Make P the subject. Q = 3P + 2

Ne4ueva [31]

Answer:

P = $\frac{Q-2}{3}$

Step-by-step explanation:

Q = 3P + 2 ( subtract 2 from both sides )

Q - 2 = 3P ( isolate P by dividing both sides by 3 )

$\frac{Q-2}{3}$ = P

Scientists have found that the life span of a mammal living in captivity is related to the mammals mass. The life span in years

Tatiana [17]

To know the life span of the wolf and the lion, we simply substitute their mass to the formula for L.

Mass of wolf:
$L=12 m^{ \frac{1}{5} }= 12 (32)^{ \frac{1}{5} }=24$

Mass of lion:
$L=12 m^{ \frac{1}{5} }= 12 (243)^{ \frac{1}{5} }=36$

Therefore, the wolf has a life span of 24 and the lion has a life span of 36. With this information, we can determine how much longer the life span of the lion is:
$36-24=12$

ANSWER: The life span of the lion is 12 longer than the life span of the wolf.
