Answer:
m= -13/14
Step-by-step explanation:
use y=mx+b formula!
Answer:
Slope = -3/4
y-intercept = 2
Step-by-step explanation:
Make 2 equations from the question first
x is the number of pints for type 1
y is the number of pints for type 2
The equation
x + y = 120
60% x + 85% y = 65% (x + y)
Solve the equation
From the 2nd equation
0.6x + 0.85y = 0.65(x + y)
0.6x + 0.85y = 0.65x + 0.65y
0.85y - 0.65y = 0.65x - 0.6x
0.2y = 0.05x
y = 4x
From the 1st equation
x + y = 120
x + 4x = 120
5x = 120
x = 24
y = 4x
y = 96
The first type should be 24 pints, the second type should be 96 pints
Since there could be no more than 12 the multiples of 1/3 untill a denominator of 12 are 2/6 3/9 and 4/12
I think it would be 7.5!!
