3/4 the lower denominator is always the greatest.. Remember That!;)
The first equation, 2x+y-8=0 :)
1. 45/6 = 7.5
7.5*10 = 75
So the penguin walks 75 ft in 45 seconds.
2. 45/10 = 4.5
4.5*6 = 27
The penguin takes 27 seconds to walk 45 ft.
The answer can be found by found ride over run so 4/2 or 2/1=2
Mean is when u add all the numbers up and then divide how many numbers there are e.g 22 + 1 + 3=
22+1+3=26 divide by 3=8.666666666666667
