The total cost of 4 goldfish and 3 guppies is $29. 3 goldfish and 5 guppoes cost $30. How much does each cost
Aneli [31]

let the goldfish be x and the guppies be y

4x + 3y = 29...equ(1)

3x + 5y = 30...equ(2)

multiplying equation 1 by 5 and equation 2 by 3

20x + 15y = 145...equ(1)

9x + 15y = 90...equ(2)

subtracting equation 2 from 1

11x = 55

∴x = 5

 substituting the value of x into equation

4(5) + 3y = 29

20 + 3y = 29

3y = 9

∴y =3

Given an=n^3-2n what is a3<br><br> please don't attach file!!!!
sineoko [7]

Answer:

21

Step-by-step explanation:

Try using this notation:  a(n)     and not    an.

an=n^3-2n becomes    a(n) = n^3 - 2n.

Then a(1) = 1^3 - 2(1) = 1 - 2 = -1

         a(2) = 2^3 - 2(2) = 8 - 4 = 4

         a(3) = 3^3 - 2(3) = 27 - 6 = 21
