A) A mark dwon greater than 99% and less than 100%

Mark down 99.1% of x

Original price: x

Final price: original price - mark down = x - 0.991 x = 0.009x

=> If orginal price is 1000 and mark down is 99.1% , final price = 0.009*1000 = 9

You can check that the mark down is 99.1% of 1000 = 991.

b) A mark down that is less than 1%

Mark down: 0.1%

Original price: 10,000

Mark down: 10,000 * 0.1% = 10

Final price: 10,000 - 10 = 9,990

c) A mark up that is more than 200%

Mark up: 300%

Original price: 100

=> final price = 100 + 100*300% = 100 + 300 = 400

5/10 = /6 is 5/10 and 3/6 equivalent fraction. if so, please explain

Sonja [21]

$\frac{5}{10}= \frac{1\cdot5}{2\cdot5} = \frac{1}{2} \ \ \ and\ \ \ \frac{3}{6}= \frac{1\cdot3}{2\cdot3} = \frac{1}{2} \ \ \ \ \Rightarrow\ \ \ \frac{5}{10}=\frac{3}{6}$

Amber is on a family cell phone plan with 2 other family members. The family gets 720 shared cell phone minutes a month, each fa

chubhunter [2.5K]

Amber plus 2 family members = 3 total people on the plan.

They share the minutes equally so divide the minutes by 3 to find how many she can use:

720 / 3 = 240 minutes per month.

Now divide the monthly minutes by 30 days:

240 / 30 = 8 minutes per day.

Which expression has a value of 15 when n = 7? 43 minus 5 n 3 n minus 5 6 n minus 28 19 minus StartFraction 28 Over n EndFractio

andrey2020 [161]

Answer:

$19-\dfrac{28}{n}$ is the expression with value of 15 when n = 7.

Step-by-step explanation:

To find the expression whose value is 15, substitute the value of n = 7 in each given expression.

Expression 1:

$43-5n$

Substituting the value of n,

$43-5\left(7\right)$

Simplifying,

$43-35=8$

Since the value of the expression is 8 which is not equal 15.

Hence expression $43-5n$ does not have value of 15 when n = 7.

Expression 2:

$3n-5$

Substituting the value of n,

$3\left(7\right)-5$

Simplifying,

$21-5=16$

Since the value of the expression is 16 which is not equal 15.

Hence expression $3n-5$ does not have value of 15 when n = 7.

Expression 3:

$6n-28$

Substituting the value of n,

$6\left(7\right)-28$

Simplifying,

$42-28=14$

Since the value of the expression is 14 which is not equal 15.

Hence expression $6n-28$ does not have value of 15 when n = 7.

Expression 4:

$19-\dfrac{28}{n}$

Substituting the value of n,

$19-\dfrac{28}{7}$

Simplifying,

$19-4=15$

Since the value of the expression is 15 which is equal 15.

Hence expression $19-\dfrac{28}{n}$ has the value of 15 when n = 7.

Answer:

y= $\frac{5}{6}$ x-2

Step-by-step explanation:

Using the formula rise/run I calculated the slope. Then I saw the line passes through the point in the y axis -2. So the equation would be y=5/6x-2
