Answer 1

16° F.

Explanation:

Given:

The current temperature in Small town is 27 °F.

This is 5 degrees less than twice the temperature that it was six hours ago.

Question asked

What was the temperature in Small town six hours ago?

Solution:

Let the temperature in Small town six hours ago was
`x`

As given that the current temperature in Small town is 27 °F and this is 5 degrees less than twice the temperature of six hours ago, the equation will be:-

27 °F = 5 degrees less than twice the temperature of six hours ago

27 °F =
`2x-5`°

Adding both sides by 5

`27+5=2x-5+5\\32=2x`

Dividing both sides by 2

`(32)/(2) =(2x)/(2) \\16=x`

Thus, the temperature in Small town six hours ago was 16° F.
