Help me solve the Inequality Word Problem and solve?

1 answer:

julia-pushkina [17]3 years ago

7 0

We can write this as an inequality:
$1 + 3x \ \textless \ x - 5$

We can deal with this very easily:
$1 + 2x \ \textless \ -5$
$2x \ \textless \ -6$
$x \ \textless \ -3$

I solved it for you, I cannot graph due to Brainly not supporting it. Sorry, and hope this helps!

The numbers are 12, 21.

Step-by-step explanation:

x+(x+9)=33

x+x+9=33

2x+9=33

2x=33-9

2x=24

x=24/2

x=12

--------

x+9=12+9=21

What is the sum of the sequence: <br> 1+3+5+7+...1001

Ann [662]

Answer:

The sum of the sequence 1+3+5+7+...1001 is 251001.

Step-by-step explanation:

Given sequence is 1 + 3 + 5 + 7 + ....+ 1001.

Here, $a_0=1,a_1=3,a_2=5$ and so on upto $a_n=1001$

Lets find the difference between each term

$a_1-a_0=3-1=2$

$a_3-a_2=5-3=2$

$a_4-a_3=7-5=2$

We see that the difference between each term of the given sequence is 2 . Thus, it is an Arithmetic sequence.

Since we have to find the sum of the sequence

Sum of sequence of a given Arithmetic sequence is given as :

$S_n=(a_0+a_n)\times \frac{n}{2}$ .............(1)

But, first find the number of terms,

$a_n=a_0+(n-1)d$

Put values, we get,

$\Rightarrow 1001=1+(n-1)2$

$\Rightarrow 1001=1+2n-2$

$\Rightarrow 1001=2n-1$

$\Rightarrow 1001+1=2n$

$\Rightarrow 501=n$

Now put values, $a_n=1001$ , $501=n$ and $a_0=1$

in (1), we get,

$S_n=(a_0+a_n)\times \frac{n}{2}$

$\Rightarrow S_n=(1+1001)\times \frac{501}{2}$

$\Rightarrow S_n=(1002)\times \frac{501}{2}$

$\Rightarrow S_n=251001$

Thus, the sum of the sequence 1+3+5+7+...1001 is 251001.
