Answer:
B
Step-by-step explanation:
To solve this, we use ratio.
Firstly, we need to know the number of hours traveled. The total number of hours traveled = x+y
Ratio of this used by high speed train = x/(x +y).
Total distance traveled before they meet = [x/(x + y)] × z
For low speed train = [y/(x + y)] × z.
The difference would be distance by high speed train - distance by low speed train.
= z [ (x - y)/x + y)]
Mean 35.714 Med 38 Mode 44
Step-by-step explanation:
new arrange from lowest to largest numbers
22 27 35 38 40 44 44
mean = plus of all number/ number
= (22+27+35+38+40+44+44)/7
= 35.714
Median = the central value
= 38
Mode = the most frequency
= 44 (2 numbers)
Answer:
x=2
Step-by-step explanation:
x^2+10x+24=0
12x=24=0
12x=24
x=2
My math is rusty so this may not be the right answer.
You first multiply 6 and 8 to see how many people are put in the vans without rented a van. This would equal 48. You then subtract 48 from 59 to see how many people still need to be in a van. This would leave you with 11 people. Then you divide 8 from 11 to get 1 3/8. This means you need 2 vans to fit everyone.

Answer:
- common denominator: (x² -4)
- simplified complex fraction: (2x +1)/(9 -2x)
Step-by-step explanation:
It is helpful to remember the factoring of the difference of squares:
a² -b² = (a -b)(a +b)
__
Your denominator of (x² -4) factors as (x -2)(x +2). You will note that one of these factors is the same as the denominator in the other fraction.
