Answer:
the answer would be B y=x+9/4
Step-by-step explanation:x=4y-9 switch sides 4y-9=x then add 9 to both sides 4y-9+9=x+9
then 4y=x+9 simplify 4y/4=x/4+9/4 then simplify y=x+9/4 that your answer B y=x+9/4
I'm sorry, I truly wanted to help, but honestly, I'm clueless and I've viewed all three of you questions.

Step-by-step explanation:
Solving (a):
Let the numbers be: ![x, x + 1, x + 2.](https://tex.z-dn.net/?f=x%2C%20x%20%2B%201%2C%20x%20%2B%202.)
Their sum is:

Answer:
Step-by-step explanation:
From the data given,
∠MON=8x−13
∠LOM=7x−17
∠LON= is a straight line angle, i.e. it is 180°
Then, the sum of MON and LOM is equal to LON
∠MON + ∠LOM = ∠LON
8x-13 + 7x - 17 = 180
15x -30 = 180
15x = 180+30
15x =210
x =210/15
x = 14°
We want to find MON
∠MON=8x−13
∠MON=8(14)−13
∠MON=112−13
∠MON= 99°
