Answer:
C
Step-by-step explanation:
because the limo charges 30 and 4 per person and the person is x . The other limo automatically charges 70 plus 2 per person which is x hence 30+4x=70+2x
The first thing to do is to calculate how many ways you can choose 3 people from a set of eight. In order to do this, we need to use the attached formula.
(The letter 'n' stands for the entire set and 'r' stands for the number of objects we wish to choose.)
So we wish to choose 3 people ('r') form a set of 8 ('n')
combinations = n! / r! * (n - r)!
combinations = 8 ! / (3! * 5!)
combinations = 8 * 7 * 6 * 5! / (3!) * (5!)
combinations = 8 * 7 * 6 / 3 * 2
combinations = 56
Now of those 56 combinations, the 3 people can finish in 6 different ways.
For example, persons A, B and C could finish
ABC or ACB or BAC or BCA or CAB or CBA
So to get the TOTAL combinations we multiply 56 * 6 which equals
336 so the answer is (a)
Alex walks 3 miles per hour. So if he need to find how much time he will need to get to school, you just have to divide the distance from school by his miles per hour. 2.25/3 which equals 0.75. 0.75 is the percent of an hour he needs to walk 2.25 miles. To find the total minutes, multiply 0.75 by 60 to get 45. Alex takes 45 minutes to walk to school.
So here is the answer. Given that in 3 bags or trail mix made 18 snack packs, this would mean that in every bag, she can make 6 snack packs because 18 divided by 3 is 6. Hope this is the answer that you are looking for. Have a great day ahead!
Pretty sure it’s D and F because if you set (x-4)=0, x is 4 and if you set (x+7)=0, x is -7
