Solution
Part A
The general form of the n-th term = a + (n-1)d
Here we are given the 8th term A8 = 28
, common difference (d) = 6
A8 = a + (n - 1) 6
28 = a + (8- 1)6
28 = a + 7*6
28 = a + 42
a = 28 - 42
a = -14
Part B
n-th term is 760. a = -14 and d = 6.
Plugging in the values in the general form, we get
760 = -14 + (n -1)6
760 = -14 + 6n - 6
760 = -20 + 6n
6n = 760 + 20
6n = 780
Dividing both sides by 6, we get
n = 780/6 = 130
The value of n is 130
Answer:
Step-by-step explanation:
3x+4 = 5x-16
-2x+20 = 0
-2x = -20
x = 10
3*10+4 = 5*10-10 = 34
34*2 = 68
JL = 68
The answer is C because it is showing the total for both
Answer:
3311 mililiters
Step-by-step explanation:
1 L = 1 liter = 1000 mililiters
3.311L = 3.311 liters = 3.311*1000 = 3311 mililiters
