Answer:I would add 3x on both sides because it would allow you to have a positive variable saving you time and effort.
Step-by-step explanation:7=7x-9
The length of one of the sides of the larger pentagon is 24 cm. The length of one of the sides of the smaller pentagon is 8 cm.
÷![8=3](https://tex.z-dn.net/?f=8%3D3)
So, if the larger pentagon is 3x the size of the smaller pentagon, we can find the area of the smaller pentagon by dividing the area of the larger pentagon by 3.
÷![3=45](https://tex.z-dn.net/?f=3%3D45)
The area of the smaller pentagon is 45in²

Answer:
Your first step in solving the system would be to substitute the value of a variable into one of the equations
Step-by-step explanation:
We know that x = 2y + 2 and y = -1/3x + 4, so we could insert one of these values as the variable in one of the equations
If we were to insert -1/3x + 4 for y, our new equation would be:
x = 2(-1/3x + 4) + 2 (as you can see, the value of y was inserted into the equation)
Answer:
It's 15°
Step-by-step explanation:
BC+60°+85°+200° =360°
BC+345°=360°
BC=360°-345°
Bc=15°
