Answer:
136
Step-by-step explanation:
Take 68 x 2 since the side lengths are equal.
Your body eliminates about .015 of BAC per hour.
Let the number of goats be 'x'.
Therefore, the number of chicken will be 50-x
Total number of legs the goats will have= 4x (goats have 4 legs)
Total number of legs chickens will have= 2(50-x) (chickens have two legs).
4x + 2(50-x)=140
4x+100-2x=140
2x+100=140
2x=40
x=20.
There are 20 goats and 30 chickens.
Answer:
a) 10/3
Step-by-step explanation:
2x - 6 + 5x = 1/3 x - 9 + 2y
7x - 6 = 1/3 x - 9 + 2y
or
2y = 7x - 1/3 x - 6 + 9
2y = 21/3 x - 1/3 x + 3
2y = 20/3 x + 3
y = 20/6 x + 3/2
y = 10/3 x + 3/2
Y = mx + b where m = slope
In this case slope m = 10/3
