What is the answer to 2r plus r plus 4g plus r?
4r+4g
What is an equivalent expression to (3r) plus (ar) plus (4r)?
It is (7 + a)r.
How do you keep the volume of a cylinder the same if the radius quadruples?
V = pi r^2*H & V = pi (4r)^2*h Equate pi r^(2)H= pi (4r)^2 h pi cancel down r^(2)H = (4r)^2h r^(2)*H = 16r^(2)*h 'r^(2) cancels down H= 16h h = H/16 This means is you increase the radius by '4 times' , then you reduce the height(H) by '16 times' in order to maintain the same volume.
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
What is the radius of a sphere whose volume is 972 pi cubic yards?
V = 972pi cu.yds V(sph) = (4/3) pi r^(3) Hence 972pi cu.yds = (4/3) pi r^(3) Cancel doewn by 'pi' 972 = 4r^(3) / 3 Multiply bo the sidex by '3' Hence 2916 = 4r^(3) Divide both sidesx by '4' 729 = r^(3) Take the cube root of both sides 729^(1/3) = r r = 9 yds.
What is 4r r in simplest form?
4r + 4 = 5r 4r - r = 3r 4r x r = 4r^2 4r/r = 4
How do you slimpify 4r plus r?
Since 4R and R both contain a like term (R), you can combine them: 5R would be 4R plus R simplified
What is the answer to 2r plus r plus 4g plus r?
4r+4g
What is -4r-9 plus r?
-13
How do you factor r2 plus 4r plus 4?
(r + 2)(r + 2)
How to solve 10 plus 4r 30?
If you mean: 10+4r = 30 then it works out that r = 5
22 plus 6r equals 4r plus 38?
r=8
What is the awnser of R plus 2s plus 3R?
It simplifies to: 2s+4R
What is an equivalent expression to (3r) plus (ar) plus (4r)?
It is (7 + a)r.
What is the answer to the following inequality -4r plus 6 equals 14?
-4r+6=14 isn't an inequality, its a linear equation. Anyway... -4r+6=14 (-6) -4r=8 (/4) -r=2 (x-1) r=-2
What is -2 - 6r plus 4r?
-2 - 2r or -2(1 - r)
How would you solve 4r plus 13 equals 57?
4r + 13 = 57subtract 13 from both sides:4r + 13 - 13 = 57 -134r = 44divide both sides by 4 to solve for r:4r/4 = 44/4r = 11
