Answer:
I think x is 1/2.
Step-by-step explanation:
Because the triangles are similar, you can set 9x + 1 = x + 5. Subtract x and 1 from both sides to get 8x = 4. divide and you get x = 1/2.
(double check me though.)

The outside number 11 will be multiplied by EVERY term inside the parenthesis. This is called "distribution".
We have the outside number 11 multiplied by the first term y to get 11*y = 11y
Then we repeat the same steps but now for the other term -2 to get 11*(-2) = -22
So 11(y-2) will become 11y-22
Final Answer: choice D) 11y-22
Lets focus on what we know first. Natalie can pick 135 Berries in 15 minutes. Lets find out how many berries she can pick per minute.
In order to do so, We have to divide 135 by 15.
135/15=9
This means that Natalie can pick 9 berries per minute. Given that we want her to pick 486, we will need to divide that number by 9 berries to find out how many minutes it will take to get her to that number of berries.
486/9=54
This means that it will take Natalie 54 minutes in order to pick 486 berries.
