12d - 9 = 15d + 9 Subtract 15 d from both sides: -3d - 9 = 9 Add 9 to both sides: -3d = 18 Divide both sides by -3: d = -6
12 plus 9 equals 21.
144 9+7 = 16 and 9*16 = 144
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
12d - 9 = 15d + 9 Subtract 15 d from both sides: -3d - 9 = 9 Add 9 to both sides: -3d = 18 Divide both sides by -3: d = -6
9 plus 87 equals 96.
12 plus 9 equals 21.
No! It equals 15, but 9-6=3.
96
9+9+9+9 = 36
If I am correct, 9 plus 7 equals 112.
144 9+7 = 16 and 9*16 = 144
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
9+9+9+9+9+9+9=63
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
The answer to the expression 3x + 9 depends on the value of x. If x is a specific number, you would first multiply 3 by that number, then add 9 to the result. For example, if x = 2, the answer would be 3(2) + 9 = 6 + 9 = 15. However, if x is a variable, the expression 3x + 9 remains as is and cannot be simplified further without knowing the specific value of x.
