The answer is 1/x.

First, multiply the powers together.
-3• 1/3
-3/3
-1

So place that over your base of x, you get, x^-1.

Simplify this further by following the negative exponent rule, move the expression to the denominator.

Your answer is positive and in simplest form.
1/x

Each pants leg on page 8 has an opening with a circumference of 8.5 inches. It took 15 stitches to make 3 inches in width. How m

lord [1]

Answer:

43 stitches.

Step-by-step explanation:

We have been given that each pant's leg has an opening with a circumference of 8.5 inches. It took 15 stitches to make 3 inches in width. We are asked to find the number of stitches required to make up the circumference.

Let us find stitches needed to make 1 inch by dividing 15 by 3.

$\text{Stitches needed to make 1 inch}=\frac{15}{3}$

$\text{Stitches needed to make 1 inch}=5$

Since 5 stitches make 1 inch, so to find stitches needed to make 8.5 inches, we will multiply 8.5 by 5 as:

$\text{Stitches needed to make 8.5 inches}=5\times 8.5$

$\text{Stitches needed to make 8.5 inches}=42.5$

Upon rounding to nearest stitch, we will get:

$\text{Stitches needed to make 8.5 inches}\approx 43$

Therefore, 43 stitches will make up the circumference.
