A teacher is having three students take care of 28 goldfish during the summer. He gave some of them to Alaina. Then he gave twice as many Miguel. He gave twice as many to Kira as he gave to Miguel. How many fish did each student get?

Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16

Step-by-step explanation:

Let the number he gave to Alaina be x. Now, we know he gave twice as many to Miguel. Amount received by Miguel is 2x.

He gave Kira 2 times what he gave Miguel, that is 2x * 2 = 4x

Addition of all these equals 28. We now get x

4x + 2x + x = 28

7x = 28

X = 28/7

x = 4

Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
