The error occurred in step 2. You have to use the distributive property for the parenthesis. It is supposed to be 5p+15.
The correct solution is p>-13.
Answer:
x = -2
Step-by-step explanation:
-20 = -4x - 6x + 2(10x)
Simplify both sides:
-20 = -4x - 6x + 20x
Combine like terms:
-20 = 10x
Isolate the variable:
x = -2

Answer:
x² +y² = 14x
Step-by-step explanation:
Making the usual substitution x = r·cos(θ) and r² = x² +y², we can get there this way:
Substitute cos(θ) = x/r:
r = 14·x/r
Multiply by r:
r² = 14x
Substitute for r²:
x² + y² = 14x

Answers:
1: No, 10/12 Simplified is 5/6, and 15/30 simplified is 1/2
2: Yes, 1/5 / 3/5 Simplified is 1/3, and 1/4 / 3/4 simplified is 1/3
3: 60 words, You do 300 divided by 5, and you get 60 per minute
4: 240 words, You take the 60 per minute, and you multiply is by 4.
5: 24 doughnuts, 20x3 is 60 minutes. So, 12 doughnuts in one hour. Multiply is by 2, and you get 24 doughnuts per hour.
6: Walmart, To find out how much it costs, you so 1.25 / 5, and 0.80 / 2. So, Walmart is 0.25 per pack, and Ingles is 0.40 per pack. So, you can automatically tell that Walmart is cheaper, meaning the better buy.
