8.34 is the product of 8.34
12x+15y=34
2(-6X+5Y)=3
12x+15y=34
-12x+10y=6 = 25y=40 25/40 =0.25 then you plug that back into any original equation and you get the x
Answer:
x=1, y=-1. (1, -1)
Step-by-step explanation:
2x-3y=5
x+2y=-1
---------------
2x-3y=5
-2(x+2y)=-2(-1)
-----------------------
2x-3y=5
-2x-4y=2
-------------
-7y=7
y=7/-7
y=-1
x+2(-1)=-1
x-2=-1
x=-1+2
x=1
Answer:
18
Step-by-step explanation:
7 - 5 = 2
triangle = bh/2
triangle = 2(3) / 2
triangle = 3
rect = bh
rect = 3 x 5
rect = 15
trapezoid = 15 + 3
trapezoid = 18
