90/2=45
45/3=15
15/3=5
90=2*3*3*5=2¹*3²*5¹
Answer:
8
Step-by-step explanation:
The equation is of the form
y = kx ← k is the constant of proportionality
To find k use the slope formula
k = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (2, 16) ← 2 points on the line
k =
=
= 8
First fill in the blank box is 2 second is 8 third is 80
2 bags, because when you add 5/8 and 1 3/8 you get 1 8/8 which is really 2
