Answer:
x mean multiply xd
Step-by-step explanation:
The time it takes for the car to complete one revolution around the track is calculated by dividing the circumference of the circular track by the speed of the car.
This may mathematically be expressed as,
time = circumference / speed
First to find the missing measurement:
17-8 = 9
Perimeter = 57 (add all the sides)
Area = (7 x 8) + (9 x 16) = 200m^2
(it helps to split the shape into two parts)
X-the $5 bills
y-the $10 bills
x+y=20
5x+10y=120
It's a system.
