There are 27 students in a class. There are 5 less girls than boys. Let x = the number of boys and y = the number of girls. How many boys and girls are in the class?

Step-by-step explanation:

x + y = 27

We know that there are 5 less girls that boys, so:

x + (x-5) = 27

x + x - 5 = 27

Solve for x:

2x - 5 = 27

2x = 32

x = 16 boys

y = 11 girls

tell me if you see anything wrong

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
