So, if this rate remains constant then 1 plate will be washed in $\frac{24}{8} = 3$ minutes.

Again, it is given that, Amelia bakes 12 cookies in 60 minutes.

So, if this rate also remains constant then she will bake 1 cookie in $\frac{60}{12} = 5$ minutes. ( Answer )

When you solve a square root problem, can you just divide it by 2? for example in this picture can you do 25 divided by 2?

Answer:

Step-by-step explanation:

When you square a number, you chose a number and multiplying itself. If you did the square root of 25, you would get 5. However if you divided 25 by 2, you would get 12.5 which is NOT the square root.
