4k = 25 => k = 25/4 => 6< k < 7
15q = 160 + 24 => 15q = 184 => q = 184/15 => 12< q < 13

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.
