suppose that 23 inches of wire cost 69 cents at the same rate, how much in cents will 45 inches of wire cost

(-4z + 3y - 5) + (y - 5x + 6) =

-4z + 3y - 5 + y - 5x + 6 =

-4z + 4y - 5x + 1

Step-by-step explanation:

768775567iooi888776432

-4y + 12 = 36

-4y = 24

y = - 6

Answer:

y = -6

Step-by-step explanation:

To solve for y, you must isolate the variable by first dividing both sides by -4:

-4 (y-3) = 36

÷-4

y-3 = -9

Next, add 3 to both sides and you will get your final answer:

y-3 = -9

+3

y = -6

To check your answer, you can plug in -6 for y to ensure that the overall result is 36:

-4(-6-3) = -4(-9) = 36

36 = 36

Answer:

12x^227xy^2 - 20xy4y^3

Step-by-step explanation:

(-3x5y) (-4x9y^2)

first : -3x (-4x9y^2) = 12x^227xy^2

second: 5y(-4x9y^2) = -20xy45y^3

then we add them (12x^227xy^2) + ( -20xy45y^3)

= 12x^227xy^2 - 20xy45y^3

Answer:

The dimensions are:

Length = 5m and Width = 4m

Or

Length = 4m and Width = 5m

Step-by-step explanation:

A rectangular dining room has an area of 20 square meters. It's perimeter is 18 meters. What are the dimensions of the dining room?

Area of a rectangle = Length × Width

= LW = 20 m²

Perimeter of a rectangle =

2L + 2W = 18 m

Hence:

LW = 20...... Equation 1

L = 20/W

2L + 2W = 18 ...... Equation 2

We substitute

20/W for L in Equation 2

2(20/W) + 2W = 18

40/W + 2W = 18

Multiply through by W

40 + 2W² = 18W

2W² - 18W + 40 = 0

2W² - 10W - 8W + 40 = 0

(2W - 8 )(W - 5) = 0

2W - 8 = 0

2W = 8 , W = 8/2 = 4m

W - 5 = 0

W = 5m

W = 4m or 5 m

Solving for L

When W = 5 m

L = 20/W

L = 20/5

L = 4m

When W = 4m

L = 20/W

L = 20/4

L = 5m

Therefore, the dimensions are:

Length = 5m and Width = 4m

Or

Length = 4m and Width = 5m

Answer:

B

Step-by-step explanation:

Reflect x-axis means (x,y) becomes (x, -y)

Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x

Up 4 units means f(x) = x becomes f(x)= x + 4

So lets put that together

[tex]f(x) = \sqrt{x}[/tex]

[tex]f(x) = -\sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x}[/tex]

[tex]f(x) = -\frac{1}{3} \sqrt{x} + 4[/tex]

Answer:

because WXYZ is a rhombus

=> WX // YZ

=> ZWX + WZY = 180⁰

=> WZY = 180⁰ - ZWX = 180⁰ - 77⁰ = 103⁰

Answer:

$80

Step-by-step explanation:

Substitute x for 40 in both equations. Let's start with 50 + 12x. The equation becomes 50 + 12(40). First, multiply 12 by 40 to get 480. Now add 480 to 50 to get a total of $530 in printing fees for Company A.

Now, let's move on to 10 + 15x. That becomes 10 + 15(40). First, multiply 15 by 40 to get 600. Then add 10 to 600 to get $610 in printing fees for Company B.

Now that we know the total costs, let's subtract them to get our difference. Simply subtract 530 from 610 to get our final answer: an $80 difference in printing fee costs between the companies.

B. is the answer i did the test and it was right

Answer:

e = -6

f = -2

Step-by-step explanation:

I used the elimination method and multiplied the second equation by 5 to get:

  -5e + 10f = 10.  Added this to:

+  5e + 3f = -36

13f = -26

f = -2

now find e:  -e - 4 = 2

-e = 6

e = -6

Answer:

The equation required to find the volume of concrete is:

L X W X H.

Step-by-step explanation:

L = Lenght

W = Width

H = Height

To calculate the required volume for concrete, you'd need to multiply the measures of all the dimensions together such as the lenght and the breath (which gives you the Area) and the thickness or height of the staircase.

If the calculation is being expressed in Feet, the answer will also be expressed as Volume of concrete in Cubic feet.

Answer:

-5-85

Step-by-step explanation:

The temperature in Hawaii on Thursday was 85°F.

The temperature in Colorado on Thursday was - 5°F.

The difference in temperature is given by :

[tex]\Delta T=-5-85[/tex]

So, the correct option is (b) "-5-85".

Answer:

x = -56/5, -11 1/5, or -11.2

Step-by-step explanation:

5/7x - 14 = -22

5x -98 = -154

5x = -154 + 98

5x = -56

x = -56/5, -11 1/5, or -11.2

Answer:

x= -11.2

Step-by-step explanation:

5/7x-14=-22

      +14 +14        Add 14 on both sides

  5/7x = -8        

(7/5)*5/7x = -8*(7/5)     Multiply by the reciprocal on both sides to leave x alone

  x= -11.2      Answer
