I need help! Jeff sold half of his comic book collection. Two years later he decides to start collecting again. After buying 12 comics, he now has a total of 35. Write and solve an equation for x as the number of comics Jeff had before he sold half of them.

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)

Yes. there is a constant ratio of number of calories to gram of protein.12/3=24/4=32/8=44/11=4

It’s either a or c as the answer.
