Hope this helps!!
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:
y = 3x represents the graph. The point (4, 12) is on the line that is not shown on the graph.
Step-by-step explanation:
The equation of the line that goes through origin= y = mx
Take any to points from the line
(0,0) & ( 2,6)

Equation of the line:
y = 3x
Plugin x = 4,
y = 3*4 = 12
(4,12) is on the line.
