Question

I need help with a math question. I linked it below. Also the drop down menus the first on says negative or positive and the second one says keep the same or reverse the same

Answer 1

The given inequality is expressed as

50 - 8t < 90

The first step is to subtract 50 from both sides. We have

50 - 50 - 8t < 90 - 50

- 8t < 40

The next step is to divide by - 8. Since we are dividing by a negative number, the inequality would be reversed. It changes from < to >. Thus, we have

- 8t/- 8 > 40/- 8

t > - 5

The arrow on the number line was supposed to point to the right side of - 5. Thus,

Mary divided both sides of the inequality by a negative value, so she needed to reverse the same inequality symbol
