Two classrooms have a total of 45 people in them. the first class is a math class with 5 more students that the science class. how many are in each class?

20 students in science class, 25 in math

Step-by-step explanation:

so let 1 classroom= x

so the other classroom= x+5

if there is a total of 45 students

x+x+5=45

2x=45-5

2x=40

x=20

12cm

the answer is d

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
