<span>Part
1: Jasmine
practices the piano for 30 minutes on Monday. Every day she increases her practice time by 5 minutes. If she continues this
pattern, how many minutes, on the 7th day she will practice Tn = a + (n - 1)d
T7 = 30 + 5(7 - 1) = 30 + 5(6) = 30 + 30
T7 = 60 minutes
Part 2: Anthony
goes to the gym for 10 minutes on Monday. Every day he multiplies his
gym time by 2. If he continues this pattern, on the 5th day she will spend 10(2)^(5 - 1) = 10(2)^4 = 10(16) = 160 minutes in the gym.

The suit case originally weights 48 kg
.75x = 36x = 33/ .75 = 48
Total amount of fencing
= 4x + 3(3x + 1)
= 4x + 9x + 3
= 13x + 3
Answer: 1/15
Pizza cut into fifth, therefore 1 piece = 1/5
1 piece cut into thirds = 1/3 x 1/5 = 1/15
