Given:
Equations using properties.
To find:
The equation which use the inverse property of multiplication.
Solution:
<u>Inverse property of multiplication:</u>
<em>The product of any number and its reciprocal is always 1.</em>
Let us select the option which uses inverse property of multiplication.
Option A: 
Inverse of
is
. Their product is 1.

This equation uses the inverse property of multiplication.
Option B: 
Inverse of
is 
So, it is not true equation.
Option C: 
Inverse of
is
.
So, it is not true equation.
Option D: ![\left[7 \cdot\left(\frac{5}{7}-\frac{4}{7}\right)\right]+8=9](https://tex.z-dn.net/?f=%5Cleft%5B7%20%5Ccdot%5Cleft%28%5Cfrac%7B5%7D%7B7%7D-%5Cfrac%7B4%7D%7B7%7D%5Cright%29%5Cright%5D%2B8%3D9)
Here also inverse property is not used.
So, it is not true equation.
Hence the equation use the inverse property of multiplication is
.
Answer:−9.6
Step-by-step explanation:
I’d say 1380 definitely not 800 or 580
Try A, $5000. I did 550 divided by 11, which is 50, then multiplied by 10 to find 10%, then multiplied the 10%, which was 500, by 10 to get 100% which is 5,000
A) Let C = Total cost
C = 1.085
b/c) - you need the price of the product you are buying
