What is a and b if a plus b equals 25 and a times b equals 126?
The values of a and b are 7 and 18 or 18 and 7
What is the value of b to make the number sentence true for b plus b plus b plus 7 equals b plus 22?
b + b + b + 7 = 223b + 7 = 223b = 15b = 5
IF 2 plus 3 equals 10 7 plus 2 equals 63 6 plus 5 equals 66 8 plus 4 equals 96 THEN 9 plus 7 equals?
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.
A square plus b equals 7 and a plus b square equals 11 what are the values of a and b?
A^2 + b = 7 A + B^2 =11 -------------- A=2 and B=34(2^2) + 3 = 7 2 + 9(3^2) = 11
What is the value of a if ab plus ac equals 21 and b plus c equals 7?
To find this: You know (B+C) = 7. Therefore you know (A+A )= 21 - (B+C). Therefore 21-7 = 14. So now you know (A+A) = 14. So you divide (A+A)/2. This equals 7. Therefore A = 7.
