<span>Gicen:
5p+9c=p
Manipulating the terms:
step 1) Subtract 5p from both sides
</span><span>5p-5p+9c=p-5p
</span>we get:
9c = -4c
divide 9 on both sides
c = (-4/9)c
Add all of the numbers together , and then divide by how many numbers your adding up. in this case you would divide by 8.

Answer:
Answer 7
Step-by-step explanation:
This depends on setting up a proportion
5:45 :: 3: 3 + 2x + 10
You can reduce 5 / 45
5/45 = 1/9
1:9 :: 3:3 + 2x + 10
1:9 :: 3: 2x + 13
1/9 = 3/(2x + 13) Cross Multiply
2x + 13 = 3*9
2x + 13 = 27 Subtract 13
2x + 13 - 13 = 27 - 13
2x = 14 Divide by 2
2x/2 = 14/2 Divide
x = 7
