I believe you are right with all of them.
The solution of given equation is: -9
Step-by-step explanation:
Given equation is:
4x = -36
In order to solve these type of equations, we have to isolate the variable on one side of the equation
So in order to solve this equation, we have to divide both sides by 4
![\frac{4x}{4} = \frac{-36}{4}\\x = -9](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%20%3D%20%5Cfrac%7B-36%7D%7B4%7D%5C%5Cx%20%3D%20-9)
Hence,
The solution of given equation is: -9

Your answers are fine.
1) Transitive property if a = b and b = c, then a = c. Replace with your letters and is is done.
2) Symmetric property of equality.
If a = b, then b = a.
B.
Because it’s an acute angle
Answer:
18 (or more)
Step-by-step explanation:
Let's start off by creating an inequality:
Let "r" represent one pet rock
5r > 50 + 2r
Let's cancel out the 2r on the right side of the inequality by subtracting 2r from both sides:
5r > 50 + 2r
3r > 50
Now, to isolate r, we must divide both sides by 3:
3r > 50
r > 16.7
(Since we can't sell 16.7 pet rocks, we round up to 17)
r > 17
That means that Rosa has to sell at more than 17 pet rocks (so 18 or more pet rocks) to make profit.
