Solve the following order of operations equation: 120 / (2+4)

When solving this equation you will start from left to right but go in the order of PEMDAS - Parentheses, Exponents, Multiplication and Division and lastly addition and subtraction. Since the 2+4 is in parentheses, we will solve that first. 2+4 = 6 Next we will do the division which is not 120/6 120/6 = 20 The answer to our equation is 20 If you are unable to divide 120/6 in your head or using a calculator, you can use long division. 6 l 120 you look at the 6 and see how many times it can go into the first number. . 6 can go into 12 twice. You would put a 2 above the 12 and then multiply 6X2 = 12. 12-12 = 0 You would then move onto the next number. The next number is 0 and 6 doesn't go into 0 so you would put a 0 above the 0 like below: 20 6 l 120 12 0 0 The number on top tells us that 120/6 = 20

### Subject: Accounting

Given the following information, what is the Gross Margin, Net Income? Sales - $850,500 COGS - $470,000 Selling Expenses - 50,000 Admin Expenses - 15,000 Depreciation - $20,000 Interest Revenue - $18,000 Current Assets - $1,050,400 Current Liabilities - $600,300

Sales - COGS(or Cost of Goods Sold) = Gross Margin: 850,500 - 470,000 = 380,500 Gross Margin = $380,500 To find the net income we will start will sales and subtract COSG to find the gross margin, which we have already done. Next we will subtract out operating expenses and other income and expenses to find the net income Sales $850,500 COGS $470,000 Gross Margin $380,500 Operating Expenses: Selling Expenses $50,000 Admin Expenses $15,000 Depreciation $20,000 Total Operating Expenses: $85,000 Operating Income: $295,500 Other Income and Expenses: Interest Expense $18,000 Total Other Income and Exps: $18,000 Net Income: $277,500 From this example we are able to see how it works down from Sales to Net Income. We have to subtract COGS, Operating and other Expenses out of Sales to get to Net Income. Although assets and liabilities were included, they are not used to determine the net income. Assets and liabilities belong on the balance sheet, not the income statement.

### Subject: Algebra

Solve for X √(X-10)=3

To solve this equation you will start by squaring both sides. - (√(X-10))^2=(3)^2 After squaring both side you are left with X-10 = 9. Which seems much easier to solve, right? From here, you will add the 10 to both sides. Leaving, X = 19 Another way you can check your answer is by plugging the 19 into the original equation. √(19-10)=3 √(9) = 3 3=3
