Ateacher 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 to miguel. he gave twice as many to kira as miguel. how many fish did each student get?

x+2x+4x=28

7x=28

/7 both sides

x=4

2x=8

4x=16

Alaina: 4 fish

Miguel: 8 fish

Kira: 16 fish

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

sine
