Question

1. Evaluate 10b + 3c, f b = 3 and c = 11. A. O 27 B. O 43 C. O 66 D. O 63

Answer 1

We have to evaluate the expression:

10 b + 3 c

for b = 3 and c = 11

So, we replace b and c by their respective values, and proceed to operate:

10 (3) + 3 (11) = 30 + 33 = 63

where the product 10 times 3 = 30, and the product 3 times 11 = 33

where completed BEFORE we add them, following the rules of mathematical operations.
