n-3. Evaluate the algebraic expression when n=5
A. 2
B. 8
C. 5
D. 5/3

Answer:

5 feet (60 inches) proportional to 2 inches is a 30:1 relationship.

15 feet (180 inches) in real life should equal 6 inches on the diagram.

180 divided by 30 = 6

Step-by-step explanation:

Answer:

6 inches

Step-by-step explanation:

Step 1: Add 3x to both sides to get 4 = 3x - 1

Step 2: Add 1 to both sides to get 5 = 3x

Step 3: Divide by 3 on both sides to get 5/3 = x

Answer:

x = [tex]\frac{5}{3}[/tex]  or [tex]1 \frac{2}{3}[/tex]

Step-by-step explanation:

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

~

Step 1:

Subtract 4 from both sides of the equation:

4 (-4) - 3x = -1 (-4)

-3x = -1 - 4

-3x = - 5

Step 2:

Divide -3 from both sides of the equation:

(-3x)/-3 = (-5)/-3

x = -5/-3

x = 5/3

x = 1 2/3

Answer: -2

Step-by-step explanation:

Look for 1 on the x-axis and put your finger on it.

Move your finger down until it hits a point on the line.

Look to the left to see which number on y-axis corresponds with the point.

The number is the answer.

(1, -2)

Answer:

  c.  x = 1

Step-by-step explanation:

c. The Pythagorean theorem applies. The square of the hypotenuse is the sum of the squares of the other two sides.

  2² = x² +(√3)²

  4 = x² +3

  1 = x² . . . . . . subtract 3

  1 = x . . . . . . . take the square root

Answer:

-49%

Step-by-step explanation:

i know this one by doing a long math formula

Answer:

49.0%

Step-by-step explanation:

take the 2 numbers and find the difference

51 - 26 = 25

take the difference and divide it by the orginal number

25÷51 = 0.49019607843

then times that number by 100

(25÷51) × 100 = 49.0196078431

so the number was decreased by 49.0 %

Answer:

[tex]y = -\frac{1}{5}x + 5[/tex]

Step-by-step explanation:

Given

[tex]5\ minutes = 4\ miles[/tex]

[tex]15\ minutes = 2\ miles[/tex]

Required

Determine the equation

y represents distance

x represents time

So, the given parameters can be modeled (x,y) as:

[tex](x_1,y_1) = (5,4)[/tex]

[tex](x_2,y_2) = (15,2)[/tex]

First, we need to determine the slope of the function.

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2 - 4}{15 - 5}[/tex]

[tex]m = \frac{-2}{10}[/tex]

[tex]m = -\frac{1}{5}[/tex]

The equation can be determined using:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = -\frac{1}{5}[/tex]

[tex](x_1,y_1) = (5,4)[/tex]

[tex]y - y_1 = m(x - x_1)[/tex]

becomes

[tex]y - 4 = \frac{-1}{5}(x - 5)[/tex]

Open bracket

[tex]y - 4 = -\frac{1}{5}x + 1[/tex]

Solve for y

[tex]y = -\frac{1}{5}x + 1 + 4[/tex]

[tex]y = -\frac{1}{5}x + 5[/tex]

Answer:

SAS

Step-by-step explanation:

SAS stands for Side Angle Side. Because the two triangles have a side, angle, and side in common, SAS is the correct answer.

Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.

Moving left or down causes the coordinates to be going negative.

Moving right or up causes the coordinates to be positive.

Original point (10, 1).

Down 1 unit:

(10, 1 - 1) = (10, 0)

Left 7 units:

(10 - 7, 0) = (3, 0)

You end at (3, 0)

Answer: $21.52

Step-by-step explanation: 2.69 times 8 = $21.52

Answer:

we have the width is 8 cm and the diagonal line is 17 cm so to get the length you're going to use Pythagoras theorem so 8 centimetres will be represented by a 17cm will be represented by c then length will be represented by b so b squared is equals to c squared minus a squared say 17 squared - 8 squared 17 squared is 289 while 8 squared is 64 the result will be 225 so b squared is equals to 225 to get b we will get the square root so b is equals to 15 so our length is 15 the area is equals to length x width so 15 * 8 you get 120 square centimetres

120 square centimeters is the area of rectangle FGHK.

Area of a rectangle (A) is the product of its length (l) and width (w).

here, we have,

from the given figure,

we have the width is 8 cm and the diagonal line is 17 cm

so to get the length you're going to use Pythagoras theorem

so 8 centimeters will be represented by a

17cm will be represented by c

then length will be represented by b

so b squared is equals to c squared minus a squared

say 17 squared - 8 squared

17 squared is 289 while 8 squared is 64

the result will be 225

so b squared is equals to 225

to get b we will get the square root

so b is equals to 15

so our length is 15

the area is equals to length x width

so 15 * 8

you get 120 square centimeters.

hence, 120 square centimeters is the area of rectangle FGHK.
