in 7-10, simplify each expression.

1. -2.8f + 0.9f - 12 - 4

Explanation:

Step1: Combine like terms for the variable part

We have \(-2.8f + 0.9f\). To combine these, we add the coefficients: \(-2.8 + 0.9 = -1.9\), so this part simplifies to \(-1.9f\).

Step2: Combine the constant terms

We have \(-12 - 4\). Subtracting these constants: \(-12 - 4 = -16\).

Step3: Combine the results from Step1 and Step2

Putting the simplified variable part and the simplified constant part together, we get \(-1.9f - 16\).

Answer:

\(-1.9f - 16\)
