Question

One night, it is 24 ℃ warmer in Tucson than it was in Minneapolis. If the temperatures in Tucson and Minneapolis are opposites, what is the temperature in Tucson?

Answer 1

The temperature in Tucson is 12°C, and that of Minneapolis is -12°C.

Explanation:

Let the temperature in Tucson = T

And the temperature in Minneapolis = -T. Because the temperatures are opposites.

Since we know that it is 24°C warmer in Tucson that it was in Minneapolis, then

T - (-T) = 24

T + T = 24

2T = 24

T = 24/2

= 12

Therefore, the temperature in Tucson is 12°C, and that of Minneapolis is -12°C.

Answer 2

The temperature in Tucson is
`12\,^(\circ)C`.

Explanation:

Let be
`T` and
`-T` the temperatures registered in Tucson and Minneapolis, respectively. The difference between both temperatures is:

`T - (-T) = 24\,^(\circ)C`

`2\cdot T = 24\,^(\circ)C`

`T = 12\,^(\circ)C`

The temperature in Tucson is
`12\,^(\circ)C`.
