So you know all angles in a triangle add to 180 degrees and you have x + 3x + 2x which adds to 6x so you do 180/6 to get x = 30 and c = 2x so you do 30 x 2 which is 60 degrees. Hope this helps :)
This system has one solution. Here are my steps to solving this problem:
y=x+1
2(x+1) - x = 2
2x +2 - x = 2
2x - x + 2 = 2
x + 2 = 2
- 2 - 2
----------------
x = 0
y = 0 + 1
y = 1
I hope this helps you!
I believe it should be B.156 square feet because in order to find the area of a square, you gotta multiply 13ft and 12ft. Once that is solved your answer should be 156.
Answer:
Can help things alot more easier,
Step-by-step explanation:
For instance, all the multiples of 9. Add up to 9
18
27
36
45
etc.
As written here, both choices B and C represent proportional relationships:
... B. y = 12x
... C. y = 3x
_____
One key to a proportional relationship is that when one variable is zero, so is the other. This will not be the case for selections A and D.
