By rewriting the weights in decimal form and applying them to the correspondent percentages, we will see that the final grade is 92.8%.
<h3>
What is Jore's final math grade?</h3>
The final grade will be given by:
G = a₁*x₁ + a₂*x₂ + ...
Where the values "a" are the weights, and the values "x" are the averages of Jeorge.
We know that the weights are:
- 30% on Quizzes.
- 10% on homework
- 40% on unit test.
- 20% on the final exam.
Then we can write the weights in decimal form:
a₁ = 0.3
a₂ = 0.1
a₃ = 0.4
a₄ = 0.2
And the scores are:
- 92% on quizzes.
- 98% on homework
- 91% on unit tests
- 95% on final exam.
So the final math grade will be:
G = 0.3*92 + 0.1*98 + 0.4*91 + 0.2*95 = 92.8%

Answer:
First in your head multiply 8 by 7. this equals 56. now multiply 8 by 9 twice since there is two 9's. now you have two 72's. Add the 2's together from both 72's. now your numbers are 70, 70, 56 and 4. Add the four to your 5 which is now 96. split 96 between the 70's. not dividing just the two numbers. now you have 79, and 76. put together your numbers and your answer is 7976.

Answer:
-204
Step-by-step explanation:
(3−5)(34)(3)
=−204
2(3m-6+3m)=2m+2-4m
6m-12+6m=2m+2-4m
12m-12=-2m+2
14m-12=2
14m=14
m=1
