Question

What is the simplest form of the expression (14.2a +9.8b)-(13.15-0.2a)-(3.7a+ 4.80)7 O 10.7a-8.lb​

Answer 1

First, let's simplify the terms in parentheses:

(14.2a + 9.8b) - (13.15 - 0.2a) - (3.7a + 4.80) = 14.2a + 9.8b - 13.15 + 0.2a - 3.7a - 4.80

= 10.7a + 8.0b - 18.95

Now we can simplify the entire expression:

(14.2a + 9.8b) - (13.15 - 0.2a) - (3.7a + 4.80) = (10.7a + 8.0b - 18.95) / 10

= 1.07a + 0.8b - 1.895

Therefore, the simplest form of the expression is 1.07a + 0.8b - 1.895.

Answer 2

Let's simplify the given expression step by step:

= (14.2a + 9.8b) - (13.15 - 0.2a) - (3.7a + 4.80)

= 14.2a + 9.8b - 13.15 + 0.2a - 3.7a - 4.80 (distributing negative sign)

= (14.2a + 0.2a - 3.7a) + 9.8b - 13.15 - 4.80 (grouping like terms)

= 10.7a + 9.8b - 17.95

Therefore, the simplest form of the expression (14.2a + 9.8b) - (13.15 - 0.2a) - (3.7a + 4.80) is 10.7a + 9.8b - 17.95.
