Which statements can be represented by this equation? Select three options. 2 n minus 9.2 = n + StartFraction 4 over 5 EndFraction
Twice a number minus nine and two-tenths is the same as the number plus four-fifths.
Nine point two decreased by double a number is the same as the number added to four-fifths.
Nine point two less than twice a number is equal to the number added to four-fifths.
Two times the difference of a number and nine and two-tenths is equal to the number plus four-fifths.
Double a number decreased by nine and two-tenths is the same as the sum of four-fifths and the number.

Options A,C and E.

Step-by-step explanation:

The given equation is

Let n be the unknown number, then

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

So, option A is correct.

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

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

So, option C is correct.

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

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

So, option E is correct.

Therefore, the correct options are A,C and E.

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
