<h2>Answer:</h2>

The compound inequality that represents this situation is:'

                      20 ≤ s ≤ 50

<h2>Step-by-step explanation:</h2>

We are given information that:

On a road in the city of Rochester, the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.

This means that the speed has to be greater than or equal to 20 but it can't exceed 50 i.e. it has to be less than or equal to 50.

Let s denote the speed.

This means that the compound inequality that can be formed using this information is:

                  20 ≤ s ≤ 50

Let s represent speed.

20 \le s \le 50

To graph it, draw a number line. Show zero, 20, 50 and arrowheads at both ends. Draw closed circles at 20 and 50 and shade in between.

Answer:

The number of men was 80

The number of women was 70

Step-by-step explanation:

The question in English is

Having organized a bingo has raised $1900. For the entrance of men $15 and women $10 and an attendance of 150 people has been reported. Determine the number of men and the number of women who participated in the bingo.

Let

x----> the number of men

y----> the number of women

we know that

x+y=150

x=150-y -----> equation A

15x+10y=1,900 -----> equation B

substitute equation A in equation B and solve for y

15(150-y)+10y=1,900

2,250-15y+10y=1,900

15y-10y=2,250-1,900

5y=350

y=70

Find the value of x

x=150-70=80

therefore

The number of men was 80

The number of women was 70
