Given:
Ratio of cow to chicken is 6:5.
The nunmber of cows is 30.
The objective is to find the number of chickens.
Consider the number of cows and chicken as 6x and 5x.
The value of <em>x</em> can be calculated as,
Now, substitute the value of <em>x</em> to find the number of chicken.
Hence, the number of chicken will be 25.
Answer:
17s−109t
Step-by-step explanation:
Let's simplify step-by-step.
9(3s−3t)−2t−10(8t+s)
Distribute:
=(9)(3s)+(9)(−3t)+−2t+(−10)(8t)+(−10)(s)
=27s+−27t+−2t+−80t+−10s
Combine Like Terms:
=27s+−27t+−2t+−80t+−10s
=(27s+−10s)+(−27t+−2t+−80t)
=17s+−109t
We have that
F(x)=x²<span>-10x+44
</span><span>Group
terms that contain the same variable
</span>f(x)=(x²-10x)+44
<span>Complete
the square Remember to balance the equation
</span>f(x)=(x²-10x+25-25)+44
Rewrite as perfect squares
f(x)=(x-5)²-25+44
f(x)=(x-5)²+19
this is the equation of a vertical parabola with vertex (5,19)
