3(2x - 3) = 4x + 1<br> Help
lesantik [10]

Answer:

x=5

Step-by-step explanation:

You first have to distribute. So multiply the 3 with whats inside the parenthesis. So 3 times 2x is 6x. And 3 times -3 is -9. That means that so far you have 6x-9. Now on the other side you have 4x+1. So you move the 9 over to the other side by doing the opposite of it. Meaning +9. So you add 9 to 1 giving you 10. Now you have, 6x=4x+10. Just subtract 4x from 6x, which gives you 2x. Lastly, you divide the 10 by 2x because division is the opposite of multiplication

your realized income is 3167.89/month, and your fixed expenses are 954.32/every 2 weeks. if you save 50% of your discretionary m
svetlana [45]

Answer:

<em>each month, you are saving 629.625</em>

<em />

Step-by-step explanation:

Your income is 3,167.89 each month.

Every 2 weeks, your fixed expenses are 954.32.

=> Average fixed expenses for 1 week is: 954.32 / 2= 477.16

As there are 4 weeks in each month, so that your fixed expenses each month are: 477.16 x 4 = 1,908.64

Your discretionary money for each month = Your monthly income - Your monthly fixed expenses = 3,167.89 - 1,908.64 = 1,259.25

=> Your discretionary money for each month is 1,259.25

As you save 50% of discretionary money each month, so that your monthly saving can be calculated as following:

<em>Monthly saving = Monthly discretionary money x 50% </em>

<em>= 1,259.25 x 50 / 100 = 629.625 </em>

<em />

<em>So that each month, you are saving 629.625</em>
