Answer:

n = -10

Step-by-step explanation:

-66 = -9n + 16n + 4

1. I started by subtracting 4 on both sides of the equation this gives you -70 = -9n + 16n

2. I then combined the like terms 16n and -9n on the right side of the equation. We do this by subtracting 9n from 16n. Which gives you -70 = 7n

3. We then divide both sides by 7 in order to get -10 = n

This gives you your final answer of n = -10

If the average (arithmetic mean) of five distinct positive integers is 10, what is the difference between the largest possible v
Arte-miy333 [17]

Answer:

The difference between the largest possible value of the greatest integer and the least possible value of the greatest of the five integers = 4

Step-by-step explanation:

<u>Step 1</u>:-

let 'x' be the number

The sequence of arithmetic progression of distinct positive integers

x , x+1 , x+2 , x+3 , x+4

Given the average of five distinct positive integers is 10

\frac{x+x+1+x+2+x+3+x+4}{5} = 10

on simplification , and cross multiplication , we get

5x +10 = 5 X10

5x +10 =50

subtracting'10' on both sides, we get

5x +10 - 10 = 50 -10

5x =40

dividing '5' on both sides, we get

x = 8

The number is '8'

Step 2:-

Now the arithmetic sequence of five numbers are

x , x+1 , x+2 , x+3 , x+4

8 , 9, 10 , 11 , 12

In this sequence is smallest number is '8' and

The largest number is '12'

the difference between the largest possible value of the greatest integer and the least possible value of the greatest of the five integers

= largest possible value - least possible value

= 12 - 8 =4

<u>Final answer</u> = 4
