12 = r/3 + 16

You subtract 11 from both sides and r equals negative 7. See... r+11=3 -11 -11 r=7

so 26 = 4r so r = 6½

10 = r + 3 Subtract 3 from each side: 7 = r

If: -5 = 7+3r then the value of r works out as -4

13r+10=5r-46 r= r = -7

-5 = 7 + 3r | subtract 7 -12 = 3r | divide by 3 -4 = r

3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4

r=-29

r=2

v

x2 +y2 = R2 =16 = radius 2 R = 4

r+5r+5=-25

r + 11 + 8r = 29

If: -7 = 7-2r Then: r = 7

25

It is an equation and the value of r is 66

r=8

Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35

5s-r

r -31

r + 14 = 39 r = 25

r = 25

r = 4
