The value of A is RM 205.
Since Billy gave money to a charity over a 20 year period, from Year 1 to Year 20 inclusive, and he gave RM150 in Year 1, RM160 in Year 2, RM170 in year 3, and so on, and Kevin also gave money to the charity over the same 20 years period, but he gave RMA im Year 1 and the amount of money he gave each year increased, forming an arithmetic sequence with common difference RM30, and the total amount of money that Kevin gave over 20 years period was twice the total amount of money that Billy gave, to calculate the value of A the following calculation must be performed:
- Billy = (150 x 20) + 10 + 20 + 30 + 40 + 50 + 60 + 70 + 80 + 90 + 100 + 110 + 120 + 130 + 140 + 150 + 160 + 170 + 180 + 190
- Billy = (150 x 20) + 1900
- Billy = 3000 + 1900
- Billy = 4900
- Kevin = (9800 - (30 + 60 + 90 + 120 + 150 + 180 + 210 + 240 + 270 + 300 + 330 + 360 + 390 + 420 + 450 + 480 + 510 + 540 + 570)) / 20
- Kevin = (9800 - 5700) / 20
- Kevin = 4100/20
- Kevin = 205
Therefore, the value of A is RM 205.

27/6 because this shows that you are dividing 6 from 27.
7. Let x be the money she began with, then
1/3 (x - 4/5 x) = 15
1/3 (1/5 x) = 15
1/15 x = 15
x = 15 * 15 = $225
Therefore, she started with $225
Let x be the number of students surveyed, then
1/2(x - 1/3x - 1/6x) = 9
1/2(1/2x) = 9
1/4x = 9
x = 4 * 9 = 36
Therefore, the number of students surveyed is 36.
The sign will be Positive because there are two negatives
