Which statements can be represented by this equation? 2n-9.2=n+4/5 Check all that apply1.Twice a number minus nine and two tenths is the same as the number plus four fifths.2.Nine point two decreased by double a number is the same as the number added to four fifths.3.Nine point two less than twice a number is equal to the number added to four fifths.4.Two times the difference of a number and nine and two tenths is equal to the number plus four fifths.5.Double a number decreased by nine and two tenths is the same as the sum of four fifths and the number.
Question
Answer:
2n - 9.2 = n + 4/51. twice a number minus nine and two tenths is the same as the number plus four fifths. <=== yes, this one works
2. nine point two decreased by double a number....nope, this one doesnt work...because, starting off, the set up would be : 9.2 - 2n
3. nine point two less then twice a number is equal to the number added to four fifths <== this one works
4. two times the difference of a number and nine and two tenths....nope, this one does not work....it would start off being set up like : 2(n - 9 2/10)
5. Double a number decreased by nine and two tenths is the same as the sum of four fifths and the number <== this one works
so the ones that can be represented by the equation are :1,3,5
