Answer:
x = 40
Step-by-step explanation:
The figure shows two similar triangles. Thus, the side lengths of similar triangles are proportional to each other. Therefore:
![\frac{24}{24 - 15} = \frac{x}{x - 25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B24%7D%7B24%20-%2015%7D%20%3D%20%5Cfrac%7Bx%7D%7Bx%20-%2025%7D%20)
![\frac{24}{9} = \frac{x}{x - 25}](https://tex.z-dn.net/?f=%20%5Cfrac%7B24%7D%7B9%7D%20%3D%20%5Cfrac%7Bx%7D%7Bx%20-%2025%7D%20)
Cross multiply
![24(x - 25) = 9(x)](https://tex.z-dn.net/?f=%2024%28x%20-%2025%29%20%3D%209%28x%29%20)
![24x - 600 = 9x](https://tex.z-dn.net/?f=%2024x%20-%20600%20%3D%209x%20)
Subtract 24x from each side
![- 600 = 9x - 24x](https://tex.z-dn.net/?f=%20-%20600%20%3D%209x%20-%2024x%20)
![- 600 = -15x](https://tex.z-dn.net/?f=%20-%20600%20%3D%20-15x%20)
Divide both sides by -15
![40 = x](https://tex.z-dn.net/?f=%2040%20%3D%20x%20)
x = 40
Answer:
Step-by-step explanation:
x = 55
y = 60
a = 14
did it in my copy but it took too long to upload so i gave up. sry
You divide the numerator by the denominator
Answer:
Yes.
Step-by-step explanation:
A linear equation is of the form y = mx + b.
2x = 4y
y = 2x/4
y = 0.5x
so it is linear.
