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
6/35
5 5/6 = 35/6, the inverse would be 6/35
3x + 3y = 0
7x - y = 8
the answer is 92.
do 28 times 4, 28 for the days and 4 for the total laps each day.
