If we factor -1/4 out of that expression it looks like this: -1/4(2x + 5)
In order to do this, we need to divide each term by that -1/4. Then use them in a parenthesis together.
(-1/2x)/(-1/4) = 2x
(-5/4)(-1/4) = 5
So we use them together at (2x + 5)
Since a plane is 180 degrees total, x=135
180-45=135
Answer:
So, the first one is not proportional and therefore has no multiplier.
You are right on the second on both counts!
Step-by-step explanation:
You just need to divide the x's by the y's (individually) in order to determine what they are multiplied by. And the answers you get for the first one will be 5, 6, and 7. Because the numbers are different, they are not proportional.

This is the answer..
Plss mark me as brainliest.
Answer:
Step-by-step explanation:
For the first one, revenue - cost = profit. We have equations for revenue and profit, so filling in:
Let's add cost to both sides to make it positive and bring everything on the right over to the left and combine like terms:
For the second one:
P(x)*T(x) = 
Distribute the 3x into everything inside the parenthesis to get
For the second part of that problem, C(x)*P(x) = 
Distribute the x into everything first to get:
The distribute the -4 into everything to get:
Combine the like terms and put everything together to get
