<u>Explanation:</u>
"4 times as many" means that Beth has 4n more quarters than Michael. When we are comparing Beth and Michael, we obtain the equation "B = 4n", where B is the number of quarters Beth has and m is the number of quarters Michael has. Let's find out how many quarters Michael has.
<u>We know that:</u>
<u>Solution:</u>
- B = 4n
- => 16 = 4n
- => n = 16/4
- => n = 4
Hence, Michael has 4 quarters.
Bro- basically so the first option a- right? So a is 4-8-12-16. And B is just that times two so the third option down
The first area is simply the are of the innermost circle, so we have
Then, the region inside circle 2 and outside circle 1 is the difference between the areas of these circles:
By the same logic, we have
So, the ratios are
And similarly
We need to have some choices to give you the answer
