Question

chemical A freezes at 13° lower than chemical B. if chemical A freezes at -36° C, at what temperature does chemical B freeze? Let B =B's freezing temperature.

Answer 1

-23 ° C

Explanation:

With the data of the statements we can propose the following equation

`-13=A-B`

We replace by A and solve for B:

`\begin{gathered} -13=-36-B \\ B=-36+13 \\ B=-23 \end{gathered}`

Chemical B freezes at -23 ° C
