Solve the algebraic system using elimination

 

2x + 6y = 8

4x + 3y = 13

 

A) x = 3

B) y = 2

C) ( 3 , 1/3 )

D) 6x + 9y = 21

E) None of the above

 

 

Solution for last week : A, 1840 cubic inches of space left

Volume = box – ball

Volume = a3 – 4/3πr3

V = 143 – 4/3π63

V = 2744 – 4/3(3.14)(216)

V = 2744 – 904.32

V = 1839.68

V = 1840 cubic inches
