A banner has a length of 10 feet and an area of 7 square feet. What is the width of the banner?

the width is 0.7 feet

Step-by-step explanation:

Well we know that area = length * width. We know both the area and length, but not the width. Let's substitute the area and length in this equation, and substitute x for the width.

7 = 10 * x, or 7 = 10x

Now, solve for the width, or x, by dividing both sides by 10.

7 (/10) = 10x (/10)

7/10 = x

Simplify 7/10 = 0.7

So the width of the banner is is 0.7 ft!
