Answer:
Step-by-step explanation:
Given : A biologist studied how cells grow by adding liquid protein to cell samples.
She divided of an ounce of liquid protein evenly among 3 cell samples.
Here , total quantity of liquid protein = of an ounce
Total cell samples = 3
Now , Quantity of liquid protein given by her to each cell = (total quantity of liquid protein ) ÷ (3)
= .
Hence, Quantity of liquid protein given by her to each cell =

2(4 - 2r) = -2(r + 5)
First, divide both sides by -2. / Your problem should look like:
Second, regroup your terms. / Your problem should look like:
Third, add 4 to both sides. / Your problem should look like:
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:
Fifth, subtract r from both sides. / Your problem should look like:
Sixth, subtract 2r - r to get r. / Your problem should look like:
Answer: r = 9
