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.
B. -5
The two straight lines are parallel, and the angles are at the same places (below and to the right of the diagonal line). The two angles must be the same, and to get 65 from x + 70, x has to be -5.
2.67 - 1.84 = 0.83
Tina added 0.83 liters of olive oil.
Triangle angles always add up to 180 degrees.
So what you’ll need to do is add up all the angles and set them equal to 180. And then solve for x
4x+3x+2x=180 | Add up all values
9x=180 | Divide 180 by 9
x=20 | There’s your answer
