t = 12r/(r+120)

t(r+120) = 120r

tr+120t = 120r

tr-120r = -120t

r(t-120) = -120t

r = -120t/(t-120)

r = 120t/(120-t)

Which of the following is an equivalent form of the compound inequality −22 &gt; −5x − 7 ≥ −33?
alexgriva [62]

An equivalent form of the compound inequality −22 > −5x − 7 ≥ −33 will be −5x − 7 > −22 and −5x − 7 ≥ −33

<h3>Compound inequality</h3>

A compound inequality (or combined inequality ) is two or more inequalities joined together with inequality operations.

Given the compound inequality −22 > −5x − 7 ≥ −33, this can also be splitted into;

−22 > −5x − 7 and  −5x − 7 ≥ −33,

The inequality expression  −22 > −5x − 7 is also expressed as  −5x − 7 > -22. Hence an equivalent form of the compound inequality −22 > −5x − 7 ≥ −33 will be −5x − 7 > −22 and −5x − 7 ≥ −33

Explanations or answers, please!!!
Oksi-84 [34.3K]
For question 1A. each mug will be 1/9 because 4/9 divide by 4 is 1/9B.  3/9 or 1/3 because 1/9 times 3 is 3/9

For question 2 5/6 divide by 4 equals 5/24. So each plot would be 5/24 km squared. Multiply that by 3 and it would be 15/24. So the answer would be 15/24 km squared if i'm correct.

Hope i helped!!
