Answer:
7x+12 because there is 8x then you subtract 1x which 'll equal 7x and add the 12
Answer:
9240 feet
Step-by-step explanation:
Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile.
Step 1
The total distance Petrov ran in miles is calculated as:
1 lap = 1/4 mile
7 laps = x mile
Cross Multiply
x = 7 × 1/4 mile
x = 1.75 miles
Step 2
What is the total distance Petrov ran in feet?
1 mile = 5280 feet
1.75 miles = x
Cross Multiply
x = 1.75 × 5280 feet
x = 9240 feet
Therefore, the total distance Petrov ran in feet is 9240 feet
Convert 9 yards into feet: 9 yards * (3 feet) / (1 yard) simplifies to 27 feet.
9 yards, or 27 feet, is shorter than 29 feet.
29 feet is longer than 27 feet.
Distance
|a+bi| is the length of the vector from origin to (a,b).
First you need to make a multiplier:
1-(12/100) = 0.78
Then you multiply the price by 1.12 to get the final answer;
22 * 0.78 = 17.16
This means it cost $17.16 after the 12% sales tax.
Hope this helps! :)
