Bob works as a tutor for an hour and as a waiter for an hour. this month, he worked a combined total of hours at his two jobs. let be the number of hours bob worked as a tutor this month. write an expression for the combined total dollar amount he earned this month.

1+1=2x30

Step-by-step explanation:

Because it is a expression, you don't have to solve it. You should first turn it into a promblem that you can solve. for example you know that bob workes two hours each day, and there are 30 days in a month. you would do 30 times 2 and get the answer 60, so it would look like this ,2h x 30d=$60. when i comes down to doing an expression it pretty much the same as solving the original problem.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.
