triangles=3x4/2=6

smaller rectangle=8.6x3=25.8

medium rectangle=8.6x5=43

large rectangle=8.6x4=34.4

Which statements are true about the ordered pair (2, 3) and the system of equations?

vlabodo [156]

3x + 4y = 18......(2,3)
3(2) + 4(3) = 18
6 + 12 = 18
18 = 18...correct

2x - 2y = 2....(2,3)
2(2) - 2(3) = 2
4 - 6 = 2
-2 = 2...incorrect

when (2,3) is subbed into equation 1, it is true
when (2,3) is subbed into the second equation, it is false
the ordered pair (2,3) is not a solution to the system of linear equations
