Answer:
so the question is very interesting and the answer is 12 × 15 so the answer is 180 rolls of ribbons
2x+7=?
X=6
2(6)+7=
12+7=19
In six years, the tree will be 19ft
2x+7=44
Minus seven on both sides
2x=37
Divide two from both sides
X=18.5
Thus, it will take 18 and a half years for the tree to reach 44ft
To solve this just put a 1 over the 15. So it would be 12/7 + 15/1 which is 16 5/7.
