What is 2.3c-5.25(2.6d-2.8)-7.9 simplified?

Answer 1

To simplify the expression (2.3c - 5.25(2.6d - 2.8) - 7.9), first distribute (-5.25) through the parentheses:

(-5.25 \times 2.6d + 5.25 \times 2.8 = -13.65d + 14.7).

Now substitute back into the expression:

[2.3c - 13.65d + 14.7 - 7.9].

Combine the constant terms (14.7 - 7.9 = 6.8), resulting in the simplified expression:

[2.3c - 13.65d + 6.8].
