Considering that the hallway is rectangular in shape such that its perimeter is calculated by the equation,
P = 2L + 2W
where P is perimeter, L is length, and W is width. Substituting the known values,
10.4 = 2L + 2W
Dividing both sides of the equation by 2,
5.2 = L + W
W = 5.2 - L
A. Coefficient
The number before a variable is called a coefficient. The sum is the addition of two numbers, the variable is the letter or the unknown number, and the term would be the coefficient and the variable together, so “2x” would be the term. I believe that’s right.

Answer:
there are 18 girls
Step-by-step explanation:
for every 2 boys there are 3 girls
so then you can say 2/5 of the class are boys and 3/5 are girls
and you have to calculate 3/5 of 30 so you have to divide 5 and then multiply by 3 so 30 divided by 5 is 6 the n multiply 6 by 3 and the answer is 18.
Hope this helps
