Answer:
A. 2(x + 9) = 8
Step-by-step explanation:
To solve this problem, we proceed as follows:
- We call "x" the number picked up by Amy:
- Amy then adds 9 to this number, so we get:
- Then, we multiply this sum by 2, so we get:
- Finally, Amy says that this number is equal to 8:
So the correct equation is
A. 2(x + 9) = 8
We can even solve it to find the number. We get:
