Calculating the Total Number of Lamps Used for Street Lighting

To calculate the total number of lamps used for street lighting on the two streets, we can use the information provided.

Let's denote: - Number of lamps on the first street as x - Number of lamps on the second street as (1/3)x (since it's three times less)

The total number of lamps used for street lighting on both streets can be calculated by adding the number of lamps on the first street to the number of lamps on the second street.

So, the expression for the total number of lamps used is: x + (1/3)x

Now, let's simplify the expression to find the total number of lamps used.

Simplifying the Expression

To find the total number of lamps used, we can simplify the expression: x + (1/3)x

By combining like terms, we get: 1x + (1/3)x = (4/3)x

So, the total number of lamps used for street lighting on the two streets is (4/3)x.

Conclusion

The total number of lamps used for street lighting on the two streets is (4/3)x.
