2x+3y = 15 x-3y=3 Solve

Mathematics
1 answer:
Arada [10]3 years ago

By process of elimination. 3y and -3y get eliminated. Giving you

3x=18

Divide by 3 on each side

Giving you x=6

Plugging it into equation 2 you get

(6)-3y=3

Taking out the parenthesis you have

6-3y=3

Subtract by 6 on each side giving you

-3y=-3

Divide by -3 on each side giving you

y=1

So the answer for this equation is x=6 and y=1 or the ordered pair (6,1)

Can you completely over a 4 ft by 8 ft area with 3 ft by 3 ft tiles?
Vika [28.1K]

Yes, but not without cutting some of the tiles into smaller pieces.

The length of the area is 8-ft.  That's (2 and 2/3) tiles long.

The width of the area is 4-ft.  That's (1 and 1/3) tiles wide.

So you can't just put down rows and columns of whole tiles
and cover the whole area.
______________________________________

Another way to look at it:

-- The area of the whole big plot is  (8 x 4) = 32 square feet.

-- Each tile covers (3 x 3) = 9 square feet.

-- You can't cover 32 square feet with 9-square-feet pieces.
Either you have to cut something off, or else you have to let
something hang outside of the lines.

I need to know question 8 I’m confused
marissa [1.9K]

Remark

Let the pigs = p

Let the chickens = c

Givens

30 heads is another way of saying that there were 30 creatures in the barnyard. In addition each chicken has 2 legs and each pig has 4

c + p = 30

2C + 4P = 100       (2) Divide (2) by 2

C + 2P = 50           (3)  Subtract (1) from (3)

<u>C + P    = 30</u>

       P  = 20

So there were 20 pigs.
