Answer:6
Step-by-step explanation:
A.
You can either use long division or just plug it in and see which one works. It has to end with 11 because last number is 88. So either A or C then test those 2
Lets get this into y-intercept form first, which is y =mx+b:
8(4+x)-3 = 12(x+y)+5
32+8x-3 = 12x+12y+5
-4x+24 = 12y
-1/3x+2 = y or y= -1/3x + 2
X intercept:
0 = -1/3x + 2
-2= -1/3x
6 = x
X intercept is (6,0)
Y intercept:
y = -1/3(0) + 2
y= 2
Y intercept is (0,2)
notice above... we use the decimal format for the percentage, thus 20% is really just 20/100, 40% is 40/100 and so on.
so.. whatever "x" and "y" amounts are, we know they have to add up to 60 Liters, that is x+y = 60
and whatever the concentration amount of each is, it must add up to (60)(0.40), that is 0.20x+0.50y=(60)(0.40)
thus
solve for "x", to see how much of the 20% solution will be needed
what about "y"? well, y = 60 - x
