The sum of twice a number and a larger number is 145. The difference between the numbers is 55. Let x represent the smaller numb
er and y represent the larger number. Which equations represent the situation? Check all that apply. A. x-y=55
B. 2(x+y)=145
C. 2x+y=145
D. y-x=55
E. y=x+55
sum (addition) of twice a number (2x) and larger number (y) is (=) 145 2x+y=145
difference between them is 55 (y is bigger so it would be x is subtracted from y) y-x=55
so the equations are
2x+y=145 and y-x=55
we could add x to both sides in the 2nd equation to obtain y=x+55, but that doesn't really represent that the difference is 55, though they are the same euation
5000 is the amount being put in the accounts, the constant. You add 1 to the decimal amounts because 0.3x represents a decrease and these are increasing. Do that to both and that's your equation.
