Answer:
A
Step-by-step explanation:
Just switch the orders around where it is going from the highest power to the lowest power
X + 0.5 + 3x - 2 = 3x + 1.5
X= 3.5
Putting the all x on the right side and distributing all the numbers on the left side
So if 6 out of 40 are incorrect, 40-6= 36 must be correct.
In order to gain percentage you do proportions.
36/40 = x/100.
Multiply 36 times 100 then divide by 40, which is 90.
The answer is 90%.
90% of the questions he got were correct.
