So first add all of the marbles together: 3+2+6+9=20
Because there are 20 marbles together, that would be your denominator.
All of the other numbers would be your numerator. So you would have:
3/20 green marbles
2/20 yellow marbles
6/20 blue marbles
9/20 red marbles
So your answer would be the probability of picking a red marble from the bag is 9/20 or 45%
Step-by-step explanation:
Let Number of senior citizen tickets
sold = x
Number of students tickets sold = 3.x
Number of adult tickets sold = 4 x 3x
= 12x
/* According to the problem given */
3x = x + 142
+ 3x – x = 142
2 x = 142
142 == 2
> x = 71
. Number adult tickets sold
= 12x
= 12 x 71
= 852
Answer: n + 2 = 2n
Step-by-step explanation:
sum = add
number and two = n, 2
twice the number = 2 x n
Answer:
Step-by-step explanation:
If A, B, and C are in the ratio of 2:3:5 and they are each getting some amount of money in that ratio, then to find the total amount of money they split is found in Ax + Bx + Cx and we need to solve for x. What we are told is that the smallest share = 210 and obviously A is the smallest share. Therefore,
2x = 210 and x = 105.
The total sum = 210 + 3(105) + 5(105) so
Total sum = 210 + 315 + 525
Total sum = 1050 and
C's share is 525 and
B's share is 315
B. is the answer I believe since most are not functions
