Question

Write an inequality for each situation.

Answer 1

Answer:

A. 56-6m<20

B. 2.95b+28<450

13. Less than, greater than, going over or not going over.

Step-by-step explanation:

A. The answer to the first question can be simple. If she can scan 6 photographs per minute, then we would write the inequality 56-6m<20, since we are subtracting 6 from 56 every minute, we would write 6 per minute as 6m, and subtract that from 56. Lastly, since it says less than, we need to put the less than symbol, the mouth facing towards the 20 as the greater number.

B.  If she has spent 28, that means that we put -28 on the equation as a constant. Then, we put the price times the number of batteries she bought, or 2.95b, and put a less than symbol, since we want to spend less than the 450 gift card. So the equation would be 2.95b+28<450

13. Key words to indicate inequalities can be less than, greater than, without going over, going over.
