Answer:

Length + Width = 8 ft

Step-by-step explanation:

"The perimeter of a rectangle is 16 ft."

A perimeter is the sum of four sides of a rectangle.

OR...

Perimeter = Side 1 + Side 2 + Side 3 + Side 4

A rectangle has "matching sides", so...

Length: Side 1 = Side 3

Width: Side 2 = Side 4

Therefore we can just say that:

Perimeter = (Length * 2) + (Width * 2)

We can pull the 2 out:

Perimeter = 2 * (Length + Width)

Since Perimeter = 18

16 = 2 * (Length + Width)

Divide both sides by 2

8 = Length + Width

Length + Width = 8 ft

Answer:

"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.

Answer:

2/6 is read as "2 out of 6" or "2 in 6"

Step-by-step explanation:

Since there are 6 sides on a dice you have a 2 in 6 chance of rolling either a 4 or a 6. The probability of rolling one over the other would be 1/6

Answer:

C. {-9,-3}

Step-by-step explanation:

[tex]|k+6|=3[/tex] gives [tex]k+6=3[/tex] if [tex]k + 6 \geq 0[/tex]. This gives [tex]k=-3[/tex], which is valid.

It can also give [tex]-(k+6) = 3[/tex] if [tex]k + 6 < 0[/tex]. This gives [tex]k=-9[/tex], which is valid.

Hence the solutions are [tex]k=-9 \vee k=-3[/tex].

       y = -1

     2x - 3 = 1

    2x = 4

    x = 2

   (2, -1)

2a.  x + 2y = 4

       2x - 5y = -1

     -2x - 4y = -8

      2x -  5y = -1

    -9y = -9

      y= 1

2x - 5 = -1

 2x = 4

  x = 2

(2, 1)

2b. 4x + 2y = 4

       x - 2y = -5

       5x = -1

        x= -1/5

    -1/5 - 2y = -5

    -2y = -4 4/5

      y= 12/5

(-1/5, 12/5)

3. 5x + 3y = 85

  11x + 5y = 163

25x + 15y = 425

-33x - 15y = -489

 -8x = -64

x = 8 regular

5(8) + 3y = 85

40 + 3y = 85

3y = 45

y = 15 mini bouquets    

(8 regular, 15 mini bouquets)

4a. 6x + 12y = -6

     18x - 12y = - 162

24x = -168

x = -7

3(-7) - 2y = -27

-21 - 2y = -27

-2y = -6

y= 3

(-7, 3)

4b. 3(6 -y) - 2y = 38

     18 - 3y - 2y = 38

     18 - 5y = 38

    -5y = 20

    y = -4

x = 6 + 4

x = 10

(10, -4)

Answer: (-4,-2)

(2y)-7y=10

-5y=10

y=-2

X=2(-2)

X=-4

The length (JL) of the right-angle triangle will be 1.732 units.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

In the right triangle shown, angle ∠K = 60° and KL is 2. Then the measure of the length JL will be given by the sine the angle ∠K. Then the equation is given as,

JL / KL = sin ∠K

h / 2 = sin 60°

h / 2 = √3 / 2

h = √3

h = 1.732 units

The length (JL) of the right-angle triangle will be 1.732 units.

Step-by-step explanation:

Linear pairs are supplementary. Vertical angles are congruent. An angle is the sum of its parts.

(a) C: supplementary to 138°, 180° -138° = 42°

(b) O: congruent to 138°

(c) R: supplementary to 32°, 180°-32° = 148°

(d) H: congruent to 32°

(e) S: complementary to 28°, 90° -28° = 62°

(f) O: supplementary to 122°, 180° -122° = 58°

(g) W: congruent to 122°

(h) C: supplementary to 28°, 180° -28° = 152°

(i) I: supplementary to 60°, 180° -60° = 120°

(∠TSW) E: supplementary to a right angle: 180° -90° = 90°

(∠TSU) O: half the complement of 20°, (90° -20°)/2 = 35°

Answer:

the missing length is 14 feet.

Step-by-step explanation:

a = L × W

168ft² = 12 × W     - divide both sides of the equation by 12

                             - 168 ÷ 12 = 14

168ft² = 12 × 14

Answer:

a) (+) × (?) = (+)

(?) = (+)

b) (-) × (+) = ?

? = (-)

c) (?) × (-) = ?

? is undefined

Step-by-step explanation:

a) (+) × (?) = (+)

From the given equation in the question, by dividing both side of the equation by (+), we have;

((+) × (?))/(+) = (+)/(+)

(?) = (+)/(+) = (+)

Therefore, we have;

(+) × (+) = (+)

(?) = (+)

b) (-) × (+) = ?

From the given equation in the question we apply the operation rules as follows;

(-) × (-) = (+)

(-) × (+) = (-)

Therefore;

(-) × (+) = ? = (-)

? = (-)

c) (?) × (-) = ?

From the rules of multiplication, we have;

(-) × (-) = (+)

(+) × (-) = (-)

Therefore, when (?) = (-), ? = +, from which we have;

(?) ≠ ?, which is an error

Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign

Therefore, the equation, (?) × (-) = ?, is undefined.
