Answer:

\frac{(x - 4)}{(2x + 1)} - 3 = \frac{-7x- 7}{3x + 1}

Step-by-step explanation:

Given

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

Required

Solve

Express 3 as a fraction

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

Take LCM

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

\frac{x - 4 - 6x - 3}{3x + 1}

Collect Like Terms

\frac{x - 6x- 4  - 3}{3x + 1}

Simplify like terms

\frac{-7x- 7}{3x + 1}

Hence:

\frac{(x - 4)}{(2x + 1)} - 3 = \frac{-7x- 7}{3x + 1}

Answers:

A.   6 Large taxis = 42 seats 9 Small taxis = 36 seats = 78  seats in total

  B.  6 Large taxis =  $498 + 9 Small taxis = $450     498+450= $948

   

    C.  5 Large taxis and 10 Small taxis

Step-by-step explanation:

A.   6 Large taxis = 42 seats 9 Small taxis = 36 seats = 78  seats in total

If I did 8 small taxis the total number of seats would be 74, so I did one small taxi more to make it fair. There would be seats for everyone but 3 seats extra

  B.  6 Large taxis =  $498 + 9 Small taxis = $450     498+450=948

   

    C.  5 Large taxis and 10 Small taxis

While the more small taxis there are, the more cheaper it is for Max but the less seats there would be for 75 people, So I did 1 more small taxi and 1 less large taxi.

The total number of seats now is 75 seats which is perfect amount for 75 people

So the total cheaper cost would $915 while still maintaining a fair amount of seats which is 75

Mr. peter travels 130 miles in 2 hours. at this rate, how many miles will he travel in 30 minutes?
enyata [817]
Alright so basically what you have to do here is realize that 130 miles is 2 hours, so if you divide by 2, you’ll have 65 miles in one hour ,, so 6mph, and if you divide again by two, you have 32.5 miles ,, therefore he travels 32.5 miles in 30 minutes
