I have 5 questions. Please try to answer as many as possible! It would be a big help. 1. Emma is 10 years old. She asked her father how old he is. Her father answered, "When you are my age, I will be 70." How old is Emma's father?

2. Kathy is 12 years old and Ben is 16 years old. How many years ago was Ben three times older than Kathy?

3. James's dog, Buddy, is 2 years older than Fluffy, the neighbor's cat. Three years ago, Buddy was three times older than Fluffy. How old are the cat and dog now?

4. John is two years younger than his sister, Annie. Last year, John was half Annie's age. How old and John and Annie now?

5. The sum of Ellie's and Genya's age is 60. In 6 years, Genya will be 8 times older than Ellie will be. How old is Ellie now?

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
