Find the radius of a circle with the equation x2 plus y2 equals 16?
x2 +y2 = R2 =16 = radius 2 R = 4
Q plus r equals s so t plus u equals?
v
R varies directly as s find r when s equals 7 and k equals 5?
Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35
Divide twelve by 4 then add seven what is the answe r?
The answer is 10 because 12 divided by 3 equals 4... and plus 7= 10
How do you solve 2r-7 equals 9?
2r - 7 = 9 (+7) (+7) >> add 7 to both sides so that only 2r is on that side 2r = 16 2r/2 = 16/2 >> divide both sides by 2 to isolate the variable r=8 >>16 divided by 2 is 8 which is your answer
What is 12 equals r over 3 plus 16?
12 = r/3 + 16
Solve r plus 11 equals 3?
You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7
R plus 16 equals 5r-10?
so 26 = 4r so r = 6½
What is 10 equals r plus 3?
10 = r + 3 Subtract 3 from each side: 7 = r
What is -5 equals 7 plus 3r?
If: -5 = 7+3r then the value of r works out as -4
13r plus 10 equals 5r - 46?
13r+10=5r-46 r= r = -7
What is r in this equation and how do you do it minus 5 equals 7 plus 3r?
-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r
What is 3 plus 10-r plus 6r equals -3 plus 9r plus 5-5?
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
Find the radius of a circle with the equation x2 plus y2 equals 16?
x2 +y2 = R2 =16 = radius 2 R = 4
-9 equals 20 plus r?
r=-29
What is the answer for r plus 8 equals 10?
r=2
Q plus r equals s so t plus u equals?
v
