Hello there! With the values of "x" and "y", they fill in the parenthesis. -3 + 5 is 2, because adding into a negative makes the number go up, or just simply subtracting 3 from 5 works as well. However, there is a 0 beside it, so we raise 2 to the 0 power. Anything that is raised to the 0 power is always equal to 1. And there is no other part of the question, so 1 is our answer. The answer is C: 1.

There are a total of 66 students in the
attashe74 [19]

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

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods
