Answer:
1/12
Step-by-step explanation:
Total sub consumed = ¼ + ⅔
= [3(1) + 4(2)]/12 (LCM is 12)
= 11/12
Left = 1 - 11/12 = 1/12

Answer: Choice A
S9 = (9/2)*(2+26)
===============================================
The formula is
Sn = (n/2)*(a1+an)
where
Sn = sum of the first n terms (nth partial sum)
n = number of terms
a1 = first term
an = nth term
In this case,
n = 9
a1 = 2 (plug in n = 1 into the formula an = 3n-1 and simplify)
an = a9 = 26 (plug n = 9 into the formula an = 3n-1 and simplify)
So,
Sn = (n/2)*(a1+an)
S9 = (9/2)*(2+26)
will help us find the sum of the first 9 terms of this arithmetic sequence
Answer:
x = 21/2
Step-by-step explanation:
Step 1: Write equation
-4(3/2x - 12) = -15
Step 2: Solve for <em>x</em>
- Distribute -4: -6x + 48 = -15
- Subtract 48 on both sides: -6x = -63
- Divide both sides by -6: x = 21/2
The distance around an object is called the perimeter. To get the perimeter, you add up the sides. So, 2/18 + 3/12 + 2/12 = your answer.
