Answer: f = 2/5 (0.4)

Step-by-step explanation:

1. Re-order terms so constants are on the left

f x 5 = 2 OR f(5)=2

2. Divide both sides by the same factor

f(5)=2 --> 5f/5 = 2/5

Add. 56+234 Enter the sum in the box as a mixed number in the simplest form.

Kobotan [32]

Answer:

290

Step-by-step explanation:

First, add two digit number from them.

50 + 30 = 80

Second, add the last two numbers.

6 + 4 = 10

So, add these two results.

80 + 10 = 90

Final, all of theses results are added to three digit number of second number.

So, final result is

200 + 90 = 290

What is the sum of the first 37 terms of the arithmetic sequence?

lidiya [134]

Answer:

The sum of the first 37 terms of the arithmetic sequence is 2997.

Step-by-step explanation:

Arithmetic sequence concepts:

The general rule of an arithmetic sequence is the following:

$a_{n+1} = a_{n} + d$

In which d is the common diference between each term.

We can expand the general equation to find the nth term from the first, by the following equation:

$a_{n} = a_{1} + (n-1)*d$

The sum of the first n terms of an arithmetic sequence is given by:

$S_{n} = \frac{n(a_{1} + a_{n})}{2}$

In this question:

$a_{1} = -27, d = -21 - (-27) = -15 - (-21) = ... = 6$

We want the sum of the first 37 terms, so we have to find $a_{37}$

$a_{n} = a_{1} + (n-1)*d$

$a_{37} = a_{1} + (36)*d$

$a_{37} = -27 + 36*6$

$a_{37} = 189$

Then

$S_{37} = \frac{37(-27 + 189)}{2} = 2997$

The sum of the first 37 terms of the arithmetic sequence is 2997.
