Answer:
60 serves
Step-by-step explanation:
According to the average, Sam should be able to hit 2/5 of his serves within the service lines.
If Sam hits 150 serves, find 2/5 of 150
2/5 * 150/1 = 300/5 = 60
Sam hit 60 serves within the service line during the match.

Let
x-----> the number of pounds of tomatoes Camilla bought
we know that
The equation that represent this situation is equal to
![1.15x=10-4.48](https://tex.z-dn.net/?f=1.15x%3D10-4.48)
Solve for x
![1.15x=5.52](https://tex.z-dn.net/?f=1.15x%3D5.52)
![x=5.52/1.15](https://tex.z-dn.net/?f=x%3D5.52%2F1.15)

Answer:
Molly has to add 22.86 milliliters of 5% sulfuric acid.
Step-by-step explanation:
Molly has a mixture of 20 ml of 20% sulfuric acid solution.
She mixes this with 5% sulfuric acid solution and in the end she wants a 12% sulfuric acid solution.
We have to find how many milliliters of 5% sulfuric acid we have to add to make it 12% solution.
Let the volume we add be v milliliters.
We are going to equate sulfuric acid.
![20\times 0.2 + v\times 0.05 = (20+v)\times 0.12](https://tex.z-dn.net/?f=%2020%5Ctimes%200.2%20%2B%20v%5Ctimes%200.05%20%3D%20%2820%2Bv%29%5Ctimes%200.12)
v =
milliliters
v = 22.86 milliliters
