Which variable expression represents the word phrase? the sum of 12 and the quotient of 9 and a number 12−(9÷y) 9 + (12 ÷ y) 12 + (9 ÷ y) 12−9y

The answer to this problem is 12 + (9 ÷ y).

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)
