the reason you flip the sign is because you multiplied with a negative number. always flip sign if the number you are either multiplying or dividing by is a negative. if it is positive then keep the sign the way it is.
Let, the two-digit number = xy
It is given that, xy = x + y²
Then, number which obey the rule is 89.
Check: 8 + 9² = 8 + 81 = 89 [ Itself ]

Answer:
There were 84 students in 6th grade, 68 in 7th grade, and 90 in 8th grade.
Step-by-step explanation:
Given that Elk middle school has 264 students, and there are 84 students in the eighth grade, and there are 22 fewer seventh-grade students than sixth-grade students, to determine how many students there are in each grade, the following calculation must be performed:
(264 - 84) / 2) - 22 = X
(180/2) - 22 = X
90 - 22 = X
68 = X
6th grade = 84
7th grade = 68
8th grade = 90
Therefore, there were 84 students in 6th grade, 68 in 7th grade, and 90 in 8th grade.
All you have to do is multiply 2.3 by 13 together to get 29.9. Then you would subtract that by the total volume which would get 107.64. That's the width.
