8x+30/10
Simplify the Problem
<em><u>8x+3</u></em>
Let x be the number of mm of pure alcohol to be added:
I will add the mm to express the volume in mm
100mm.(19%) + (100%).x mL = (100 mL+x mL).(40%).
Now right again without the %
100.(0.19) + x.(1) = (100+x).(0.4)
19 + x = = 40 + 04x
x - 0.4x = 40 - 19
0.6 x = 21
x = 21/0.6 and x = 35 mL. This te quantity of pure alcohol should to be added to get a solution at 40%.
Coordinate of Point A = (3,48)
It means, <span>Three ice trays make 48 ice cubes,'cause x-coordinate is number of ice trays and y is number of ice cubes
In short, Your Answer would be Option D
Hope this helps!</span>
