Answer:

6x-5

Step-by-step explanation:

We apply distributive property to get rid of the first parenthesis, by multiplying each term inside by the factor 1/6:

\frac{1}{6} (30x+24)-\frac{1}{7} (63-7x)\\\frac{30}{6} x+\frac{24}{6} -\frac{1}{7} (63-7x)\\5x+4-\frac{1}{7} (63-7x)

now we get rid of the second parenthesis by multiplying the factor "-\frac{1}{7}" times each of the terms inside the parenthesis (notice here that this factor is negative , so it will flip the signs of the terms it multiplies):

5x+4-\frac{1}{7} (63-7x)\\5x+4-\frac{63}{7} +\frac{7}{7} x\\5x+4-9+x

Next we combine like terms:

5x+4-9+x\\5x+x+4-9\\6x-5

Simplify the following complex fraction.(3/7---1/3)2/3-----1/7
Yakvenalex [24]
Please retype this fraction.  If by "---" you mean "subtraction," type 3/7-1/3.

Let's assume that the problem is as follows:  (3/7-1/3)(2/3)-1/7;
first, find the LCD of 3/7 and 1/3 and then combine 3/7 and -1/3).
second, multiply your result by (2/3).
third, subtract 1/7 from your result.

If, however, your "---" and "-----" mean "division, then the above is all wrong.

If that's the case, then please retype your whole question.

You could express "the quotient of 2/3 and 1/6" as follows:
   
            2
          ----
            3

------------------------
            1
          -----
             6

Is that what you meant?

Sorry to be picky, but it's very important that you express math properly.

alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip. which expression represents the total amount that alexi
Alexeev081 [22]
He is leaving 20% tip of the bill of $58

20% extra

So total amount = 100% + 20% = 120%

120% of 58

(120/100) * 58

1.2 * 58

= 69.6

So total amount Alexi needs to pay = $69.60
