Answer: x = 17 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
From the question: y α x
⇒ y = kx
y=4 and x = 10 implies
4 = 10k
k = 4/10
k = 2/5
substitute k = 2/5 into the equation
y = 2/5 x
When y = 7 , the equation becomes
7 = [tex]\frac{2x}{5}[/tex]
35 = 2x
35/2 =x
Therefore : 17 [tex]\frac{1}{2}[/tex]
x =
