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
You have to substitute the x so since x=7 you have to do 5x7 which is 35 then you add the 2 making 37. Just tell me if you have any questions
The incorrect rounding for 53.864 is 53.87

Solution is on the picture.
I assume you are solving for x
<span>x*24-34+56 = 0
Start by isolating the term with x in it on one side of the equation.
To do this, we can subtract 56 and add 34 to both sides.
24x = -22
Divide both sides by 24 to complete the problem.
x= -22/24</span>
