3(x-4) = 2(-2x + 1)this is confusing me​

Mathematics

5 0

Answer:

x = 2

Step-by-step explanation:

<em>Distribute</em>

3 (−4) = 2 (−2+1)

3 − 12 = 2 (-2x +1)

<em>Distrubute again</em>

3x - 12 = -4x + 2

<em>Add twelve to both sides of the equation</em>

<em>Simpfly</em>

3x = -4x + 14

<em>Add 4x to both sides of the equation</em>

<em>simpfly</em>

7x = 14

<em>Divide both sides of the equation by the same term</em>

<em>Simpfly</em>

x = 2

Complete the table by writing the fraction as a decimal and as a percent
aniked [119]

Answer:

Decimal = 0.6

Percentage = 60%

Step-by-step explanation:

Let's simplify the fraction.

\frac{120}{200}  =  \frac{60}{100}  = 0.6

Hence the Decimal is 0.6

To express 120/200 in percentage , we have to multiply the fraction with 100.

\frac{120}{200}  \times 100 =  \frac{120}{2}  = 60\%

Hence the percentage value is 60%

Consider the sequence: 8, 11, 14, 17, 20, 23, 26, ... Write a recursive definition.
Amiraneli [1.4K]

The first term is 8, so a_{1} = 8

Each time we want a new term, we add on 3

8+3 = 11

11+3 = 14

14+3 = 17

17+3 = 20

23+3 = 26

and so on

This recursive step of adding on 3 to the prior term is written as this: a_{n} = 3 + a_{n-1} which says "to get the nth term, add 3 to the term just before the nth term"

Based on what you posted for your answer choices, the final answer is likely choice C. However it seems some weird typo happened.

2/3x=−1/3x−4<br><br> (they are not being divided)
Mashutka [201]
2/3(x)-(-1/3(x)-4)=?
?=0

1÷3 = 0.3

2/3(x) - 0 -1/3(x) = ?
? = 0

2 ÷ 3 =.67

4(3)/ 3

your "x" becomes a negative

So, (-x) - 12 / 3 - 2/3(x)
we get the "12" from multiplying 4(3) from each other

Your like term of this problem▶ -x + 12

2(x) - (-x) - 12 / 3

3(x) + 12

x + 4 = 0
-4 -4
---- ----
4x - 4

4x - 4 = 0

We have one solution to this equation

So, therefore your answer for this question is:
x = -4
