2(x+10)=3x-30
2x+20=3x-30
x=50
Therefore, x=50 is your answer.
Remember that vertical angles, angles opposite from each other, have the same degree. That is why you can set up 2(x+10)=3x-30.
Answer:
13,5
Step-by-step explanation:
Find the length of the diagonal lines with Pythagorean theorem, and because it is already given that the lengths of the sides of the preformed shape are all equal, graph the 6th point with your information.
Answer:
23
Step-by-step explanation:
if you break this shape into 2 shapes it will be easier to solve
5(x-2) = 30
distribute the 5 by multiplying it with what is inside the parenthesis
5x-10 = 30
add 10 to both sides:
5x = 40
divide both sides by 5
x = 40/5
x = 8
I believe the answer is the third option.
1/2x is the slope and +3 is the Y-intercept which we already know is 3.
The graph is going up so its going to be a positive 3.
