Answer:
A = 26
Step-by-step explanation:
sum of students = classA + classB + classC
let's say classA = A, classB = B, and classC = C
A + B + C = 66
class A has five more students than class B, so A = 5 more than B so A = 5+B
class C has 2 less students than class B, so C = 2 less than class B = B -2, so C = B-2
A + B + C = 66
A = 5+B
C = B-2
substitute 5+B for A and B-2 for C in the first equation to limit this to one variable (B)
(5+B) + B + (B-2) = 66
3B + 3 = 66
subtract 3 from both sides to isolate the variable and its coefficient
3B = 63
divide both sides by 3 to solve for B
B = 21
A = 5 + B = 5 + 21 = 26
Answer:
The answer is below
Step-by-step explanation:
An independent variable is a variable that does not dependent on other variables. It is the input variable.
A dependent variable is a variable that is dependent on other variables. The dependent variable depends on the independent variable. It is the output variable.
Since porter receives 3 tickets for every dollar, this means the number of ticket is dependent on the money he spend. Therefore the money he spends (d) is the independent variable and the tickets (t) is the dependent variable.
For this case, what we should know is that a polygon is a geometric figure with n sides that is closed. It is usually the union of straight lines.
On the other hand, in order to find the area of a figure, we need it to be closed.
Therefore, the edges of an area are confined by snap points.

FALSE
Answer:
3i √3
Step-by-step explanation:
you can't have the square root of a negative number
so we use "i"
