If the test is a major grade ( 60% of final grade) then around 73-75 but if the grade is worth a daily grade (40% of final grade) 78-82
Answer is 285
Reason
When you divide by a fraction, you flip the fraction and multiply
So 190 divided by 2/3 becomes 190 x 3/2
Factor 190 x 3/2, multiply across
190 x 3 = 570 then
570 divided by 2 = 285
Here the solution in in picture.
-2 sqrt (20) -sqrt(125)
-2 sqrt(4*5) - sqrt(25*5)
-2 sqrt(4)sqrt(5) -sqrt(25)sqrt(5)
-2 *2*sqrt(5) -5sqrt(5)
-4sqrt(5) -5sqrt(5)
-8sqrt(5)
