Answer:

Step-by-step explanation:

2(k-5)+3k=k+6k=

We move all terms to the left:

2(k-5)+3k-(k+6k)=0

We add all the numbers together, and all the variables

2(k-5)+3k-(+7k)=0

We add all the numbers together, and all the variables

3k+2(k-5)-(+7k)=0

We multiply parentheses

3k+2k-(+7k)-10=0

We get rid of parentheses

3k+2k-7k-10=0

We add all the numbers together, and all the variables

-2k-10=0

We move all terms containing k to the left, all other terms to the right

-2k=10

k=10/-2

k=-5

Answer:

213,645.6cm³

Step-by-step explanation:

Area of a cylinder is expressed as;

V = πr²h

r is the radius = 2cm

h is the height = 70cm

Get the volume of one rod;

V = πr²h

V = (3.14)(2)²(70)

V = (3.14)(4)(70)

V = 879.2cm³

one steel = 879.2cm³

243 rods = x

Cross multiply;

x = 879.2 * 243

x = 213,645.6

The company will need 213,645.6cm³ volume of steel to make 243 rods

d-13=5 is actually suppose to be solved liek this:

d - 13 = 5

   +13   +13

The absoulte value of 13 is 13, it is negative so you have to add 13 to get to 0 so it can be cancelled out.

175-20%= 35 off

175-35=140

140*8% tax= 11.20 tax

140+11.20= 151.20

151.20*18% tip= 27.216

151.20+27.22=178.42 total

Answer:

$1875

Step-by-step explanation:

Money available with Dubois family = $5000

Money to be spent on gasoline and motel room = [tex]\frac{1}{4}[/tex] of the total amount

Therefore,

Money to be spent on gasoline and motel room = [tex]\frac{1}{4} \times 5000 = \$1250[/tex]

Remaining amount of money = Total amount - Money spent on gasoline and motel room  

Remaining amount of money = $5000 - $1250 = $3750

As per question statement:

Half of the remaining money is to be spent on meals.

i.e. Money to be spent on meals = [tex]\frac{1}{2}\times \$3750 = \bold{\$1875}[/tex]

Therefore, the answer is:

$1875

Step-by-step explanation:

Answer:

w= 2

Step-by-step explanation:

3-2w+4w=7. We move all terms to the left: 3-2w+4w-(7)=0,  Then we add all the numbers together, and all the variables: 2w-4=0. After, we move all terms containing w to the left, all other terms to the right: 2w=4, w=4/2

w=2

Answer:

$0.05 per ounce

Step-by-step explanation:

Mrs. O'Brien purchases 112 ounces of laundry detergent for $13.44.

Units price = Total cost of the detergent / number of ounces

= $13.44 / 112 ounces

= $0.12 per ounce

Mr. O'Brien purchases a 280 ounce container of laundry detergent for $19.60.

Units price =Total cost of the detergent / number of ounces

= $19.60 / 280 ounces

= $0.07 per ounce

Difference in the unit price per ounce for the laundry detergents Mr. And Mrs. O'Brien purchase = $0.12 per ounce - $0.07 per ounce

= $0.05 per ounce

Answer:

Remainder = zero

Answer = (4x^3)  +(5x^2) -4x +3  or 4x³ +5x²-4x+3

Step-by-step explanation:

        (4x^3)  +(5x^2) -4x +3        

x-4√4x^4-11x^3-24x^2+19x-12               We multiply (x-4) by  4x³      

        4x^4-16x^3

       -          +          

                5x^3-24x^2+19x-12

                 5x^3-20x^2                          We multiply (x-4) by  +5x²    

                -          +        

                        -4x^2+19x-12

                         -4x^2+16x                          We multiply (x-4) by - 4x

                         +         -            

                                    3x-12

                                     3x-12                      We multiply (x-4) by +3

                                  -       +          

                                 zero remainder

We keep multiplying the factor  (x-4)  by different terms to get the first term desired in each step . Then we subtract by changing the signs and get the remainder.

The answer is the expression obtained at the top.

4x^4-11x^3-24x^2+19x-124 /x-4 = 4x³ +5x²-4x+3

If a rectangle has vertices (0,0), (2k,0), and (0,k)  the fourth vertex will be (4,8).

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is given that the rectangle has vertices (0,0), (2k,0), and (0,k).

A(0,0)
B(2k,0)

C(0,k)

D(x,y)

Since the opposite of the rectangle is the same it will be opposite to one of the coordinates shown in the graph.

To uniquely identify points on a plane, use ordered pairs and the rectangular coordinate system (x,y). Pairs that are ordered show position in relation to the origin.

The x-coordinate shows the left and right sides of the origin. Y-coordinate positions are above or below the origin.

Thus, if a rectangle has vertices (0,0), (2k,0), and (0,k)  the fourth vertex will be (4,8).

Definition: Standard deviation is the measure of dispersion of a set of data from its mean. It measures the absolute variability of a distribution; the higher the dispersion or variability, the greater is the standard deviation and greater will be the magnitude of the deviation of the value from their mean.
