What we have to do is to find the largest common divisor of the two numbers: 12 and 30. It must be at least 2, since they're both even, and at least 3 since both are divisible by 3, so that means that it it also must be at least 6 (2*3=6; if they're divisible by 2 and 3, they must be both divisible by 6).
But they have no bigger divisor than this.
So that means that the number of groups will be 6 (both groups can be divided into 6). It will have 2 (12/6=2) newcomers and 5 (30/6=5) advanced swimmers.
18<x is the answer you are looking for. Glad to help.
Answer:
both are wrong
Step-by-step explanation:
raj's mistake: he did not multiply -2 by -5a/4
antonia's mistake: she went from -4a/4 to a which is wrong because -4/4 is -1.
Nina used 2 cups. The correct answer is B. Use this formula;
lets assume y is the amount of ounces she used. Lets assume x is the amount of cups she used.
y = x(8)
Replace y with 16.
16 = x(8)
Divide by 8.
2 = x
Thus, 2 cups.
