when 3 is subtracted from one third of a number n the result is less than 6. which inequality and solution represents this situation.

1/3n-3<6

Step-by-step explanation:

One third of a number: 1/3

3 is subtracted from 1/3 of a number n: 1/3n -3

Result is less than 6: less is represented with the symbol <. So, the result of the expression 1/3n-3 is less (<) than 6.

The final expression:

1/3n-3<6

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

f is the midpoint of
