Combining like terms is combining numbers with the same variables.

= -14 + 12 + 9z - 16z

= (-14 + 12) + (9z - 16z)

= -2 - 7z

~Put into standard form

-7z - 2

Best of Luck!

Answer:

-6/7

Step-by-step explanation:

-14+12+9z-16z=0

-6-7z=0

Add 7z to both sides

-6=7z

Divide both sides by 7

z=-6/7

Therefore the value for z is -6/7

The adjusted trial balance of Blue Spruce Corp. Shows these data pertaining to sales at the end of its fiscal year, October 31,

Tema [17]

The preparation of the Sales section of the income statement for Blue Spruce Corp. is as follows:

BLUE SPRUCE CORP.

<h3>Income Statement</h3>

For the year ended October 31, 2022

Sales Revenue $908,400

Sales Returns and Allowances (20,900)

Sales Discounts (14,700)

Net sales revenue $872,800

<h3>How makes up the net sales revenue?</h3>

The net sales revenue represents the gross revenue minus sales returns and allowances and sales discounts.

In most jurisdictions, the sales discount account is reported on the income statement as a contra revenue account. This implies that sales discounts are directly deducted from the gross sales and do not appear in the expense section nor the notes to the sales or revenue.

<h3>Data and Calculations:</h3>

Sales Revenue $908,400

Freight-Out $12,600

Sales Returns and Allowances $20,900

Sales Discounts $14,700

Thus, the preparation of the sales section of the income statement for Blue Spruce Corp. shows a net sales revenue of $872,800.

Can somebody help me with this!?

Answer:

24 $\pi$ /5

Step-by-step explanation:

The way I think about areas of sectors is a fraction of the pie. You know what percentage of the "pie" (in this case, circle) you want, because they give you the angle of the sector and you know a circle always has 360°. So technically, you're trying to find 48/360 th of the entire area (36 $\pi$ ). If you're using a calculator, it doesn't matter if you simplify the fraction, but if you're doing it by hand simplifying makes everything a lot easier.

The equation will be:

Area = 24/180 × 36 $\pi$

= 2/15 × 36 $\pi$

= 72 $\pi$ /15

= 24 $\pi$ /5

I hope this helped! Also, in Khan Academy, when you get an answer wrong/right, you can view their explanation by clicking "hint" or sometimes "see how we did it" shows up.
