Question

Let n represent an unknown number. If n is double the size of 10, which equation can be used to find n?

10 + 2 = n
10 – 2 = n
10 × 2 = n
10 ÷ 2 = n

Answer 1

n is double size of 10, and that gives us of:

n = 10(2)
n = 20

10 + 2 = 12
10 - 2 = 8
10 x 2 = 20
10 / 2 = 5

If n is 20, the answer is “10 x 2”

Answer 2

10 x 2 =n

Explanation:

If n is double the size of 10 it would be 20. 10 x 2 = 20 which means

n= 20
