When comparing the values of two numbers, you can use a number line to determine which number is greater. The number on the right is always greater than the number on the left. In the example below, you can see that 14 is greater than 8 because 14 is to the right of 8 on the number line.

Question:

A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?​

Answer:

200 + 25x < 750

Number of seats in a row must be less than 22

Step-by-step explanation:

Given

Total = Less than 750

Current Seats = 200

Rows = 25

Seat per row = x

Required

Represent as an inequality

The scenario will be represented as:

Current\ Seats + Rows * x = Total

Substitute 200 for Current Seats

200 + Rows * x = Total

Substitute 25 for Rows

200 + 25* x = Total

200 + 25x = Total

Substitute <750 for Total.

The equation then becomes

200 + 25x < 750

Solving further:

25x < 750 - 200

25x < 550

x < \frac{550}{25}

x < 22

This means that:

Number of seats in a row must be less than 22

Answer:

We have 9 = 3^2;

Then, 9^x = (3^2)^x = 3^(2x);

We solve  3^(2x) = 3^40;

2x = 40;

x = 20 ÷ 2;

x = 10;
