No they do not for a proportion
Step-by-step explanation:
Answer:
a:30 b:70 c:80
Step-by-step explanation:
triangle= 180*
3:7:8= 180*
7+3+8= 18
180/18= 10
a= 3x10= 30*
b=7x10= 70*
c=8x10= 80*
Answer: The domain of the function should be whole numbers.
This functions counts the number of cars that pass through an intersection as the domain (or input). Therefore, we would start counting at 0 and go up for each car.
The set of numbers {0, 1, 2, 3, 4, 5, 6, 7 ....} are called the whole numbers.
5x7=35
5x7=5x(5+2)
5x7=(5x3)+(5x4)
5x7=20+15
5x7=35
This is how I would do it :)
