Answer:

There are infinite solutions to this problem

Step-by-step explanation:

The equations are scale multiples of each other...

Take the first equation and subtract x from both sides...

y = x + 5    becomes

-x + y = 5

Now divide the equation by -1...

x - y = -5

Now multiply the equation by 4....

4x - 4y = -20

This is now the same as equation 2.  The lines lay on top of each other, so there are infinite points (x, y) that will solve this equation, what ever value 'x' is, 'y' will be 5 values higher

(0, 5)

(1, 6)

(5, 10)

Are some examples

vova2212 [387]

Answer:

Brother is 70.5 and sister is 64.5

Step-by-step explanation:

you will need to set up a simple equation and give out variables.

Girls age = 6-x

Brother's age= x

the you will take those 2 and add them and place them equal to 135:

6-x+x=135

6-2x+6=135+6

The 6 cancels out

2x=141

2x/2=141/2

x=70.5

The brother's age would be 70.5 then and the girl's would be 64.5

Feliz [49]

Answer:

The correct option is D.

Step-by-step explanation:

Given information:

On June 2 : Dreamtime Laundry purchased $7,000 worth of supplies.

On June 30 : An inventory of the supplies indicated only $2,000 on hand.

The adjusted amount is

\$7,000-\$2,000=\$5,000

To adjust the amount we need to debit Supplies Expense by $5000 and credit Supplies by $5,000.

So, the required adjusting entry that should be made by the company on June 30 is

Supplies Expense        $5,000

             Credit Supplies           $5,000

Therefore, the correct option is D.
