How many gallons of a 65 % sugar solution do we need to mix with
114 gallons of a 40 % sugar solution, so that the resulting mixture is a
46 % sugar solution?

You would need 36 gallons of 65% sugar solution

Step-by-step explanation:

You can always solve these problems with a proportion

The numerator will represent the amount of sugar, the denominator will represent the amount of solution.

First, we have (.4 * 114 = ) 45.6 gallons of sugar.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
