Just did this one.


The perimeter is the sum of the sides.

n + (3n - 4) + (3n - 5) = 33

7n - 9 = 33

7n = 42

n = 6

3n-4=18-4=14

3n-5=13

Check: 6+14+13=33, good

Answer: 6 cm, 14 cm, 13 cm

Arturiano [62]

Answer:

<u>There are 18 girls in a group that has 16 boys.</u>

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Number of girls in the grade = 81

Number of the boys in the grade = 72

Number of students in the grade = 81 + 72 = 153

2. Let's find the number of girls in a group that has 16 boys.

For getting that number we will use the Rule of three simple, this way:

Number of girls in a group that has 16 boys = (81 * 16)/72

Number of girls in a group that has 16 boys = 1,296 / 72

<u>Number of girls in a group that has 16 boys = 18</u>

<u>There are 18 girls in a group that has 16 boys.</u>
