4. Rita started the day with rapps. Then she deleted
5 apps and still had twice
as many apps as Cora has.
Write an equation that
represents the number
of
apps each girl has.

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)
