Monica built a porch that contained 2 different colors of bricks to create a pattern. she purchased the red bricks for $7 each and the gray bricks for $4 each. write a system to find out how many red bricks monica purchased if she spent $193 on 40 bricks?

a. what is the system that models this situation?
equation #1:
equation #2:

b. how many red bricks did monica purchase?

a.

b. 11 red bricks

Step-by-step explanation:

Let x be the number of red bricks and y be the number of grey bricks.

1. Monica purchased 40 bricks, so

2.  If she purchased the red bricks for $7 each, then x red bricks cost $7x. If the gray bricks are for $4 each, then y bricks cost $4y. In total, all bricks cost $(7x + 4y) that is $193. Hence,

a. The system of two equations is

b. From the first equation:

Substitute it into the second equation:

Monica purshased 11 red bricks and 29 grey bricks.

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
