Question

Find the rule to solve for N. X,5,6,n,10 Y,20,24,32,40

Answer 1

Answer:

Step-by-step explanation:

Consider what y values you are getting by letting x = 5 and then letting x = 6.

when x = 5 , y = 20

y = m*5

20 = m*5                      Divide by 5

20/5 = m/5                  

4 = m

when x = 6 y = 24

y = mx

24 = m*6                     Divide by 6

24/6 = m

m = 4

So now we can be sure of our solution for x when y = 32

y = m*n

32 = 4*n                      Divide both sides by 4

32/4 = 4*n/4

n = 8

Answer: n = 8
