Answer:
You will be paying $41.30 in total.
Step-by-step explanation:
The cost of the meal is $35 and you want to leave 18% tip on the meal.
We want to find the total amount that will be paid.
First, we have to find 18% of $35 and then, add it to the original bill ($35).
18% of 35 is:
18/100 * 35 = $6.30
The tip is $6.30, therefore, the total amount paid will be:
$35 + $6.30 = $41.30
You will be paying $41.30 in total.
Step-by-step explanation: Your answer is in the photo
1. Take an arbitrary point that lies on the first line y=3x+10. Let x=0, then y=10 and point has coordinates (0,10).
2. Use formula
to find the distance from point
to the line Ax+By+C=0.
The second line has equation y=3x-20, that is 3x-y-20=0. By the previous formula the distance from the point (0,10) to the line 3x-y-20=0 is:
.
3. Since lines y=3x+10 and y=3x-20 are parallel, then the distance between these lines are the same as the distance from an arbitrary point from the first line to the second line.
