Answer:
x = -1
y = 2
Step-by-step explanation:
x + y = 1
y = -x + 1
y = -x + 1 (Multiply this by -1)
y = 3x +5
-y = x - 1
y = 3x +5
0 = 4x + 4
4x = -4
x = -1
x + y = 1
-1 + y = 1
y = 2
Answer:
7.4
Step-by-step explanation:
just divide it by 3.2
90=l+l+w+w
90=28+28+w+w
90=56+2w
34=2w
17=w
The width of the playground is 17.
The first one is < because if you have 5 part of 7, you have more parts than if you have 4 parts of 7, but it’s negative so it’s the opposite
