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)

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.
