Answer:
<h2>A. -2y+5x/3x-2y</h2>
Step-by-step explanation:
Given the complex fraction;

First we will find the LCM of the numerator and the denominator as shown below;

Then we divide both equation by multiplying the numerator by the reciprocal of the denominator as shown;

This gives the required answer
Cost of the spa treatment = $42
Percentage of sales tax = 6%
Percentage of tips = 20%
Normally the tips amount is calculated before adding sales tax.
Then
Amount of tips given = (20/100) * 42
= (1/5) * 42
= 8.40 dollars
Amount of sales tax taken = (6/100) * 42
= 252/100
= 2.52 dollars
Then
The total amount spent for spa treatment = (42 + 8.40 + 2.52) dollars
= 52.92 dollars
So we can see that $52.92 has been spent in total for spa treatment and this amount includes a sales tax of $2.52 and a tip of $8.40.
Answer:
3\16
Step-by-step explanation:
movement of snail per hour,1/8×3/2=3/16
Divide by -2 for all of the numbers
64/-32=-2
-32/ 2= -16
-16/2= -8
-8/-2= 4
4/-2= -2
Answer : 4 ,-2
I don't understand what you mean but this might be the answer
