Q.

-3.6 - 1.9t + 1.2 + 5.1t

Combine Constants: We need to combine like terms to simplify the expression. The like terms are the constants $-3.6$ and $1.2$ and the terms with $t$ $-1.9t$ and $5.1t$ . First, let's combine the constants: $-3.6 + 1.2$ .
Calculate Sum of Constants: Calculating the sum of the constants: $-3.6 + 1.2 = -2.4$ .
Combine Terms with $t$ : Next, we combine the terms with $t$ : $-1.9t + 5.1t$ .
Calculate Sum of Terms with t: Calculating the sum of the terms with t: $-1.9t + 5.1t = 3.2t$ .
Combine Results: Now we combine the results from the previous steps to get the final simplified expression: $-2.4 + 3.2t$ .
