Answer:
--- The equation
The solution is 12 packs i.e. p = 12
Step-by-step explanation:
No options given. So, I will solve generally.
Given
per pack
Required
Determine the equation
This is calculated using:
Divide both sides by 6
Sinx =8/40
in order to solve this you would have to use the inverse which would be Sin^-1(8/40) giving you 11.5
I believe it is -8y + 5x - 3
Use the formula
n(n-1)/2
which is the total number of connections between n points
So,
4(3)/2 = 6
the answer is option C.
Hope this helps
28x + 44y = 964.40
21x + 33y = 723.30
Let's multiply the first equation by 4 and the second by -4
84x + 176y = 3857.6
-84x - 132y = -2893.2
Add the equations together.
0 + 44y = 964.4
Simplify
44y = 964.4
Divide both sides by 44
y = 964.4/44
Since we have the value of y, let's plug 964.4/44 into y for the first equation.
28x + 44(964.4/44) = 964.40
Simplify the left side
28x + 964.4 = 964.4
Subtract 964.4 from both sides
28x = 0
Divide both sides by 0
x = 0
In conclusion,
y = 964.4/44
x = 0
