Answer:

x=27

Step-by-step explanation:

we know that

(3x+9)^o+90^o=180^o ----> by supplementary angles (form a linear pair)

Solve for x

Combine like terms

(3x+99)^o=180^o

subtract 99 both sides

3x=180-99\\3x=81

Divide by 3 both sides

x=27

Pls answer “b” correctly and I will mark it has brainlist
Phoenix [80]
Since it is a slope, the equation of a slope is y=Mx+b. So you want to get b to that format. To do this, you need to isolate the y on the left. To do this, you simply add 2x to both sides. Your final answer will be y=2x+7. Hope this helps!

PLEASE HELP AGAIN. IM TIMED
Law Incorporation [45]

Answer:

B, 3 8/9

Step-by-step explanation:

It all comes down to equivalent fractions.

2 1/3 as an improper fraction is 7/3.

1 5/9 as an improper fraction is 14/9. 1/3 = 3/9.

With that being said 7 x 3 = 21 resulting in 21/9.

14/9 + 21/9 = 35/9.

35/9 as a mixed fraction is 3 8/9.
