This year, the sum of your ages is 2k - y. Next year, the sum of your ages will be 2k - y + 2, and the difference in your ages will remain y.
Explanation:If you are k years old and your daughter is y years younger, then your daughter's age is 'k - y'. The sum of your current ages is k + (k - y), which simplifies to 2k - y.
Next year, both of you will be one year older. Therefore, the sum of your ages next year would be '(k + 1) + (k - y + 1)', which simplifies to 2k - y + 2.
The difference in your ages next year would still be 'y' because the ages increase uniformly and the difference between your ages doesn't change.

3. At a bargain store, Tanya bought 3 items that each cost the same amount. Tony bought 4 items that each cost the same amount, but each was $2.25 less than the items that Tanya bought. Both Tanya and Tony paid the same amount of money. What was the individual cost of each person's items? (a) Write an equation. Let x represent the cost of one of Tanya's items. (b) Solve the equation. Show your work. (c) Check your solution. Show your work. (d) State the solution in complete sentences. Answer:
3x = 4(x-2.25)
3x = 4x-9
add 9 to both sides
3x+9 =4x
subtract 3 x from each side
x=9
Tonya's items were $9 each
Tony's items were 9-2.25 = 6.75 each

Hayley begins solving this problem by combining like terms. 3x + 5x = 10 Which problem requires the same strategy (combining like terms)? A) 5x=20 B) 3(x + 5) = 20 C) x ÷ 4= 30 D) 3x - 2x = 10
Answer:
D) 3x - 2x = 10
Explanation:
To combine like terms, you add or subtract terms that have the same variables and exponents. In the problem we are given, 3x and 5x are like terms; we would add them together and then continue solving.
In choice A, there are no like terms to combine.
In choice B, we would use the distributive property; after that, there are no like terms to combine.
In choice C, we would cancel the 4; there are no like terms to combine.
Choice D has two like terms, 3x and 2x. We would subtract them and then continue solving.
