Answer:
k-n+1
Step-by-step explanation:
How many numbers are written from n to k
Lets look at a smaller example with real number
Lets go from 3 to 8
3 4 5 6 7 8
There are 6 numbers
We take 8 -3 = 5, but we include the number 3 so we add it back in +1
5+1 =6
Lets look at a larger example
2 to 11
2,3,4,5,6,7,8,9,10,11
There are 10 numbers
11-2 =9 but we have to add back in the first number
9+1 =10
Now we are going from n to k
k-n = k-n, but we have to add back in the first number
k-n+1
Hi!
Whatever we do to the inequality, we have to do it to both sides.
Subtract 14 from both sides
14 - 14 - 3x < -1 - 14
-3x < -15
Divide by -3 on both sides
-3x/-3 < -15/-3
x < 5
Because we divided by a negative number, the equality sign flips.
x > 5
^ the answer
Hope this helps! :)
You have -4,-3,-2, that is a 3 out of a total of 21 points or numbers on the number line. 3/21 is reduces to 1/7.
3 goes into 21 , 7 times. That is why it reduces to 1/7.
