2. Suppose y varies directly with x, and y = 25 when x = 140. What is the value of x when y = 36? (1 point) * 140 * 165 * 201.6 * 176

OpenStudy (blurbendy):

y = kx substitute y and x accordingly to find k then use k and y to find what x is when y = 36

not sure i get you

OpenStudy (blurbendy):

y varies directly with x, can be represented as the equation: y = kx in the first part, if y = 25, and x = 140, then we can solve for k Solve for k, then use what you get for k to solve for x in 36 = kx
