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

Y = 2X is the expression which describes the value of X and Y.

Step-by-step explanation:

Peaches are being sold at the rate = $2 per pound

If X represents the number of pounds of peaches purchased then the total cost of the peaches = 2X

Total cost of the peaches is represented by Y, then the expression will be

Y = 2X

Therefore, expression which shows the relation between X and Y is

Y = 2X

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
