Answer:

see explanation

Step-by-step explanation:

(1)

Given

- 2x = x² - 6 ( subtract x² from both sides )

- x² - 2x = - 6 ( multiply through by - 1 )

x² + 2x = 6

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(1)x + 1 = 6 + 1

(x + 1)² = 7

(2)

Take the square root of both sides

x + 1 = ± \sqrt{7} ( subtract 1 from both sides )

x = - 1 ± \sqrt{7}

Solutions are x = - 1 - \sqrt{7} , x = - 1 + \sqrt{7}

Alla [95]

Answer:

There would be 9 cups of sugar with 6 cups of cocoa in the cake

Step-by-step explanation:

Put the 3 cups of sugar on top and then put a line below it to make it a ratio and then put the 2 cups of cocoa powder. Multiply cups of cocoa by 3 to make 6 cups of cocoa. Then since you multiplied the bottom you also need to multiply the top by 3, so you would multiply the 3 cups of sugar by 3 to get 9 cups of sugar in his cake.

Intercontinental, Inc., uses a perpetual inventory system. Consider the following information about its inventory: July 1, purch
salantis [7]

Answer:

Using weighted average, the cost of goods sold for the sale of 23 units on July 31 is $2,504.70, and the inventory balance at July 31 is $ 1,306.90.

Step-by-step explanation:

Since Intercontinental, Inc., uses a perpetual inventory system, and on July 1, purchased 10 units for $ 910 or $ 91 per unit; on July 3, purchased 15 units for $ 1,590 or $ 106 per unit; on July 14, it sold 20 units; on July 17, purchased 20 units for $ 2,300 or $ 115 per unit; on July 28, purchased 10 units for $ 1,190 or $ 119 per unit; and on July 31, sold 23 units, to determine the average costs and the inventory balance as of July 31, the following calculations must be performed:

(910 +1590 + 2300 + 1190) / (10 + 15 + 20 + 10) = X

5990/55 = X

108.90 = X

108.90 x 23 = 2504.7

(55 x 108.9) - (43 x 108.9) = X

5990 - 4683.10 = X

1306.90 = X

Using weighted average, the cost of goods sold for the sale of 23 units on July 31 is $ 2504.70, and the inventory balance at July 31 is $ 1,306.90.
