Hannah wants to buy a $460 camera. She can save $35 each week from her paycheck. However, before Hannah can buy the camera, he must give her brother $65 that she owes him. For how many weeks will Hannah need to save before she can pay back her brother and buy the camera?

15 weeks (roughly 4 months)

Step-by-step explanation:

(460+65)÷35

=525÷35

=15

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

a. -0.3 > -0.33
