Final answer:
To find the width of Carter's yard with an area of x square feet and a known length of 10 ft, divide x by 10 to get the width in feet.
Step-by-step explanation:
Carter purchased x square feet of sod for his yard, which has a length of 10 ft. To find the width of his yard, we need to use the formula for the area of a rectangle, which is area = length × width. As we know the area is x square feet and the length is 10 ft, we can rearrange the formula to solve for the width:
A = l × w
x = 10 × w
w = x / 10
Therefore, the width of Carter's yard is x / 10 feet.
