Complete the table and by inspection of the table, find the solution to the equation 5t = 35.
t | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | - | - | - | - | - |
5t | - | - | - | - | - | - | - | - | - | - | - | - | - | - |
For 5t, the table can be formed as follows:
T | 5t |
3 | 5 × 3 = 15 |
4 | 5 × 4 = 20 |
5 | 5 × 5 = 25 |
6 | 5 × 6 = 30 |
7 | 5 × 7 = 35 |
8 | 5 × 8 = 40 |
9 | 5 × 9 = 45 |
10 | 5 × 10 = 50 |
11 | 5 × 11 = 55 |
From the above solution, we find that:
t = 7 is the solution of the given equation as
5t = 5 × 7
= 35
