2 <em>x</em> ⁻¹ <em>y</em> / (<em>x</em> ³ <em>z</em>) = 2 <em>y</em> / (<em>x</em> ⁴ <em>z</em>)
… = 2 × 8 / (2⁴ × (-1))
… = 16 / (-16)
… = -1
I think it’s D) 9 because when you find the mean of a set of values you are taking into account and adding all of the numbers, and then dividing them by how many numbers there is, so the mean would be summarizing all of them, hope this helps
195 divided by 20 = $9.75
Mark brainliest please and thank you :)
Step-by-step explanation:
8.3 = 8+ 0.3
= 8 + 3/10
= 8 3/10
Let

be the length of the rectangle and

be the width. In the problem it is given that

. It is also given that the area

. Substituting in the length in terms of width, we have

. Using the zero product property,

. Solving these we get the width

. However, it doesn't make sense for the width to be negative, so the width must be

. From that we can tell the length

.
