Answer 2

To simplify the given expression, let's start by distributing the coefficients:

6(2.5a - 0.8) - 5(0.8 - 1.4a)

Now, let's simplify each term:

= 6 * 2.5a - 6 * 0.8 - 5 * 0.8 + 5 * 1.4a

= 15a - 4.8 - 4 + 7a

Combine like terms:

= 15a + 7a - 4.8 - 4

= 22a - 4.8 - 4

= 22a - 8.8

Therefore, the simplified form of the expression 6(2.5a - 0.8) - 5(0.8 - 1.4a) is 22a - 8.8.
