Question

Ann thought of a number N, multiplied it by 5 and added 7. Then she told the result R to Jim. Write a formula that will tell you the value of R for any value of N

Answer 1

`R=5N +7`

Explanation:

We want to write a formula for the statement:

Ann thought of a number N, multiplied it by 5 and added 7.

When we multiply N by 5, we get 5N

When we add 7 to 5N we get 5N+7

Our formula now becomes:

R=5N +7
