Santa's elves are selling

Andreas93 [3]

cost of one peppermint cookies = $ 0.6

cost of one cinnamon sugar cookies = $ 0.3

<h3><u>Solution:</u></h3>

Let "p" be the cost of one peppermint cookies

Let "c" be the cost of one cinnamon sugar cookies

<u><em>To find: cost of each cookie</em></u>

<h3><u><em>On the first day, they sold 120 peppermint cookies and 30 cinnamon sugar cookies for a total of $81</em></u></h3>

We can frame a equation as:

120 peppermint cookies x cost of one peppermint cookies + 30 cinnamon sugar cookies x cost of one cinnamon sugar cookies = $ 81

$120 \times p + 30 \times c = 81$

120p + 30c = 81 --------- eqn 1

<h3><u><em>The next day they made $60 by selling 70 peppermint cookies and 60 cinnamon sugar cookies</em></u></h3>

70 peppermint cookies x cost of one peppermint cookies + 60 cinnamon sugar cookies x cost of one cinnamon sugar cookies = $ 60

$70 \times p + 60 \times c = 60$

70p + 60c = 60 --------- eqn 2

Let us solve eqn 1 and eqn 2 to find values of "p" and "c"

Multiply eqn 1 by 2

240p + 60c = 162 --- eqn 3

Subtract eqn 2 from eqn 3

240p + 60c = 162

70p + 60c = 60

(-) -------------------------

170p = 102

<h3>p = 0.6</h3>

Substitute p = 0.6 in eqn 1

120p + 30c = 81

120(0.6) + 30c = 81

72 + 30c = 81

30c = 9

<h3>c = 0.3</h3>

<u><em>Summarizing the results:</em></u>

<em>cost of one peppermint cookies = $ 0.6</em>

<em>cost of one cinnamon sugar cookies = $ 0.3</em>

Voce 2x-u - 1x2-3x+3 = 2

kumpel [21]

Answer:

u=−x2−x+1

Step-by-step explanation:

Let's solve for u.

2x−u−1x^2−3x+3=2

Step 1: Add x^2 to both sides.

−x2−u−x+3+x2=2+x2

−u−x+3=x2+2

Step 2: Add x to both sides.

−u−x+3+x=x2+2+x

−u+3=x2+x+2

Step 3: Add -3 to both sides.

−u+3+−3=x2+x+2+−3

−u=x2+x−1

Step 4: Divide both sides by -1.

−u/−1=x2+x−1

−1/u=−x2−x+1

Answer:

u=−x2−x+1

Ethan went to the store and purchased a new DVD player and some movies fro $532. Th cost of the movies was 3 times as much as th

Juliette [100K]

The equation is provided below:

x = cost of DVD player
3x = cost of the movies
$532 = total amount purchased for the DVD player and the movies

$532 = x + 3x
$532 = 4x
$532 / 4 = 4x / 4
$133 = x (cost of the DVD player)

$133 * 3 = $399 (cost of the movies)

To check if the equation is correct:

$532 = $133 + ( 3 * $133)
$532 = $133 + $399
$532 = $532

The correct answer for the cost of the movies will be $399.

Complete the solution of the equation. Find the value of y when x equals 6. -x+7y=8.

Maslowich

X=6

-6+ 7(y) = 8
-6 + 7(2)
-6 + 14
You subtract when adding a positive and negative number
Since the positive number is higher, your answer will be positive.

-6 + 14 = 8
