Question

Y varies directly with x it has a constant rate of change of 6. When the value of y is 11, then the value of x could be?

Answer 1

Answer: $\frac{11}{6}$

Explanation:

y varies directly with x means: $\frac{y}{x} = k$  ; where k is the rate

• $\frac{y}{x} = k$
• $\frac{11}{x} = 6$
• $(x)\frac{11}{x} = 6(x)$
• 11 = 6x
• $\frac{11}{6} =\frac{6x}{6}$
• $\frac{11}{6} = x$
