I think the answer is 9
It's a smaller version of the other figure.
21/3=7
27/3=9
The first number is 27 and the second number is 45 so the ratio would be 27;45
Answer:
81.0
Step-by-step explanation:
The tenth is the decimal directly to the right of the period (.) Since the next number to the right is 1, you would round down, which is 0.
Multiply 9 by 2a and 2, and you get 18a + 18. Another equivalent expression would be 18(a+1), which you can get by factoring the above answer.
