When two times a number is decreased by 3 the result is 11 what is the number

2x - 3 = 11

Solve:

2x = 14

x = 7

The answer is 7

Hi there!

Let's replace "a number" by "x":

- two times x = 2x

- decreased by 3 = -3

Here's what the equation should look like:

2x - 3 = 11

Now that you have written down your equation, all you have to do now is solve it for "x" by isolating it :

2x - 3 = 11

Add 3 on each side of the equation

2x = 14

Divide each side of the equation by 2

x = 7

Your answer is: The number is 7.

There you go! I really hope this helped, if there's anything just let me know! :)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
