Question

The table shows how women’s shoe sizes in the United Kingdom compare to women’s shoe sizes in the United States.

a. Write a linear equation to determine the U.S. size y if you are given the U.K. size x.

b. What would be the U.S. shoe size for a woman who wears a U.K. size 7.5

Answer 1

Answer:

A: Y = X + 2.5

B: 10

Step-by-step explanation:

A: To form the equation you have to use one of the numbers in X (U.k Size) for this example we'll use 3 and to form the equation you have to see how much to add to X ( UK size) to get Y ( US size) and in this case it's +2.5

B: You can use the equation we just formed to get this answer by adding 2.5 to 7.5 which will give you 10
