Question

Complete the table for the given rule. Rule: y=3x

x y
? 15
10 ?
? 45

Answer 1

x = 5, 15 y = 30

Explanation:

y=3x is the rule, thus you can use it to find all values.

15 = 3x Divide 15 by 3 in order to isolate the variable

5 = x

y = 3(10) Multiply 3 by 10 in order to find y

y = 30

45 = 3x Divide 45 by 3 in order to isolate the variable

15 = x
