The perimeter of a triangular playground is 270 feet. if the ratios of the measures of the sides of the triangle are 5: 6: 7, find the measure of the sides of the playground. 48 feet, 72 feet, 144 feet 60 feet, 80 feet, 100 feet 75 feet, 90 feet, 105 feet 50 feet, 60 feet, 70 feet

Side 1  5x
Side 2 6x
Side 3 7x

           18x
5x+6x+7x = 270 
x=15
Side 1 5x=75 feet
Side 2 6x= 90 feet
Side 3 7x= 105 feet

Thus your answer is 75 feet, 90 feet, 105 feet 

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
