Question

Find the rule. solve for n

x y
3. 30
4. 40
6. n
7. 70

Answer 1

3. 30

4. 40

5. ?

6. n

7. 70

I think 5 is missing, so it is 50

then n=60

n is 60 and the rule is 10y

Explanation:

x=10

this is because multiply x by y

y is your number (for the first one, y=3, second y=4, etc.)

x*y or 10y.

Just substitute y for a number and you'll find the answer.

You need to find 6 so replace y with 6

10*6=60.
