What is the awnser of R plus 2s plus 3R?
It simplifies to: 2s+4R
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 .
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 9r squared-4s square over 9r plus 6s?
9r2-4s2/9r+6sIt looks like you can factors the numerator(3r + 2s)(3r - 2s) [This is the factored form of 9r2-4s2]Put this back into the equation(3r+2s)(3r-2s)/9r+6sYou can also factor the denominator3(3r+2s)Put this back into the equation(3r+2s)(3r-2s)/3(3r+2s)You can cancel out the 3r+2s on top and bottom because they are the same they equal 1. Therefore your final answer is3r-2s over 3You could go further and say this is...r-(2/3)seither one is correct
What is the airport code for Karumba Airport?
The airport code for Karumba Airport is KRB.
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
How many variables are in 7y 3r - 2s 5z - 3m?
They are: y, r, s, z and m which makes 5 of them
How do you factor 4s2-9?
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
What is equevitent to 7s plus 2s?
The equivalent of 7s plus 2s is 9s.
What is the answer to 2s-12 plus 2s equals 4s-12?
2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
What is the answer to 2s plus 16 equals 4s - 6?
2s + 16 = 4s - 6 Subtract 2s from both sides: 16 = 2s - 6 Add 6 to both sides: 22 = 2s divide both sides by 2: s = 11
