Solve this system of equations using the Substitution method. 3x + y = -2 y = 2x + 3

Mathematics
1 answer:

Answer:

Step-by-step explanation:

we see that y = -3x-3

substitute that into the other equation to get

-3x-3 = 2x+7

-5x = 10

x = -2

so, y = -3(-2)-3 = 3

check to make sure (-2,3) solves both equations.

How many full bowls of guacamole can be made with 15 avocado
Digiron [165]

A recipe calls for 3 avocados for each bowl of guacamole.

Let avocados = a, guacamole = g:

g = a/3

You have 17 avocados. Plug in 17 for a

g = 17/3

g = 5.66 (continuing).

However, they are asking for only "full bowls", which means you will not count any parts, and you will not round.

5.66 will become 5

-------------------------------------------------------------------------------------------------------------------

5 is your answer

hope this helps
