There are between 24 and 40 students in a class. The ratio of boys to girls is 4:7
How many students are in a class?

Step-by-step explanation:

Let's add the ratios.

The only number that is divisible by 11 and is between 24 and 40 is 33. Let's divide 33 by 11.

Now, let's multiply 3 to each ratio.

Hence, there are 21 girls and 12 boys in the class. The class has a total of 33 students.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
