You have a system of equations going on here. The first one is already set equal to a. So let's take that part of the equation, the p + 15, and sub it in for the a in the other equation: 5(p + 15) - 525 = 2p. Now what we have is an equation to solve that is only in terms of p, not p and a. We cannot solve an equation with 2 unknowns. Making that substitution eliminates the a, the second unknown. Now distribute the 5 into the parenthesis to get 5p + 75 - 525= 2p. Move the 2p over to the left and move the other terms over to the right and combine all the like terms to get 3p = 450. Dividing both sides by 3 gives you that p = 150. Now take that p value and sub it into the p + 15 = a to get 150 + 15 = a and a = 165
That one is self-explanatory if you follow a video on it it will help
Answer:
<em>P</em> + (.25)(<em>P</em>)
Step-by-step explanation:
First off I WANT A DIAMOND PONY :)
<em>P</em> stands for what the price of the pony is, and (0.25)(<em>P</em>) is the diamond pony tax that has to be added to the original price.
Hope I helped, and if you are extremely grateful, send me a diamond pony :D

Answer: 9.85 inches
Step-by-step explanation:
Each point on the graph represents the total rainfall in one month in this desert. For instance, the 2 points on top of 1.0 inches indicates that there were two months in the year where rainfall was 1.0 inches.
The total rainfall in this desert was therefore:
= 0.4 + 0.5 + 0.5+ 0.6 + 0.85 + 0.85 + 0.95 + 1.0 + 1.0 + 1.05 + 1.05 + 1.1
= 9.85 inches
