Question

A+A+A =21
B+B+ B= 30
C+C-C= 15
A+B×CCC=?​

Answer 1

The value of of A + B x 3C is 457.

Step-by-step explanation:

A + A + A = 21

=> 3A = 21

=> A = $\frac{21}{3}$ = 7.

B + B + B = 30

=> 3B = 30

=> B = $\frac{30}{3} = 10$

C + C - C = 15

=> C = 15

A + B x (3C) = 7 + 10 x (3 x 15) = 7 + 10 x 45 = 7 + 450 = 457.

Hence, the value of of A + B x 3C is 457.
