Notice that the second row is half the first, so the rows are dependent. This means there are infinitely many solutions to the system.
First it would be 42/6 and 48/6
So the first flag would be 7 feet and the second would be 8 feet long
7x+3(4x-8)=109
7x+12x-24=109
19x-24=109
19x=109+24
19x=133
X=133÷19
X=7
20 pounds of sand will be required to cover a sandbox with a W of 8 and a L or 10.
To solve this question, first we calculate the area of the sandbox (A=LW)(8*10=80). If our sandbox requires 80 square feet of sand, then all we need to do is divide our area by the amount of square feet one pound of sand covers. (80/4=20). This means that it would require 20 pounds of sand to cover our 80 square foot sandbox.
