Answer:
The student must get at least 86 in the next text in order to get an upper A average.
Step-by-step explanation:
The scores in the three tests are: 91, 94 and 89
The average score here is = 91 (rounded off to nearest whole number)
In order to get an Upper A average after tackling the next test, the students total score in the four tests must be 90 × 4 = 360
Let's say the student scores x in the fourth test.
Then; 91 + 94 + 89 + x ≥ 360
274 + x ≥ 360
x ≥ 360 - 274
x ≥ 86
6k+234
Step-by-Step Explanation:
Add 9, 3, 212, 3, and 7. You get 234. You can't change 6k because the variable, so you end up with 6k+234.
