Hello thee i hope you are having good day :) Your Question: 15-foot piece of string is cut into two pieces so that the longer piece is 3 feet longer than twice the shorter piece. If the shorter piece is x feet long, find the lengths of both pieces.
so firstly you would do L = 3 + 2x S = x X + (3 + 2x) = 15 X + 3 + 2x = 15
3x + 3 = 15 then you would take away that 3x = 15 - 3 this would equal 12 so x = 4 and then add it 3+ 2x = 3+2 (4) = 3 + 8 = 11 Short piece is 4 feet Long piece is 11 feet.
Hopefully that helps you ❤
What we need to do is divide the total prize by the number of units, that is by 9:
we know this because 9 of those pieces, or 9p is equal to 54.90
so the right equation is <span>B. 9p= 54.90
(another possibility would be p=54.90/9)</span>
Maybe try 1 I cannot figure it out
