15 and 24, respectively.
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
12r + 4 = 112, 12r = 108, r = 9
It's an incorrect statement. 5 plus 6 equals plus 11. Also, pi R round, cornbread R2 .
r=-29
|2r + 9| = 5 So 2r + 9 = 5 or 2r + 9 = -5 so that 2r = -4 or 2r = -14 r = -2 or r = -7
r+5r+5=-25
-8
-9
15 and 24, respectively.
This is the associative law for addition: If a, b, c are any numbers then: a + (b + c) = (a + b) + c
r2 + r - 20 = 0(r + 5)(r - 4) = 0r + 5 = 0 or r - 4 = 0r = -5 or r = 4
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
If: -5 = 7+3r then the value of r works out as -4
r = 5k + 5ur - 5u = 5kk = r/5 - u
