Answer:
12x12=144 doughnuts
Step-by-step explanation:
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:
x = -3
Step-by-step explanation:
-8x - 18 + 7 + 2x = 5 - 3x - 4 + x
-8x + 2x + 3x - x = 18 - 7 + 5 -4
-4x = 12
x = -3
n/5
If this is incorrect, then i am sorry.
