Answer:

1. 44 + 3x

2. 2y - 8

3. x - 6

15. 5\frac{7}{8}

16. 6\frac{1}{3}

17. 3\frac{7}{9}

Step-by-step explanation:

1. 7² + 2² - 5 - 4 + 3x

   49 + 4 - 5 - 4 + 3x

       53 - 5 - 4 + 3x

           48 - 4 + 3x

              44 + 3x

2. - y - 5 + y + 2(2y-y) - 3

     -y - 5 + y + 4y - 2y -3

      -y - 5 + 5y - 2y - 3

          4y - 2y - 5 - 3

                2y - 8

3. 5x -3 - x - 3(x + 1²)

    5x - 3 - x - 3x - 3

      4x - 3x - 3 -3

           x - 3 -3

             x - 6

15.  7\frac{1}{4} - 1\frac{3}{8}

   = 7 \frac{2}{8} - 1\frac{3}{8}

   = \frac{58}{8} - \frac{11}{8}

   = \frac{47}{8} → 5\frac{7}{8}

16.  9 - 2\frac{2}{3}

   = \frac{54}{6} - 2\frac{4}{6}

   = \frac{54}{6} - \frac{16}{6}

   = \frac{38}{6} → 6\frac{2}{6} → 6\frac{1}{3}

17.  10\frac{1}{3}  - 6\frac{5}{9}

   =  10 \frac{3}{9} - 6\frac{5}{9}

   =    \frac{93}{9} - \frac{59}{9}

   =     \frac{34}{9} → 3\frac{7}{9}

Hope this helps.

A school group wants to rent part of a bowling alley to have a party. The bowling alley costs $500 to rent, plus an additional c
Firlakuza [10]

Answer:

If there are N students, the total cost will be:

C(N) = $500 + $5*N.

And we want the amount that each student pays to be equal or less than $15.

then:

C(N)/N ≤ $15.

Then the inequality that represents this situation is:

($500 + $5*N)/N ≤ $15.

Now, let's solve this:

($500 + $5*N) ≤ $15*N

$500 ≤ $15*N - $5*N

$500 ≤ $10*N

$500/$10 ≤ N

50 ≤ N

So the minimum number of students needed is 50.
