The cycle number two is the answer
Answer:
0.62kg
Step-by-step explanation:
Let
x = 40/kg coffee
y = 11/kg coffee
two equations can be derived from the question
x + y = 12 equation 1
40x + 11y = 114 (9.5 x 12) equation 2
multiply equation 1 by 11
11x + 11y = 132 equation 3
subtract eqn 3 from eqn 2
29x = 18
divide both sides of the equation by 29
x = 0.62kg
If f(x) = 4 - 7x then x = -f/7, 0
but if
f(x) = 0 then x = 0.
Maybe The 30% And 70% Is In The Other Triangle And You Do The Same Thing Thats What I Am Guessing Not 100% Sure About It Because I Have Not Learned This Yet! :P
