Answer:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.
Step-by-step explanation:
Answer: -10x + 1y = 2
Step-by-step explanation:
The standard formula says that Ax + By = C where A is the coefficient of the x variable, B is the coefficient of the y variable, and C is the constant value.
y = 10x + 2 Subtract 10x from both sides of the equation .
-10x -10x
-10x + 1y = 2
2x+7x= 180
9x=180
x=20
Plug the x value in to both expressions
2(20)=40
7(20)=140
Final answer: 40 degrees, 140 degrees
