If you're asking about slope and how to find the equation of the line, you would do it like this:
1) Arrange the equation into slope intercept form (y=mx+b)
2) 6y+2x=12 subtract the 2x from both sides and you get 6y= -2x +12
is in slope intercept form
3) So, m= -2 and b=12
-19 - 7 = 5x - 3x
-26 = 2x
2x= -26
x= -26/2
x= -13
C=180-A-B=180-67-53=60deg.
by sine rule
b/sinB=a/sinA
b=a/sinA*sinB
=13/sin(67)*sin(53)
= 11.28
c/sinC=a/sinA
c=a/sinA*sinC
=13/sin(67)*sin(60)
= 12.23
Set up a proportion to solve.
(4mg/5ml)= (20mg/x ml)
Be sure you line up the mg to mg and the ml to ml.
Notice I have both mg on the numerator and both ml on the denominator.
To solve you need to cross multiply.
4x = 5(20)
4x = 100
divide by 4
x = 25 ml
I hope this helps. :-)
It would just be 20 packages of ten, 4 packages of 50, 2 of 100, 1 100 + 2 50, 1 100+ 1 50 + 5 10, and so on, you just keep adding them up different ways to make 200
