Marle placed two orders at the same restaurant last month. in one order, she received 5 trays of lasagna and 3 trays of
garlic bread for $163. in the other order, she received 4 trays of lasagna and 4 trays of garlic bread for $150.80. what is
the price for one tray of lasagna, l, and one tray of garlic bread, g?

$25.25-lasagna, $12.25-garlic bread

Step-by-step explanation:

  5L+3G=163

- 4L+4G=150

 4(5L+3G=163)

-5(4L+4G=150)

20L+12G=652

-20L-20G=-750

          -8G=-98

         -8G/-8 = -98/-8

               G=$12.25

now plug that into G in any of the 2 equations at the top and you can solve for L(price of lasagna)

other answer is correct. i had used the radius of the radius somehow. a website:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
