You would add common like numbers which will give you 8n - 4 = 0 then solve it which will give you 8n = 4 now divide 

your answer would be 

N= 4/8 and if you simplifyit it will be N= 1/2

Hope this helped

Which equation represents the line that passes through the point (1,5) And has a slope of -2?
posledela

The correct answer would be A.

We can immediately eliminate C and D because they have the slope listed as 2 rather than -2.

Because we're looking for the line that passes through (1, 5), we know that the y-intercept has to be 7, because from (0, 7) we get to (1, 5) when we apply the slope of -2.

Thus, the answer is A.

Which of the following options have the same value as 5\%5%5, percent of 353535?
professor190 [17]

Answer:

\frac{5}{100}\times35

0.05\times35

Step-by-step explanation:

<u><em>Given:</em></u>

Which of the following options have the same value as 5% 35, percent of 35?

<u><em>Following Options:</em></u>

5 \times 35

\frac{5}{100}\times35

0.5\times0.35

0.05\times35

\frac{5}{10}\times35

<u><em>Solve:</em></u>

5 % = 0.05=\frac{5}{100}

Thus the following options:

5 \times 35           [ False x ]

5 does not equal 5%

\frac{5}{100}\times35         [True √ ]

5% =\frac{5}{100}

0.5\times0.35      [ False x ]

0.5 = 0.50

0.05\times35       [True √ ]

5% = 0.05=\frac{5}{100}

\frac{5}{10}\times35          [ False x ]

\frac{5}{10}=0.50

Therefore, the options [B] \frac{5}{100}\times35 and [D] 0.05\times35 is True.

Which expression is equivalent to 4(x+2)
Alekssandra [29.7K]

Answer:

4x+8

Step-by-step explanation:

We have been given an expression 4(x+2). We are asked to find equivalent expression to our given expression.

Using distributive property a(b+c)=ab+ac, we will get:

4\cdot x+4\cdot2

4x+8

Therefore, the expression 4x+8 is equivalent to our given expression.
