Simplify 3/2t to 3t/2
16 - 2t = 3t/2 + 9
Multiply both sides by 2
32 - 4t = 3t + 18
Add 4t to both sideds
32 = 3t + 18 + 4t
Simplify 3t + 18 + 4t to 7t + 18
32 = 7t + 18
Subtract 18 from both sides
32 - 18 = 7t
Simplify 32 - 18 to 14
14 = 7t
Divide both sides by 7
14/7 = t
Simplify 14/7 to 2
2 = t
Switch sides
<u>t = 2</u>
You go to a restaurant and your bill is $35.00. Your service was excellent so you leave a 20% tip. What was the total amount paid for the bill including the tip?
10%=$1 for every $10
15%=$1.50 for every $10
20%=2% for every $10
10% of the bill would be $3.50(move the decimal to the tens place)
15% of the bill would be $5.25( halve the 10% and add it to the original 10% tip; $3.50+$1.75)
20% of the bill would be $7.00(double the 10% tip)

Step-by-step explanation:
Use the midpoint formula to find the midpoint of the line segment.
Midpoint formula is a mathematically equation used to measure the halfway point between two data points.
Calculating the midpoint is the same thing as calculating the average of two numbers. Therefore, you can calculate the midpoint between any two numbers by adding them together and dividing by two. For example, suppose you want to find the midpoint between the numbers 2 and 32. First, add the two numbers: 2 + 32 = 34.
I think don't get mad if its wrong :)
Answer:
Step-by-step explanation:
slope of line through (6,-1) and (11,2) = (-1 - 2)/(6 - 11) = 3/5
slope of line through (5,-7) and (8,-2) = (-7 - (-2))/(8 - 5) = -5/3
product of the slopes = -1, so the lines are perpendicular.
Xy+24=x22 that is the answer hope it helps
