Answer:
Clearly from 1 to 15 we can only have the sum 6,9,12 and 15 to be divisible by 3.
Now meaning we have 4! ( 4 factorial) which implies 4x3x2x1= 24 .
We have 24 ways to pick distinct integers that are divisible by 3.
Step-by-step explanation:
The first thing you need to do is to look for numbers that are divisible by 3. Then you take its factorial
Answer:
448
Step-by-step explanation:
320/5 is 64 miles per hour
64*7 is 448
she will travel 448 miles in 7 hours
The equation that you should use to solve this is (13 + 1/4) - (6 + 2/3) = 6 and 7/12
Answer:
Step-by-step explanation:
If you meant to type x+1<21, then we simplify this inequality by subtracting 1 from both sides, ending up with x < 20.
I do not recognize what your "4" represents.
