Answer:
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Step-by-step explanation:
This question can be solved using a system of equations:
I am going to say that:
x is the cost of each pack of chicken.
y is the cost of each pack of beef.
2 packs of chicken and 3 packs of beef for $42.50.
This means that
5 packs of chicken and 6 packs of beef for $94.25.
This means that
We have to solve the following system:
I will use the addition method, multiplying the first equation by -2, and adding to the second
-4x + 5x - 6y + 6y = -85 + 94.24
x = 9.24.
And
Each pack of chicken costs $8 and each pack of beef costs $9.24.
Answer:
Step-by-step explanation:
Lines and are parallel because
The distance between two lines and can be calculated using formula
Divide the equation of the second line by 2:
Hence, the distance between two lines is
Answer:
197.9
Step-by-step explanation:
The formula for circumference is 2(pi)r and r is the radius
The diameter is two times the size of the radius, so by dividing the diameter by two, you can get the radius
So, r=63/2
r= 31.5
That means that 2(pi)(31.5) is the circumference
2(pi)(31.5) = 197.9 (rounded to the nearest tenth)
