Mathematics
1 answer:
Nadya [2.5K]3 years ago
4 0

Step-by-step explanation:

We have 3(x + 3) = 10 + 2(x - y).

=> 3x + 9 = 10 + 2x - y

=> x = 1 - y

=> y = 1 - x.

(Rewritting it as a mathematical statement is the 1st line)

nadya68 [22]

Answer:

84 is the highest possible course average

Step-by-step explanation:

Total number of examinations = 5

Average = sum of scores in each examination/total number of examinations

Let the score for the last examination be x.

Average = (66+78+94+83+x)/5 = y

5y = 321+x

x = 5y -321

If y = 6, x = 5×6 -321 =-291.the student cannot score -291

If y = 80, x = 5×80 -321 =79.he can still score higher

If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.

If y= 100

The average cannot be 100 as student cannot score 179(maximum score is 100)
