Question

Ranger simplified this expression. 3(2.7x + 5) – 2(4x – 1.6) What was Ranger's simplified expression? 0.1x + 18.2 –16.1x + 11.8 16x – 18.2 –0.1x + 11.8

Answer 1

Answer:

Ranger's simplified expression was 0.1x + 18.2

The correct answer is the first option.

Step-by-step explanation:

To simplify the given expression

3(2.7x + 5) – 2(4x – 1.6)

First, we will open the brackets by distributing 3 and 2, that is

(3×2.7x) + (3×5) -(2×4x) -(2×-1.6)

Now, we will get

8.1x + 15 - 8x +3.2

Now, collect like terms,

8.1x - 8x + 15 + 3.2

Then, we will get

0.1x + 18.2.

Hence, Ranger's simplified expression was 0.1x + 18.2.

The correct answer is the first option.
