Samantha weighs 3/4 as much as her cousin. If Samantha weighs 102 pounds, how much does her cousin weight?

Question

Describe as a linear equation using “x” or “y” as variable names to describe the unknowns.

Answer 1

y = Samantha's weight

 

x = her cousin's weight

 

y = 3x/4

 

102 = 3x/4

 

408 = 3x

 

136 = x

 

her cousin weighs 136
