hey try taking a picture of the question on photo math! helps me alot
A rate is a special ratio in which the two terms are in different units. <span>It is a comparison of measurements that have different units, like cents and grams. A unit </span>rate<span> is a </span>rate<span> with a denominator of 1. We calculate as follows:
rate = 7.5 cups of sugar / (14 x 12 cookies)
rate = 0.045 cups of sugar per cookie</span>
-33 < -7n - 12 < -26
First step is to add 12 to both sides.
-33 < -7n < -26-21 < -7n < -14
Now divide both sides by -7.
3 < n < 2
Because you divided by a negative number though, you need to switch up the signs. Both the < will turn into >.
3 > n > 2
