Peaches are being sold for $2 per pound. if x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?

a) the values of both x and y can be any real number.
b) the values of both x and y will be real numbers greater than or equal to 0.
c) the value of x can be any real number, but the value of y will always be a real number greater than or equal to 0.
d) the value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
