Anumber x divided by 3 is at most 5.

"At most" refers to less than or equal to (≤).
This is because "at most" means no more than, must be less than, and can be equal to.
As an inequality, this would be written as x / 3 ≤ 5.
This means that x divided by 3 is less than or equal to (at most) 5.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
