andrezito [222]

Answer:

$3x+2y=315\\\\2x+4y=450$

is the system of equations representing the situation.

Step-by-step explanation:

Given:

Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2 haircuts and 4 hair dyes takes 450 minutes.

Now, to find the system of equations representing the situation.

Let the number of haircuts be $x.$

Let the number of hair dyes be $y.$

So, Alexandra can give 3 haircuts and 2 hair dyes in:

$3x+2y=315.$

Now, giving 2 haircuts and 4 hair dyes in:

$2x+4y=450.$

Therefore,

$3x+2y=315\\\\2x+4y=450$

is the system of equations representing the situation.

Y = -2x - 4 y = 4x + 2

adoni [48]

The value of x and y in the given equation is determined -1 and -2 respectively.

<h3>Value of x and y</h3>

The value of x and y can be determined by solving the two equations simultaneously.

y = -2x - 4 ----- (1)

y = 4x + 2 ----- (2)

solve (1) and (2) together

-2x - 4 = 4x + 2

-6x = 6

x = -1

y = 4(-1) + 2

y = -4 + 2

y = -2

A carpenter uses 65 shelves to make 13 bookcases. She uses the same number of shelves for each bookcase. Are 32 shelves enough t

ohaa [14]

Hello There!

First work out the number of shelves per bookcase:
65/13 = 5
It is 5 shelves per bookcase.
6 x 5 = 30.
Therefore 32 shelves are enough to make 6 bookcases.

Hope This Helps You!
Good Luck :)
