d) -9.8b + 9

Answer 1

To add the expressions -6.5b + 11 and 3.3b - 2, you combine the like terms by adding the coefficients of 'b' terms and the constant terms. The result is -3.2b + 9.

Step-by-step explanation:

To add the two expressions -6.5b + 11 and 3.3b - 2, we simply combine the like terms. The like terms in this case are the ones with the same variable, which is 'b'. We add the coefficients of the 'b' terms and keep the result with 'b' as the coefficient. For the constant terms, we add them together.

-6.5b + 11 + 3.3b - 2 = -3.2b + 9
