What is 2 thirds plus 3 fourths

Answers

2/3 + 3/4. To solve this equation sir you must find a common denominator. The lowest common denominator is 12. It will equal 17/12 or 1 and 5/10.

In order to find this you need to find a common denominator. 2/3 and 3/4 common denominator would be 12 and so what you do to the bottom you must do to the top. 2x4 is 8 and 3x3 is 9. that would make 8/12 and 9/12. 8 plus nine is 17 and 12 stays there so the answer is 17/12 which equals 1 and 5/10.

Marge has saved $350 toward the cost of her vacation. The vacation will cost $1,750. What percent of the cost of the vacation has Marge saved?

Answers

350x5=1750
100/5=20
converts to 20%

Final answer:

Marge has saved 20% of the total cost of her vacation.

Explanation:

Marge's vacation savings can be calculated as a percentage of the total cost, using the formula: (Amount Saved / Total Cost) * 100. In this case, with a total vacation cost of $1,750 and Marge having saved $350, the calculation is ($350 / $1,750) * 100. When computed, it reveals that Marge has successfully saved 20% of the total vacation expense. This means that she has allocated a fifth of the overall cost, demonstrating a commendable financial preparation for her upcoming getaway. Such conscientious savings practices contribute to a more relaxed and enjoyable vacation experience, as Marge has set aside a significant portion of the required funds.

Answers

Heres my solution
Plug in x and y into your first equation.
So it ends up being 5(2)^2 - 2(3)
Then solve.
The answer is 14...
I have a question though - > Does your statement equal 14? Is there something else you are missing?
If so, then could you write what it equals.
If it is 14, then you can write it that way as a true statement.
