Answer:
200
Step-by-step explanation:
160/80 is 2. 2 times 100 is 200
Answer: 2.25
Divide the corresponding values. You'll divide figure 2's length over figure 1's corresponding length. So 18/8 = 2.25
This means each side of figure 2 is 2.25 times larger than the corresponding side for figure 1
For this case, the first thing we must do is define a variable.
We have then:
x: number of weeks
y: amount of cereal that Melanie eats
We now write the function that models the problem:

Then, for 5 weeks we have:
Answer:
A model that best represents the number of pounds of cereal she eats is:
For 5 weeks we have:
I think the answer is 1.06666666667
I assume you mean to ask how to find the sum of the seven terms?
You have



...

So the sum is

You know that

and

, so the sum is equal to
