Mary has 20 liters of paint mixed white:blue in the ratio 2:3. So two fifths of that paint is white and three fifths is blue. So that's 8 liters white, 12 liters blue.
We want to add paint to get white:blue = 1:7. Clearly we need to add blue. We have our 8 liters of white, so we need a total of 7(8)=56 liters of blue. We already have 12, so we have to add 56-12=44 liters of blue paint:
Answer: Add 44 liters blue

Formula for mean:

Putting values, we get:

Thus, the highest score is 32.
6. Factor 4x from 22x2 + 40x 6.
is that multiply 4x 22x2 +40x6
Answer:
See below and attached
Step-by-step explanation:
Let the number of paintings is x and the number of mugs is y.
<u>We have following inequalities:</u>
- x + y ≤ 350
- 20x + 15y > 4500
The graphical solution is attached.
<u>The solution is:</u>
- 225 < x ≤ 350
- 300 < y ≤ 350
