6. 63(Could have counted wrong. Mode is the number that appears the most in a set of data)
7. Couldn't solve sorry!
Answer:
12x
Step-by-step explanation:
![12x(8x - 20) \div 4(2x - 5) \\ \\ = 12x \times 4(2x - 5) \div 4(2x - 5) \\ \\ = \frac{12x \times \cancel{ 4(2x - 5)}}{\cancel{ 4(2x - 5)}} \\ \\ = 12x](https://tex.z-dn.net/?f=12x%288x%20-%2020%29%20%5Cdiv%204%282x%20-%205%29%20%5C%5C%20%20%5C%5C%20%20%3D%2012x%20%20%5Ctimes%204%282x%20-%205%29%20%5Cdiv%204%282x%20-%205%29%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B12x%20%5Ctimes%20%5Ccancel%7B%204%282x%20-%205%29%7D%7D%7B%5Ccancel%7B%204%282x%20-%205%29%7D%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%2012x)
Answer:
1/2
Step-by-step explanation:
Because the solid triangle results in a smaller dashed triangle after the dilation, its scale factor will be a fraction. The length of the top side is 2 on the dashed triangle. It corresponds to the top side of the solid triangle which is 4.
2/4 = 1/2
The scale factor is 1/2 the size.
