Algebraic equations include "variable" which are unknowns that you have to solve the equation to find out their value
You're just a step away from the equation of the line that's perpendicular to [ y = 5/6 x + 7 ]. ... You know that its slope is -6/5 and that it contains the point (3, 2). ... Find the equation of that line. Then find the point where the two lines intersect. Then find the distance between that point and (3, 2). SIR !
The answer is 2. Because every 2 cups pf flour is 1 half a sugar and, they are asking for 8 so thats 4 half cups of sugar, and if you mix another half with another half it would be 2 cups of sugar
