Answer:

x=1 y=0

Step-by-step explanation:

y + 2 = 2x y = 2x - 2

y + 2x = 2

(2x - 2) + 2x = 2

4x = 4

x = 1

y + 2 = 2(1)

y + 2 = 2

y = 0

what is a number of 3 digits and multiple of 5 but less than 600 and can be formed from 1,3,5,7 and 9?

Murljashka [212]

Any multipule of 5 ends with either a 0 or a 5

so we see that ther are no 0's in the list so it must end with 5

so the other 2 digits can be any number
wait, less than 600
so the first digit can be 1 or 3

some possible numbers are

135
175
195
315
375
395

those are the possible numbers

Once upon a time, there was a former whose family raised pigs and chickens. One morning, the farmer's wife looked into the barny

Fed [463]

Using a system of equations, it is found that:

There are 8 chickens in the yard.

There are 16 pigs in the yard.

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

This question is solved using a system of equations. I am going to say that:

x is the number of chickens.

y is the number of pigs.

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

A chicken has 1 head, as do a pig.
There are 24 heads.

Thus:

$x + y = 24 \rightarrow y = 24 - x$

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

A chicken has 2 feet.
A pig has 4 feet.
In total, there are 80 feet.

Thus:

$2x + 4y = 80$

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

Number of chicken:

Since $y = 24 - x$

$2x + 4y = 80$

$2x + 4(24 - x) = 80$

$2x + 96 - 4x = 80$

$2x = 16$

$x = \frac{16}{2}$

$x = 8$

There are 8 chickens in the yard.

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

Number of pigs:

$y = 24 - x = 24 - 8 = 16$

There are 16 pigs in the yard.
