Answer:
Equation to find area: l*w
Unknown measurement: w = 4,700/94 = 50
Equation to find perimeter: l+l+w+w or l*2+w*2
Perimeter: 288
Hope this helps :)
Systems of linear equations can only have 0, 1, or an infinite number of solutions. The two lines can't intersect twice, so the correct answer is that the system has one solution.
5x+2y=20 when x=3/10 is:
5(3/10)+2y=20
15/10+2y=20
1.5+2y=20
2y=18.5
y=9.25
