Myra has a 17- foot roll of crepe paper to make 8 streamers to decorate for a party. how long will each streamer be if she cuts the roll into equal pieces?

2.125. right? if you divided 17 by 8 you get 2.125

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)
