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)
Answer:
the answer is the 4/-2
Step-by-step explanation:
you can understand from the answer
Instead of using PEMDAS or the Order of Operations, the student went ahead and solved the equation as though it were written 6 * 12 - 8.
The correct way to solve would be to first solve the parentheses. 12 - 8 is equal to 4. 4 times 6 is 24, giving us an answer of 24.
