I think that the answer is C
Answer:
Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42
Step-by-step explanation:
Since we need to find the number of ways they could enter first, second and third place, (I can't demonstrate, but you should get the idea) take 8, 7 and 6 and multiply them, 5-1 we don't need, we just need 8, 7, and 6, multiply those three numbers and you get 336, there you go, 336 ways to organize all 8 girls in first, second and third place, hope this helps
Answer:
-2 = x
Step-by-step explanation:
4(1-x)+3x = -2(x+1) Distribute
4 - 4x + 3x = -2x -2 Combine Like Terms (On the same sides of the equal sign)
4 -x = -2x -2 Combine Like Terms (On different sides of the equal sign)
4 = -3x - 2 Solve
6 = -3x
-2 = x
