q6: x=-23/5, y=4/5
q7: x=-4/5 y=0
q8: x=6, y=4
Answer:
D- HM
Step-by-step explanation:
A ray has one point and one side that goes on forever. We see this expressed with HM
HK is a line
HM is a ray
Let the width of the room be = x
Length of the room = 3x, Since it is three times as wide
Perimeter = 80m
Perimeter = 2*(L + W) = 2*(3x + x) = 80
2*(3x + x) = 80
2*(4x) = 80
8x = 80 Divide both sides by 8
x = 80/8
x = 10, But length = 3x, = 3*10 = 30
Length = 30m
Answer:
there is no way that is an actual question
Step-by-step explanation:
The answer is -5.
Steps:
1. I multiplied the top equation by 2 and the bottom equation by 3 and then added them together.
2. 24x=72 is what you should have now. I divided each side by 24 to get x=3.
3. I plugged 3 in for x in one of the equations to get y=-8.
4. -8+3=-5.
