Answer:
x=6 y=-9
Step-by-step explanation:
- Layer the equations on each other as you would in a subtraction problem:
8x + 2y=30
7x + 2y=24
- Subtract the equation just like you would normally. This should leave 1x=6 or x=6.
- Now that you have your x value, plug it in as x for one of the equations. For the 2nd equation, this leaves:
42+2y=24 then
2y=-18 then
y=-9
- Double check your y value by plugging x=6 into the first equation. This should also leave y=-9.

Answer:
36.6 cm
Step-by-step explanation:
We have the rectangle upright and the rectangle on its side.
Counting the sides starting from the lower left vertex and going clockwise.
7 + 4.3 + (7 - 4.3) + 7 + 4.3 + 7 + 4.3
= 7 + 4.3 + 2.7 + 7 + 4.3 + 7 + 4.3
= 36.6 cm
Answer:
