(Sets Question) In a class of 38 students, 15 play hockey, and twice as many play basketball.
Each student in the class plays either hockey or basketball. Determine the
number of students who play:
a. Both hockey and basketball
b. Only hockey
c. Only basketball

c > -10.55

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
