Answer:
480
Step-by-step explanation:
Sn = n÷2 × (2a + (n-1)d)
n = 20 a = -14 d = 4
S20 = 10 × (-28 + 19 × 4) = 480

Hahahaha ewan ko hindi ko alam yan eh sana alam mo (29) hahah
3/4 is greater because it's decimal is bigger then 11/16's decimal
Answer:
Step-by-step explanation:
<u>3n+2 is divisible by p:</u>
<u>8n+3 is divisible by p:</u>
<u>Solve each equation for n:</u>
- n = (px - 2)/3
- n = (py - 3)/8
<u>Eliminate n and solve for p:</u>
- (px - 2)/3 = (py - 3)/8
- 8(px - 2) = 3(py - 3)
- 8px - 16 = 3py - 9
- 8px - 3py = 7
- p = 7/(8x - 3y)
As we see p could get 1 or 7 as natural number. Since 1 is excluded, the only solution is 7, and 8x - 3y must equal to 1.
Answer:
-3/2/5
Step-by-step explanation:
8p + 2 > -15 - 2
5p > -17
P > - 17/5
P > - 3/2/5
