice more problems like these
