Answer:
Step-by-step explanation:
Set up an equation, where x is the number of gallons of 60% antifreeze solution.
Represent the percentages of antifreeze with decimal values.
0.6x + 0.3(80) = 0.5(x + 80)
Simplify and solve for x:
0.6x + 24 = 0.5x + 40
0.1x = 16
x = 160
So, you have to mix 160 gallons of a 60% antifreeze solution
It means that the equations answers are
odd (numbers 1,3,5 ,7,9)
even numbers (2,4,6,8,10)
or neither (0 or infinity)
2x; 10-2=8(rise) 6-2=4(run) 8/4=2
