Solve equation <br> -8n+7(8+3n)=-16+4n
spin [16.1K]

Answer:

<h2><u><em>-8</em></u></h2>

Step-by-step explanation:

Solve equation

-8n + 7 * (8 + 3n)= -16 + 4n

-8n + 56 + 21n = -16 + 4n

13n + 56 = -16 - 56

13n -4n = -16 - 56

9n = -72

n = -72 : 9

<u><em>n = -8</em></u>

In the stock market an amazon stock share rose 4 and 1/2 points on Wednesday rose 3 and 3/8 points on Thursday and fell 2 and 1/
Vika [28.1K]

Answer:

In the three days the Amazon stock share rose by  5\frac{5}{8}

Step-by-step explanation:

Given:

Amazon stock share

rose 4 and 1/2 points on Wednesday

rose 3 and 3/8 points on Thursday

fell 2 and 1/4 points on Friday

To find the overall change.

Solution:

<em>The change in share on Wednesday is given as = +4\frac{1}{2}</em>

<em>The change in share on Thursday is given as = +3\frac{3}{8}</em>

<em>The change in share on Friday is given as = -2\frac{1}{4}</em>

Thus, the over all change is given by:

4\frac{1}{2}+3\frac{3}{8}-2\frac{1}{4}

<em>In order to combine mixed numbers, we will work the whole numbers and the fractions separately.</em>

⇒ (4+3-2)+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})

⇒ 5+(\frac{1}{2}+\frac{3}{8}-\frac{1}{4})

To combine fractions, we will take least common denominator.

<em>The L.C.D. 2,4 and 8 = 8  as it is the least common multiple for all the denominators</em>

So, we multiply the numerators with the corresponding numbers to make the denominators common.

⇒ 5+(\frac{1\times 4}{2\times 4}+\frac{3}{8}-\frac{1\times 2}{4\times 2})

⇒ 5+(\frac{4}{8}+\frac{3}{8}-\frac{2}{8})

Combining the numerators.

⇒ 5+\frac{4+3-2}{8}

⇒  5+\frac{5}{8}

⇒  5\frac{5}{8}

The overall change for the three days can be given as :  +5\frac{5}{8}

This means the share rose by  5\frac{5}{8}
