Algebra 1, word problem. if a medium pizza costs $5 and a large pizza is $8, write an equation in standard form that models the possible combinations if you have $45. (let m= medium and l= large.) explain in detail

m = number of medium pizzas; each medium pizza costs $5

5m = cost of m number of medium pizzas

L = number of large pizzas; each large pizza costs $8

8L = cost of L number of large pizzas

The total cost is the sum of the cost of the medium pizzas and the cost of the large pizzas, so the total cost is 5m + 5L.

You have $45, so the total cost of the pizzas must equal $45.

The equation is

5m + 8L = 45

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
