Answer:

The simplified form of the given expression is 18x^2+19x+35.

Step-by-step explanation:

The given expression is

5(7-x)+6x(3x+4)

We need to find the simplified form of the given expression.

Using distributive property we get

5(7)+5(-x)+6x(3x)+6x(4)

On further simplification we get

35-5x+18x^2+24x

On combine like terms.

18x^2+(-5x+24x)+35

18x^2+19x+35

Therefore the simplified form of the given expression is 18x^2+19x+35.

Len [333]

Answer:

   a) The cost of ribeye steak dinners is $ 16.96.

   b) The cost of grilled salmon dinners is $ 23.37.

Explanation:

 Let the cost for ribeye steak dinners  be m and cost for grilled salmon dinners  be n.

 A waitress sold 10 ribeye steak dinners and 18 grilled salmon dinners, totaling $590.39 on a particular day.

So, we have    

         10 m + 18 n = 590.39 -------equation 1

Another day she sold 22 ribeye steak dinners and 9 grilled salmon dinners, totaling $583.49

So, we have    

         22 m + 9 n = 583.49 -------equation 2

 equation 2 x 2

       44 m + 18 n = 1166.98 -------equation 3

 equation 3 - equation 1

        44 m + 18 n - (  10 m + 18 n ) = 1166.98 - 590.39

         m = 16.96 $

  Substituting in equation 1

        22 x 16.96 + 9 n = 583.49

          n = 23.37 $

   a) The cost of ribeye steak dinners is $ 16.96.

   b) The cost of grilled salmon dinners is $ 23.37.
