An Apple iPad sells for $699.00 on eBay. The markup is 30% on cost. What is the total cost of the iPadsold on eBay?

Answers

The cost of the iPad  sold on eBay is $537.7

The mark up percentage is given by:

Mark up = [(selling price - cost price)/cost price] * 100%

Given that selling price = $699, mark up = 30%= 0.3. Let x represent the cost price, hence:

Mark up = [(selling price - cost price)/cost price] * 100%

0.3 = (699-x)/x

0.3x = 699 - x

1.3x = 699

x = $537.7

Therefore the cost of the iPad  sold on eBay is $537.7

the cost of ipad = 699$
the markup = 30%
1%  = 699/100 = 6.99$
30% = 6.99 x 3 = 209.7$
the markup = 209.7$
the total cost of the ipad = 699 + 209.7 = 908.7$

Solve the following system:y = x + 3
2x + y = 9

(2, 5)
(5, 2)
(−2, 5)
(2, −5)

Answers

Hi,

y = x+3
2x+y = 9

2x+(x+3) = 9
2x+x+3 = 9
3x+3 = 9
3x = 9-3
3x = 6
x = 6/3
x = 2

y = x+3
y = 2+3
y = 5

Answer:

(x,y) = (2,5)

ahhh easy:) all we have to do is plug in y
sooo this question becomes 
2x + x + 3 = 9 
we add the xs and they become 3x
soooo
3x + 3 = 9 
now subtract 3 from both sides
3x +3 = 9 
     - 3 = -3 
they cancel out on the left hand side and the right side of the equal sign becomes a 6 
sooooo
3x = 6 
divide both sides by 3 
3x = 6 
÷3 = ÷ 3
the 3s on the left side cancel out
and the right side becomes 2
sooooo
x = 2 
but before we can answer this completely we plug it into our first equation
soooo
y = x + 3 
to this 
y = 2 + 3 
so y = 5
x = 2 
y = 5

What's the answer 2795÷43

Answers

2795 ÷ 43 = 65

I can give you the answer using long division.

       0065
43 | 2795
       258↓                 43 * 6
         215
         215                 43 * 5
          -0-

the answer is 65 because u have to multiply and then u can divide the numbers that u have there so the answer is 65

Consider the expression –3(y – 5)2 – 9 + 7y.Which statements are true about the process and simplified product? Check all that apply.

A=The first step in simplifying is to distribute the –3 throughout the parentheses.
B=There are 3 terms in the simplified product.
C=The simplified product is a degree 3 polynomial.
D=The final simplified product is –3y2 + 7y – 9.
E=The final simplified product is –3y2 + 37y – 84.

Answers

Answer: Option 'B' and 'E' are correct.

Step-by-step explanation:

Since we have given that

-3(y-y)^2-9+7y

Simplification needs a few steps:

-3(y-5)^2-9+7y\n=-3(y^2+25-10y)-9+7y\n=-3y^2-75+30y-9+7y\n=-3y^2+37y-84

So, Option 'B' and 'E' are correct.

As Option 'B' says there are 3 terms in the simplified product, which is true.

B and E

Answer:

4th Option: All real numbers greater than or equal to 2.

Step-by-step explanation:

Range is the set of y-values that can be outputted by function f(x).

We see here our range spans from 2 to infinity. Since 2 is a closed dot, we can include it in our range. Therefore our answer is All real numbers that are greater than or equal to 2.
