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

-8x + 8y + 3x - 8y = 8 - 18 - 5x = - 10 Correct option is D
Only two numbers less than 100 have a factor of 40: 40 (1 x 40) and 80 (2 x 40). Since 40 is a factor of both 40 and 80, 10 must also be a factor - indeed, 40 = 4 x 10 and 80 = 8 x 10.
0.9. The reason why is because the 5 brings the 8 to a 9.
Answer:
80
