Question

Which statements can be represented by this equation? Select three options.

2n-9.2 =n+4/5

Answer 1

1 Twice a number minus nine and two-tenths is the same as the number plus four-fifths.

3 Nine point two less than twice a number is equal to the number added to four-fifths.

5 Double a number decreased by nine and two-tenths is the same as the sum of four-fifths and the number.

Explanation:

Answer 2

1, 3, 5

Explanation:

Let the number be n

1.Twice a number minus nine and two tenths is the same as the number plus four fifths.

Twice a number is 2n. nine and two tenth = 9.2. Therefore twice a number minus nine and two tenths = 2n - 9.2. the number plus four fifths = n + 4/5

The resulting equation is 2n-9.2 =n+4/5

2.Nine point two decreased by double a number is the same as the number added to four fifths.

Nine point two = 9.2, double a number = 2n. Therefore, Nine point two decreased by double a number is 9.2 - 2n

The resulting equation gives 9.2 - 2n = n + 4/5

3.Nine point two less than twice a number is equal to the number added to four fifths.

Nine point two = 9.2, twice a number = 2n. Therefore Nine point two less than twice a number = 2n - 9.2

The resulting equation is 2n-9.2 =n+4/5

4.Two times the difference of a number and nine and two tenths is equal to the number plus four fifths.

The difference of a number and nine and two tenths is given by n - 9.2. Therefore, Two times the difference of a number and nine and two tenths is 2(n - 9.2).

The resulting equation is 2(n - 9.2) = n + 4/5

5.Double a number decreased by nine and two tenths is the same as the sum of four fifths and the number.

Double a number decreased by nine and two tenths is 2n - 9.2

The resulting equation is 2n-9.2 =n+4/5
