Answer:
1. 16.5
3. 12
Step-by-step explanation:
1. So, we need to figure out how 4 expanded to 12. To do that, divide 12/4.
12/4=3. Now, we got our growth factor. All we need to do now is multiply 3.5×3.
3.5×3=16.5, so 16.5=x.
3. now we have to figure out how 24 became 16. aka 16/24 because 16 has the x on its side. Simplify and get 2/3.
times 2/3×18 and you'll get 12.
12=x.
