Answer:
81
Step-by-step explanation:
Given total number of tests are 5
The grades earned by the students in the tests are 84 , 75 , 97 , 89
let the grade earned by the student in the fifth test be x.
Average=
The condition recquired is Average≥85
≥85
≥85
x≥81.
The least grade the student can earn in the last test so that average is not less than 85 is 81
34-12=22
the answer is:
If the outside is 34c and the inside is 12c then the answer is 22c, as you are taking off 12 from 34.
Although the terms might seem intimidating, this is a simple substitution problem.
X + Y = _______
Substitute the values of X and Y in terms of w
(7w^2 + 4w - 6) + (w^2 - 11w + 13) = ______
Now all you need to do is combine like terms (terms that have the same variables raised to the same power)
8w^2 - 7w + 7
Final Answer: 8w^2 - 7w + 7
