A class voted for for either rollerblading ,swimming,or biking as their favorite summer activity.if rollerblading got 10% percent of the vote and biking got 35%, what percentage of the class voted for swimming?

  The number of balloons varies directly with the number of tables. The two variables are directly proportional. The relationship of balloons to tables is the ratio 5:1, where 5 is the constant of variation. Use the equation y = kx, where k is the constant of variation resulting in the equation y = 5x.

Hope i helped
