7x-(x-y) = 7x - x + y = 6x + y

9a-(2b-a) = 9a+a-2b = 10a-2b

hope it helped

Since there's a - next to the bracket, you minus everything inside of it, if there's a minus in the bracket, it turns to +
7x-(x-y) = 7x-x+y = 6x+y
9a-(2b-a) = 9a-2b+a = 10a-2b

Reporting Stockholders' Equity
DaniilM [7]

The total stockholders equity based on the information given will be $8285000.

<h3>How to compute the equity?</h3>

The stockholders equity will be calculated thus:

Common stock $4480000

Excess over par = $1152000

Paid in capital = $5632000

Sale of treasury = $224,000

Total paid in capital = $5856000

Retained earnings = $2,554,000

Total = $8,410,000

Less treasury stock = 125,000

Total stockholders equity = $8,410,000 - $125000

= $8285000

Therefore, the total stockholders equity based on the information given will be $8285000.

Angle ABD=87 degrees
angle ABC+angle CBD= angle ABD
Therefore, 9x-1+6x+58=87
15x+57=87
15x=87-57
15x=30
x=30/15
x=2   


Angle ABC= 9x-1
=9(2)-1
=18-1
=17 degrees
