A store is having a sale in which all items are marked30%off.4a.) Which equation represents the selling price,s, in dollars, of an item originally pricedpdollars after a markdown of30%?

Answer: x=48

Step-by-step explanation:

first add 9 to both sides

then add 27 to 9 to get 36

multiply both sides by 3/4 the reciprocol of 4/3

and youll get x=36 x (4/3)

simply to a single fraction then

then divide 144 by 3  to get 48

Answer:

X= 10/3y + -4/3                

Step-by-step explanation:

Step One: add -5y to both sides

Step two: divide both sides by -3

Answer:

-x=1 1/3

Step-by-step explanation:

x-(4x-5y)=(5y+4)

x-4x+5y=5y+4

-3x+5y=5y+4

5y-5y=0

-3x=4

x=4÷3

4÷3=1 1/3

Answer:

(x + 3) + (x + 3) + (x + 3) + (x + 3)

Step-by-step explanation:

Repeated addition:

4(x + 3), means that (x + 3) is added by itself 4 times.

So:

(x + 3) + (x + 3) + (x + 3) + (x + 3)

The questions aren't well formatted ; from the values that are observable,

Answer:

Coefficient of x = -9.9 ;

Coefficient of x = 75

Coefficient of y = 275

Step-by-step explanation:

Given :

0.8 (2x + x) + 3(7 - 4.1x) = __x + 21

0.8(3x) + 21 - 12.3x = __x + 21

2.4x + 21 - 12.3x = __x + 21

-9.9x + 21 = __x + 21

-9.9

12 1/2 (6x + 22y) = x + y

75x + 275y = x + y

Answer:

The answers are:

1.  -9.9x

2.  3x + 11y

3.  1

A. biased; convenience sample

Step-by-step explanation:

Alana is reading the first 17 pages, which are what is most conveniently available.

The sample of the assigned reading likely to be biased and convenience sample.

probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.

Given:

Alana skimmed the first 17 pages from each of the books

assigned in her literature class. Each assigned book has an equal number of pages.

According to given question we have

A biased estimator is one that deviates from the true population value. A biased sample can still be useful if the nature of the bias and how much of a bias exists is known.

An unbiased estimator is when a value from a sample is the same as the actual value of a population parameter.

The sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalizations from your sample to the population you are studying.

Therefore, the sample of the assigned reading likely to be biased and convenience sample.

Step-by-step explanation:

[tex]x^{0} = 1\\\\\frac{x^{m}}{x^{n}}= \frac{1}{x^(n-m)}}, n >m\\\\\\\frac{6ab}{(a^{0}b^{2})^{4}}=\frac{6ab}{(1*b^{2})^{4}}\\\\=\frac{6ab}{b^{2*4}}\\\\=\frac{6ab}{b^{8}}\\\\=\frac{6a}{b^{8-1}}\\\\=\frac{6a}{b^{7}}[/tex]

The equivalent expression of 6ab/(a^0b^2)^4 is 6a/b^7

The expression is given as:

6ab/(a^0b^2)^4

Evaluate the exponent of 0

Answer:

$0.22

Step-by-step explanation:

Ellen has a coupon of 1.55 off a loaf of bread

The regular price of the bread is 4.63, the loaf is cut into 14 slices

Therefore if she uses her coupon the price per slice can be calculated as follows

= 4.63-1.55

= 3.08

3.08/14

= 0.22

Hence the price is $0.22

Answer:

$49.6

Step-by-step explanation:

Given that :

Wholesale price, p = $32

Markup percentage = 55%

Selling price = wholesale price * ( 1 + Markup percentage)

Selling price = $32(1 + 0.55)

Selling price = $32(1.55)

Selling price = $49.6

Hope that helped

I'm not sure if that's right

Answer:

I'm pretty sure you just divide 31 with 20 and then you get 1.55 and after you get 1.55 you multiple that by 100 to get 155% which will be the percent you need

19th term = ar^18

19th term = 774,840,978

Step-by-step explanation:

First term, a = 2

Common ratio, r = 3

nth term of a geometric sequence = ar^(n-1)

19th term = ar^(19-1)

19th term = ar^18

= 2 × 3^18

= 2 × 387,420,489

= 774,840,978

19th term = 774,840,978

Answer:

Step-by-step explanation:

Use the distance formula:

d = [tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]

Points of the diagonal: (-2, -2) and (2, 4)

d = [tex]\sqrt{(2-(-2))^2+(4-(-2))^2}[/tex]

d = [tex]\sqrt{(2+2)^2+(4+2)^2}[/tex]

d = [tex]\sqrt{(4)^2+(6)^2}[/tex]

d = [tex]\sqrt{16 + 36}[/tex]

d = [tex]\sqrt{52}[/tex]
