A diner makes 26 pizza crusts the first week of summer and 90 pizza crusts each subsequent week. In how many weeks will the total number of pizza crusts made by the pizza parlor be twice the total number of pizza crusts made by the diner?

The total number of pizza crusts made by the pizza parlor will_______

Answers

Answer:

  • Every week

Step-by-step explanation:

Let the number of weeks be x, then equations

Pizza parlor

  • 52 + 180x

Diner

  • 26 +90x

In how many weeks will the total number of pizza crusts made by the pizza parlor be twice the total number of pizza crusts made by the diner?

  • 52 + 180x = 2(26 +90x)
  • 52 + 180x = 52 + 180x
  • 0 = 0

This results means that every week pizza parlor makes twice the number of by diner

Answer:

\large \boxed{\sf always \ be \ double \ than \ the \ diner}

Step-by-step explanation:

Let x  represent the no. of weeks

Pizza parlor:  180x + 52

Diner:  90x  + 26

Write the equation and solve for x

180x + 52 = 2(90x  + 26)

x  = x (TRUE)

The total number of pizza crusts made by the pizza parlor will always be double than the diner.

Use the form y=mx +b for linear equations.Write the equation for the following relation.C = {(x, y): (6, 15), (8, 21), (10, 27), . . .}

Answers

I'm not sure if the answer is right, but here you go.

y=mx+b 

'm' is for gradient of the line. First, calculate the gradient.

Let's use (6,15) and (8,21)

Gradient, m = y_(2) - y_(1)
                    --------------
                     x_(2) - x_(1)
                 
                 =  21 - 15     = 6       = 3
                     -----------      ----   
                       8 - 6         2
           
Therefore, m = 3 . Now let's search 'b' .
Let's use (6,15) again. Substitute it into the equation.

y=mx+b 
15 = 3 (6) + b
b = -3

Thus, the equation : y=3x -3

Apartment A rents for $600 per month and includes heat and electric. Apartment B rents for $400 per month but heat and electric are not included. Electric averages $40 per month. Heat costs for last year totaled $800. Which apartment is cheaper?

Answers

Appartment B is cheaper. Explanation: we need to compare these two values. A = 600 and B = 400 + cost of heat per month + cost of electricity per month. The cost of heat per year is 800, which gives us a monthly cost of 800/12 = ~$67. So the rent cost for appartment B is 400 + 40 + 67 or 507, which is less than 600.
