Answer:
-1113
Step-by-step explanation:
You apparently want the sum of the 14-term arithmetic sequence ...
-21, -30, -39, ..., -138
The average term is ...
(-21 -138)/2 = -79.5
so the sum of the 14 terms is ...
(14)(-79.5) = -1113
17
Σ (15 – 9n) = -1113
η = 4
- nth term
aₙ = 15 - 9n
a₄ = 15-9*4 = 15-36= -21
a₁₇ = 15 - 9(17) = -138
- Sum;
S = (a₁ + aₙ)*n/2
n = 14
a₁ = a₄= -21
aₙ = a₁₇ = -138
S = (-21 - 138)*14/2
S = -1113

Answer: 9
Step-by-step explanation: The reason that students get intimidated
by word problems is they try to look at all the information at once.
The best way to approach a word problem
is to break it down sentence by sentence.
In this problem, let's look at the first part of the sentence.
We know that six less than three times a number is 21.
Let's call the number x.
So we know that six less than three times a number means 3x - 6.
A common mistake would be for students to put 6 - 3x.
However, the word "less than" switches the order around.
So we know that six less than three times a number is 21.
So we can write this as 3x - 6 = 21.
Now we have an equation and we can solve for x.
First add 6 to both sides to get 3x = 27.
Now divide both sides by 3 to get x = 9.
So our answer to this word problem is 9.

The Circumference of the circle will be 31.4 feet.
What is circumference of a circle?
Circumference of a circle is the perimeter of a circle.
i.e.
Circumference of a circle = 2πr
We have,
Diameter of circle= 10 feet
So,
Radius of circle feet
Now,
Using the above mentioned formula,
Circumference of a circle = 2πr
i.e.
Circumference of a circle = 2 * 3.14 * 5
So,
Circumference of a circle = 31.4 feet
Hence, we can say that the Circumference of the circle will be 31.4 feet.
