Answer:
x = 9
Step-by-step explanation:
x/3 = 6/2
~Simplify
x/3 = 3
~Rewrite
1/3x = 3
~Multiply 3 to both sides
x = 9
Best of Luck!
So weight=x
blood=y
we got that when
y=kx
when y=4.6, then x=160
4.6=160k
divide both sides by 160
0.02875=k
the direct variation is
y=0.02875x
so plug in x and get y
the answers in (x,y) form is
(0,0)
(50,1.4375)
(75,2.15625)
(100,2.875)
(125,3.59375)
(150,4.3125)
