When 3 less than the square of a number n is multiplied by 2,the result is 122. if n > 0, what is the value of n?

          The value of n is:

                           n=8

Let n be a number.

Now we are given a statement that:

When 3 less than the square of a number n is multiplied by 2,the result is 122.

3 less than a square of a number n is:  n²-3.

Now when this number is multiplied by 2 we get:

2(n²-3)

Now this expression is equal to 122.

Hence,

on dividing both side by 2 we get:

( Since n=-8 is not possible as n>0 )

                      Hence, the value is:

                                 8

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
