It takes them 12 seconds to eat the whole sausage.
<h3>What is speed?</h3>
Speed is the rate of change of distance.
Analysis:
If kitten eats x cm, then puppy will eat 14 - x cm
speed = d/t
speed of kitten = 1/2
speed of puppy = 2/3
1/2 = x/t
2/3 = 14 - x / t
t = 2x--------1
2t = 3(14 - x ) -------- 2
substitute t in equation 2
2(2x) = 3(14 - x)
4x = 42 - 3x
7x = 42
x = 42/7 = 6cm
substitute value of x in equation 1
t = 2(60 = 12 seconds.
In conclusion, it takes the both animals 12 seconds to finish the sausage.

Answer:
5/6 , - 5/6
Step-by-step explanation:
square root it
Answer:
Let's solve your system by substitution.
x+y=−5;2x+2y=−5
Step: Solvex+y=−5for x:
x+y=−5
x+y+−y=−5+−y(Add -y to both sides)
x=−y−5
Step: Substitute−y−5forxin2x+2y=−5:
2x+2y=−5
2(−y−5)+2y=−5
−10=−5(Simplify both sides of the equation)
−10+10=−5+10(Add 10 to both sides)
0=5
Step-by-step explanation:
The right answer is A ! :)
