Hey mate here is your answer.
➛ 6(x-2) = 4(x+3)
➛ 6x-12 = 4x + 12
➛ 6x - 4x = 12 + 12
➛ 2x = 24
➛ x = 
⛬ x = 12
First, you would need to determine how many questions he got correct.
30 - 12 = 18
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Now, you would cross multiply.
30x = 1,800
The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x =
60Ahmad got 60% of the questions correct. I hope this helps!
Well, a bisector is a ray that cuts the angle in half, which means that both of the angles are now the same. So, we get:
8x - 1 = 4x + 3
4x = 4
x = 1
Earnings For The First Job
monthly pay =262 × 4
= 1048
Yearly pay = 1048 × 12
= 12 576
Earnings for the second job
yearly pay = 16 200
Difference for the two jobs
16200 - 12576 = 3624
Answer = The second job that pays $16200 has a better from the first job by 3624
