Answer:

y = 15 and x = 22

Step-by-step explanation:

700 = 25x + 10y

x = y + 7

700 = 25(y +7) + 10y

700 = 35y + 175

525 = 35y

15 = y

700 = 25x + 150

550 = 25x

22 = x

Solve 4|x + 6| = 16
Galina-37 [17]

4 | x + 6 | = 16

Divide both sides by 4.

\bf{\dfrac{4|x+6|}{4}=\dfrac{16}{4}   }

\bf{|x+6|=4 }

Absolute value is solved.

\bf{|x+6|=4 }

We know either x + 6 = 4 or x + 6 = -4.

<u>                                                                        </u>

x + 6 = 4 (Possibility 1)

x + 6 - 6 = 4 - 6 (Subtract 6 from both sides)

x=−2

<u>                                                                        </u>

x + 6 = -4 (Possibility 2)

x + 6 - 6 = -4 - 6 (Subtract 6 from both sides)

x=-10

Solution:

x=−2 or x=−10

sveticcg [70]

Answer:

a. Haricot: 45 million

Pinto: 41.4

b. Haricot:

debtholders: 0

shareholders: 105 million

Pinto:

debtholders: 12 millipon

shareholders: 96.6 million

Step-by-step explanation:

We have to:

a.

Tax on Haricot 150 * 30% = 45

that is 45 million

interest on debt of Pinto = 200 * 6% = 12

that is to say 12 million

Profit of Pinto 150 million less the interest that would be 12 million

150 - 12 = 138

we calculate the tax

138 * 30% = 41.4 million

Therefore Tax amount

Haricot = 45 million

Pinto = 41.4 million

B.

return to shareholders of Haricot = 150 - 45 = 105 million

return to shareholders of Pinto = 150 - 12 - 41.4 = 96.6 million

Also:

return to debtholders of Haricot = 0

return to debtholders of Pinto = 12 million
