Answer:
3/14 or 21.428571428571%
Step-by-step explanation:
First you should add all of the animals together.
3 + 4 + 7 = 14
3 out of 14 animals are pigs.
Since x=8/3 is a vertical line,the slope is undefined,
5x - 20 = 8x - 65
-20 = 3x - 65
3x = 45
x = 15
Simplify brackets
2/5(x - 4) = 2x
Simplify 2/5(x - 4) to 2(x - 4)/5
2(x - 4)/5 = 2x
Multiply both sides by 5
2(x - 4) = 10x
Divide both sides by 2
x - 4 = 5x
Subtract x from both sides
-4 = 5x - x
Simplify 5x - x to 4x
-4 = 4x
Divide both sides by 4
-1 = x
Switch sides
<u>x = -1</u>
