**Pre- Calc**

just put the clues into symbols: 4(r+b) = 3w+3 5(b+w) = 8r+13 w = b+5 now substitute for w in the 1st two equations: 4(r+b) = 3(b+5)+3 5(b+b+5) = 8r+13 or, 4r + b = 18 8r - 10b = 12 8r - 10(18-4r) = 12 48r = 192 r = 4 so, b=2 and w=7

**math**

distance = rate * time so, since the distance covered is the same both ways, .8r * (t+10) = rt .8rt + 8r = rt 8r = .2rt 8 = .2t t = 40 so, total time = 40+10 + 40 = 90 minutes

**math**

8 8r 8r^2 so 8 r^2 = 20 r^2 = 20/8 = 5/2 r = (5/2)^.5 so 8 8(5/2)^.5 8(5/2) 8(5/2)^1.5 8(5/2)^2 fifth term = 8(25/4) = 50 Sn = 8(1-r^n)/(1-r) S3 = 8 (1-(2.5)^1.5)/(1 -2.5^.5) 40.65

**Algebra**

add. (5r^4-3r^3+3r^2+14r-8)+(r^5+8r^3+7r^2-3r+5)+(-8r^4+r^2-8r-9)the answer I came up with is r^5-3r^4+5r^3+11r^2+3r-12. This is my first time doing this can someone help me to see if this is correct.That is one whole equation.

**Arithmetic**

ar^2 = 7/4 a/(1-r) = 14 a = 14(1-r) back into the 1st... 14(1-r)r^2 = 7/4 8(1-r)r^2 = 1 8r^2 - 8r^3 - 1 = 0 8r^3 - 8r^2 + 1 = 0 after a few trial-and-error attempts, I found f(1/2) = 0 ,so 2r-1 was a factor (2r-1)(4r^2 -2r-1) = 0 r = 1/2 or r = (1 ħ √5)/4 if r = 1/2 , ...

**pre algebra**

9r-5(r+6)=8r-2 ie; 9r-5r-30=8r-2 4r-30=8r-2 -4r=28 r=28/-4 r=-7
*Tuesday, July 14, 2009 at 2:03am by Ann*

**algebra**

I rewrite it according to terms. r+7r= 8r which is like saying 1+7=8 (then add back the variable) Same applies to the following: -6s+5s+s=0 which is like saying -6+5+1=0 3+0+5= 8 So you would end up with: 8r+8
