Answer:

There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.

Describe a real- world situation that can be modeled by the equation 15x = 135. Solve the equation and explain what the solution
dedylja [7]
A situation could be for example if you wanted to buy a large amount of {something} and you had $135. To find out how many you would be able to buy, you would solve the equation.

15x = 135 \\ \frac{15x}{15} = \frac{135}{15} \\ x = 9

So 9 would be the amount of {something} that you could buy.
