Question

Can anybody please help?

Answer 1

For question 2 I am confused. But for question 3 is B the correct answer?

Answer 2

yes they are supplemantery .. which means they equal 180 together

Answer 3

the line FG is twice long as line BC, therefore

2(3.5x+4) = 3(3x+1) +1 solve for x

Answer 4

FG is 1/2 of BC, that is what I meant, that is why you multiply by 2

Answer 5

@ivettef365 I got to this point 3.5x = (1/2)9x.
Is it correct? How do I simplify now?

Answer 6

the way I organized is better to simplify

2(3.5x+4) = 3(3x+1) +1
7x + 8 = 9x +3 +1
7x + 8 = 9x + 4
8-4 = 9x - 7x
4 = 2x so x = 4/2

Thank you so much!
