i do i figure out what grade i need to get on a midterm to get the final grade i want?

Question

i have my grade % for the 1st and 2nd quarters and semester grade is determined the 1st and 2nd quarter grades being worth 45% each and the final is the other 10%. can some one tell me hoe to set this problem up

Answer 1

If two 'quarter' tests plus a final determines the semester grade, where does the midterm enter in to the grade?

Answer 2

Final grade=1st quarter grade(.45) + 2nd quarter grade(.45) + .1x
where x=score on final exam

If you want to get a 90% as your final grade and you have a 95% for 1st quarter and 88% for 2nd quarter, your equation would look like this:

.90=.95(.45) + .88(.45) + .1x

.90=.42 + .39 + .1x

.90=.81 + .1x

.09=.1x

x=.9 or 90%

Answer 3

((1st quarter grade) x 0.45) + ((2nd quarter grade) x 0.45) + ((midterm grade) x 0.10) = grade you want

Substitute in the 1st and second quarter grades, as well as the grade you want and do some simple algebra to solve for the midterm grade. ta da!

Answer 4

that depends on the final grade you want and the grades you have so far.

Answer 5

your elementary is ninety*0.15 + a hundred*.4 + seventy 4*.2 + seventy six*.15 + (a hundred/one hundred twenty)*.a million this is seventy 9.78333 Your instruments have been form of confusing so in the event that they are in percents then I did it best. in the event that they are in factors, then there is little doubt which you failed.
