Seperate the questions 12+15=25 ÷ by 3×6= 18-4= the answer
Answer:
y/x = 2.5
Step-by-step explanation:
y ∝ x
change ∝ to = by adding constant k or c
y = kx
Divide both sides by x
y/x = k, also k = y/x
Input the values
k = (7 1/2)/3. Change 7 1/2 to improper fraction to give 15/2
k = (15/2)/3
k =
÷ 3
Change the division sign to multiplication which will change 3 to its inverse(1/3)
k =
× 
k = 
Divide the numerator and denominator by 3 to get 5/2
k = 5/2
From y/x = k,input k into the eqn
y/x = 5/2
y/x = 2.5

18?
-18 divided by [-1/6]
is 18
hopefully that's what you were looking for.?!!
4,6,8 because 4 times 2 is 8 and 6 times 1 equals 6 and 1 times 4 equals 4
