Divide (12n^3+8n^2-6n)/2n^2

nexus9112 [7]

$\frac{12n^{3} + 8n^{2} - 6n}{2n^{2}} = \frac{12n^{3}}{2n^{2}} + \frac{8n^{2}}{2n^{2}} - \frac{6n}{2n^{2}} = 6n + 4 - \frac{3}{n}$

-1 3/5 divided by (-2/3) write as mixed number

hichkok12 [17]

Step-by-step explanation:

$- 1 \frac{3}{5} \div \frac{ - 2}{3}$

Convert the mixed numbers above to improper fractions. Thus:

$\frac{ - 8}{5} \div \frac{ - 2}{3}$

In order to simplify the fractions above, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that -2/3 to -3/2. Hence,

$\frac{ - 8}{5} \times \frac{ - 3}{2}$

$\frac{ - 8 \times - 3}{5 \times 2}$

$= \frac{24}{10}$

$= 2 \frac{4}{10}$

$= 2 \frac{2}{5}$

Mike earns $6.50 per hour plus 4% of his sales enter an equation for mikes total earnings, e, when he works x hours and has a to

Cerrena [4.2K]

First identify what each variable means. since X is the amount of hours he works, and he makes $6.50 an hour, you know you need to multiply those two numbers together creating the 6.50x. You also know Y is his total sales, and he earns 4% of Y. To find 4% of Y you need to turn the percent into a decimal, and to do this you move the decimal two spaces to the left. Since 4 is a whole number, the decimal is after the 4 so you get .04 as your decimal. Then youd multiply .04 by Y getting .04y. Lastly you add 6.50x + .04y to get E, mikes total earnings. So your final equation is

6.50x + .04y = e

Hope this all makes sense
