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: 6 or 12/2
Step-by-step explanation: 3/2 x 4/1= 3x4/2x1 = 12/2 = 6
Depends on what equation it is
Answer:
Step-by-step explanation:
Subtract 57 from both sides:
Divide both sides by 4:
Answer:
false
Step-by-step explanation:
I'm not sure how to answer this. How you need to do is take the two smaller sides and add them. If they are greater than the largest side, you can make a triangle.
I would say that the statement is false. If you subtract, you could get a minus number, and that would be an absurd result.
