Teresa makes brownies in the oven for 55 minutes. she checks on the brownies after 36 minutes. how much longer do the brownies need to bake?

For this case we have to indicate how much time the brownies are needed to bake, knowing that 55 minutes are given and Teresa reviewed them after 36 minutes.

For this we subtract:

So brownies have 19 minutes to bake

19 minutes

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
