Answer: 
Step-by-step explanation:
Given equation: 
Since 5 is the greatest common factor of 65 and 60 in the given expression.
Therefore, the above expression can be written as
Hence, by factoring the side that contains the variable p we have the expression .
Answer:-2
Step-by-step explanation:3(4) - (-2) ÷ 6(-2) + 4
= 12 + 4 ÷ -12 + 4
= 16 ÷ -8
= -2
Answer:
Subtract 
from both sides.
Step-by-step explanation:
We want to isolate the variable 
. To do this, we have to get rid of , which we can do by subtracting itself, since it equals 0.
How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment?
1. Look at how 60% is closer to the solution of lower concentration (50%). You can deduce that you will be mixing a higher volume of the 50% solution.
2. All 4 answers add up to 105ml.
3. The intuitive answer is the first option:
70 ML of the 50% solution and 35 ML of the 80% solution
4. Let's check whether point 3 is true.
70ml/105ml X 0.5 + 35ml/105ml X 0.8 = (35 + 28)/105= 63/105= 60% / 105 ml = 105ml of 60% sugar solution
14 because 28 divided by 2 is 14
