-3(x+n) = x what is x

Mathematics
1 answer:
svp [43]3 years ago
8 0

Answer:

x = -3n/4

Step-by-step explanation:

in order to  solve for x in this expression we would open the bracket with -3 according to BODMAS rule. then we would evaluate for the value of x

-3(x+n) = x what is x

-3x-3n= x

-3x = x + 3n

-3x -x = 3n

-4x = 3n

divide both sides by the coefficient of x which is -4

-4x/-4 = 3n/-4

x = -3n/4

therefore the value of x in the expression -3(x+n) = x is evaluated to be

x = -3n/4

Which of the following sequences of numbers are arithmetic sequences?
Pepsi [2]
Answer: B, C, E

-------

The difference between consecutive terms (numbers that come after each other) in arithmetic sequences is the same. That means you add the same number every time to get the next number. To figure out which choices are arithmetic sequences, just see if the differences are the same.

Choice A) 1, -2, 3, -4, 5, ...
-2 - 1 = -3
3 - (-2) = 5
The difference is not constant, so it is not an arithmetic sequence.

Choice B) 12,345, 12,346, 12,347, 12,348, 12,349, ... 
12,346 - 12,345 = 1
12,347 - 12,346 = 1
The difference is constant, so it is an arithmetic sequence.

Choice C) <span>154, 171, 188, 205, 222, ... 
171 - 154 = 17
188 - 171 = 17
The difference is constant, so it is an arithmetic sequence.

Choice D) 
</span><span>1, 8, 16, 24, 32, ...
8 - 1 = 7
16 - 8 = 8
</span>The difference is not constant, so it is not an arithmetic sequence.

Choice E) 
<span>-3, -10, -17, -24, -31, ...
-10 - (-3) = -7
-17 - (-10) = -7
</span>The difference is constant, so it is an arithmetic sequence.

What is the answer to x-1=-5-x
maria [59]

Answer:

x=-2

Step-by-step explanation:

We have the equation x-1=-5-x

In order to solve for x, we need to get all of the x's to one side and everything else to the opposite side

x-1=-5-x

First, we can add 1 to each side

x=-4-x

Now, we can add x to each side

2x=-4

Next, we can divide each side by 2

x=-2

And here is our answer.
