A equation is an algebraic equation of the shape y=mx+b. involving only a continuing and a first-order (linear) term, where m is that the slope and b is that the y-intercept.

From the given information:

He fumigated 3 rooms in one house, 2 in another, and 4 in an exceedingly third.

Then

Landon Elliott takes charges to fumigate each room = $21.95

He fumigated rooms on Monday  = 3 + 2 + 4 = 9 rooms

His total charges = 21.95 × 9

His total charges= $197.55.

So, The total charges are $197.55.

Answer:

The main answer: $4.84

Step-by-step explanation:

County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$75 * 0.0725 = $5.4375

Add the original price and the sales tax.

$75 + $5.4375 = $80.4375

County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!

$70 * 0.08 = $5.6

Add the original price and the sales tax.

$70 + $5.6 = $75.6

Then take the difference.

80.4375 – 75.6 = 4.8375

Round to the nearest hundredth: $4.84

Explanation:

We know that whoever is selected, they are male. So we only focus on the "male" row. There are 4 males who like talking on the phone out of 22 males total. Divide the two values and reduce as much as possible.

4/22 = (2*2)/(2*11) = 2/11

Note a pair of '2's cancel.

The simplified expression for the given algebraic expression [tex]a^{2} c^{2} -b^{2} c^{2} -4a^{2} d^{2} +4b^{2} d^{2}[/tex] is [tex](a+b)(a-b)(c+2d)(c-2d)[/tex]

As per the question statement, we are given an algebraic expression

[tex]a^{2} c^{2} -b^{2} c^{2} -4a^{2} d^{2} +4b^{2} d^{2}[/tex] and we are supposed to solve and simplify it.

Solution:

[tex]a^{2} c^{2} -b^{2} c^{2} -4a^{2} d^{2} +4b^{2} d^{2}\\c^{2} (a^{2} -b^{2})-4d^{2}(a^{2} -b^{2})\\(a^{2} -b^{2})(c^{2}-4d^{2})\\(a^{2} -b^{2})(c^{2}-(2d)^{2})\\[/tex]

Have used Distributive property for solving and simplifying the above algebraic expression.

Now using the property, [tex]a^{2} -b^{2} =(a+b)(a-b)[/tex]

We get,

[tex](a+b)(a-b)(c+2d)(c-2d)[/tex]

Therefore [tex](a+b)(a-b)(c+2d)(c-2d)[/tex] is our required answer.

Answer:

50 hombres y 25 mujeres

Step-by-step explanation:

Sea m el número de hombres y w el número de mujeres.

El total es 75

Así; m + w = ​​75 •••••••• (i)

Además; 16% de m + 20% de w = 13

0,16 m + 0,2 w = 13

Multiplicar por 100

16m + 20w = 1300 ••••• (ii)

De i, m = 75-w 16 (75-w) + 20w = 1300

1200 - 16w + 20w = 1300

4w = 1300-1200

w = 100/4 w = 25

Recordar; w + m = 75

25 + m = 75

m = 75-25

m = 50

Answer:

-4/13

Step-by-step explanation:

Answer: x = -4/13

Step-by-step explanation:

8x + 1 = 21x + 5

8x + 1 - 21x = 21x +5 - 21x

-13x + 1 = 5

-13x + 1 - 1 = 5 - 1

-13x/13 = 4/-13

x = -4/13

Given:

Length of a carton = [tex]2\dfrac{2}{3}[/tex] feet

Width of a carton = [tex]1\dfrac{1}{8}[/tex] feet

Height of a carton = [tex]1\dfrac{1}{5}[/tex] feet

To find:

The volume of the carton.

Solution:

We know that, volume of the carton is

[tex]V=length\times width \times height[/tex]

Putting the values, we get

[tex]V=2\dfrac{2}{3}\times 1\dfrac{1}{8} \times 1\dfrac{1}{5}[/tex]

[tex]V=\dfrac{(2\times 3)+2}{3}\times \dfrac{(1\times 8)+1}{8} \times \dfrac{(1\times 5)+1}{5}[/tex]

[tex]V=\dfrac{8}{3}\times \dfrac{9}{8} \times \dfrac{6}{5}[/tex]

Taking LCM, we get

[tex]V=\dfrac{18}{5}[/tex]

[tex]V=3\dfrac{3}{5}[/tex]

So, the volume is [tex]3\dfrac{3}{5}[/tex] cubic feet.

Therefore, the correct option is A.

Answer:

a = (b + c)/(bx - 1)

Step-by-step explanation:

Given

x= (a+b+c)/(ab)

Solving for a

x = (a + b+ c)/(ab)

abx = a + b+ c

abx - a = b + c

a(bx - 1) = b + c

a = (b + c)/(bx - 1)
