What is r squared minus 4?
That's not possible to simplify, or give an answer to, unless you know what 'r' is.
What is the awnser of R plus 2s plus 3R?
It simplifies to: 2s+4R
R plus s equals 4 2r plus 3s equals 8?
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
What is the sum of 2r and 2s?
since you do not know what r and s is all you need to write is... 2r + 2s the sum just simply means add them together.
What is r-4 divided by 9?

Reen is twice as old as SUnita Three years ago she was threetimes as old as Sunita How Old is Reena Now?
R = 2S(R) - 3 = 3 (s - 3)(2S) - 3 = 3s - 9-3 = s - 9S = 6R = 12
2r plus 2s equals 50 and 2r minus s equals 17?
2r + 2s = 50 2r - s = 17 therefore 4r - 2s = 34 Add so that you can eliminate one of the variables: 2r + 2s = 50 4r - 2s = 34 ---------------- 6r + 0s = 84 Solve for r: 6r = 84 r = 14 Substitute r into one of the original equations: 2(14) + 2s = 50 28 + 2s = 50 2s = 22 s = 11 Doublecheck with the other original equation: 2(14) - 11 = 28 - 11 = 17
Ralph is 3 times as old as Sara In 6 years Ralph will be only twice as old as Sara will be then Find Ralph's age now?
1) 3S = R 2) R+6= 2 (S+6)= 2S+12 ----> R=2S+6 1,2 )--> 3S = 2S+6 ---> S=6 & R= 3 x 6 = 18 Ralph is 18 & Sara is 6 .
R plus s equals 4 2r plus 3s equals 8?
r + s = 4 and 2r + 3s = 8 multiply the first equation by 2 giving 2r + 2s = 8 subtract this from the second equation giving s = 0 So r = 4 and s = 0.
what- choose the property of equality that justifies the step. prove: if q= 8r+ 12, r= 2s +1, and s = 4, than q= 84.?

What is the sum of 2r and 2s?
since you do not know what r and s is all you need to write is... 2r + 2s the sum just simply means add them together.
