5n + 3 + 4n = 30 combine the like terms on the left
9n + 3 = 30 Subtract 3 from both sides
9n = 30 - 3
9n = 27 Divide by 9
n = 27/9
n = 3
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
Order the fractions in ascending order:
{1/6,1/8,1/3}
={4/24,3/24,8/24}
=> in ascending order:
3/24,4/24,8/24
= 1/8, 1/6, 1/3
1/27
Cuz y=3^(-3)=1/(3^3)=1/27
