Answer:

n = -7

Step-by-step explanation:

You do cancels and removal out by inverse operation to find the answer.

Step 1: Write out the equation.

n+16=9

Step 2: Subtract both sides by 16 to cancel out the positive 16.

n +16 (-16) = 9 -16

Step 3: After +16-16, 9-16, you shall not have any more operations like (+, -, *, or / )

n = -7

*Note:

n = -7.

2n = -14.

Three friends decide to evenly split their bill at a restaurant. The total bill is $84.99 and they will have to pay an additiona

xz_007 [3.2K]

Given : The Total Bill at the Restaurant is $84.99

Given : The Additional Tax is $5.10

⇒ Total Bill Including the Tax is : (84.99 + 5.10) = $90.09

Given : Three Friends decide to evenly split their Bill

⇒ $90.09 should be Divided into 3 Equal Parts

$\mathsf{\implies The\;Amount\;each\;person\;should\;owe\;is = (\frac{90.09}{3})}$

$\mathsf{\implies The\;Amount\;each\;person\;should\;owe\;is = 30.03\;Dollars}$

His Friend Calculation is not Reasonable

elena55 [62]

$\frac{(45)^2}{78}$

To solve the problem find the value of (45)^2 at first

$(45)^2=2025$ $\frac{2025}{78}=25\text{ R75}$

The answer is 25 with the remainder 75

$25\frac{75}{78}$

You can simplify the fraction to be 25/26

$25\frac{25}{26}$

Answer:

the markup percentage is 66.67%

Step-by-step explanation:

The computation of the percent of markup based on cost is shown below:

= (Selling price - paid price) ÷ (paid price)

= ($15 - $9) ÷ ($9)

= 66.67%

By taking the difference of the selling price & paid price and then divided it by paid price we can get the percentage of markup

Hence, the markup percentage is 66.67%
