Question

Write an equation of variation to represent the situation and solve for the indicated information.The number of centimeters y in a linear measurement varies directly with the number ofinches x in the measurement. Pablo's height is 152.4 centimeters or 60 inches. What isMaria's height in centimeters if she is 64 inches tall?

Answer 1

Let x be Maria's height in centimeters

152.4 cm = 60 inches

x = 64 inches

cross-multiply

60x = (152.4)(64)

60x = 9753.6

Divide both-side of the equation by 60

x=162.56 centimeters

Hence,

Maria's height is 162.56 centimeters
