Answer:

(4, 6 )

Step-by-step explanation:

Given the 2 equations

3x + 4y = 36 → (1)

y = - [tex]\frac{1}{2}[/tex] x + 8 → (2)

Substitute y = - [tex]\frac{1}{2}[/tex] x + 8 into (2)

3x + 4(- [tex]\frac{1}{2}[/tex] x + 8) = 36 ← distribute and simplify left side

3x - 2x + 32 = 36

x + 32 = 36 ( subtract 32 from both sides )

x = 4

Substitute x = 4 into (2) for corresponding value of y

y = - [tex]\frac{1}{2}[/tex] × 4 + 8 = - 2 + 8 = 6

solution is (4, 6 )

Step-by-step explanation:

1. 3n+4n=28

         7n=28

           n=4

2. 2x+7-9=10

           2x=10+2

            2x=12

               x=6

3. 3(a+2)=-5

    3a+6=-5

         3a=-11

           a= -11/3

4. 2(3n-1)=19

      6n-2=19

          6n=21

            n=7/2

5. 3x-5-x+1=10

            2x=14

               x=7

6. -3-5=5-2a+7

      2a=20

        a=10

7. -5(n-2)= -15

        n-2=3

           n=5

8. Let the cost of each fan be y.

    6y+3y=1188

         9y=132

∴ The cost of each fan is $132.

Answer:

y = 4

Step-by-step explanation:

1. Find the slope

slope = rise over run or change in y divided by change in x

The slope of (2,4) and (6,4) is

(4 - 4)/(6 - 2) = 0/4 = 0

the slope is 0

2. Use point-slope form: y - y₁ = m(x - x₁)

(2, 4) -> x = 2 y = 4

m -> (slope) = 0

y - 4 = 0(x - 2)

y - 4 = 0

y = 4

Answer:

Step-by-step explanation:

In parallelogram opposite angles are equal

6x = 66      {Divide both sides by 6}

x = 66/6

x = 11

20y - 46 = 13y + 10     {Add 46 to both sides}

20y - 46 + 46 = 13y + 10 + 46

             20y   = 13y + 56     {Subtract 13y from both sides}

   20y - 13y    = 13y-13y + 56

              7y    =  56    {Divide both sides by 7}

                y =  56/7

y = 8

1/2 + 3/8 = 4+3/8 = 7/8

Answer:

7 / 8

Step-by-step explanation:

In order to add fractions, the denominators must be the same.

1 / 2 + 3 / 8

Find the least common denominator by prime factorization.

2:2

8:2, 2, 2

To determine the least common denominator (LCD), multiply the common factor 2 times the other factors in blue.

LCD = 2 × 2 × 2 = 8

Multiply  1 / 2 times 4 / 4 so that it will have a denominator of 8.

1 / 2 × 4 / 4 + 3 / 8

= 4 / 8 + 3 / 8

= 7 / 8

Answer:

x = 2

z = 85°

Step-by-step explanation:

95° + z = 180°

z = 180 - 95

z = 85°

z + (11x + 73) = 180°

85 + (11x + 73) = 180°

11x + 85 + 73 = 180°

11x + 158 = 180°

11x = 180 - 158

11x = 22

x = 22/11

x = 2

Answer:

D. 3/2

Step-by-step explanation:

The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

Answer:

12.5 units^2

Step-by-step explanation:

The shape is a trapezoid

The area of a trapezoid is given by

A = 1/2 ( b1+b2)h  where b1 and b2 are the lengths of the bases and h is the height

A = 1/2 ( 2.5+ 7.5) 2.5

A = 1/2 ( 10)2.5

A = 12.5 units^2

Step-by-step explanation:

Answer:

see in the pic, we have: E(-5; -3), F(-3; -6), A(-5; -8), B(1,-8), C(3; -5), D(1;0)

=> AB = 6

[tex]bc = \sqrt{(3 - 1) {}^{2} + ( - 5 + 8) {}^{2} } = \sqrt{13} \\ \\ \\ cd = \sqrt{(1 - 3) {}^{2} + ( - 5) {}^{2} } = \sqrt{29} \\ \\ \\ [/tex]

[tex]de = \sqrt{( - 5 - 1) {}^{2} + ( - 3) {}^{2} } = 3 \sqrt{5} [/tex]

[tex]ef = \sqrt{( - 3 + 5) {}^{2} + ( - 6 + 3) {}^{2} } = \sqrt{13} [/tex]

[tex]fa = \sqrt{( - 5 + 3) {}^{2} + ( - 8 + 6) {}^{2} } = 2 \sqrt{2} [/tex]

the perimeter of the shape = AB + BC + CD + DE + EF + FA

[tex] = 6 + \sqrt{13} + \sqrt{29} +3 \sqrt{5} + \sqrt{13} + 2 \sqrt{2} [/tex]

[tex] = 28.13[/tex]

Answer:3329.95

Step-by-step explanation:

The value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.

Given that, a quantity with an initial value of 990 grows exponentially at a rate such that the quantity doubles every 4 years.

Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).

We know that, S.I=(P×T×R)/100

Amount after 4 years is 1980

So, 990= (990×4×R)/100

⇒ 39.6R=990

⇒ R=990/39.6

⇒ R=25%

Amount = [tex]a(1+r)^t[/tex]

= [tex]990(1+0.25)^{0.7}[/tex]

= 1157.37

Therefore, the value of the quantity after 0.7 decades, to the nearest hundredth is 1157.37.

Answer:

(3x + 4y - 3z)(3x + 4y + 3z)

Step-by-step explanation:

(3x + 4y)² - (3z)² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Here a = 3x + 4y and b = 3z, then

(3x + 4y)² - (3z)²

= (3x + 4y - 3z)(3x + 4y + 3z) ← in factored form

Answer:

El largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m

Step-by-step explanation:

Un rectángulo es un cuadrilátero con dos lados de igual longitud y dos lados de igual ancho que contiene cuatro ángulos rectos. Para encontrar el área de un rectángulo, debes multiplicar su longitud por su ancho. Es decir, el área del rectángulo es igual al largo por el ancho.

En este caso, sabes que el ancho es dos veces más pequeño que el largo. Entonces, siendo el largo x, el ancho tendrá un valor de x÷2.

Siendo el área del terreno rectangular 16,200 m², entonces

x*(x÷2)= 16,200 m²

Resolviendo:

x² ÷2= 16,200 m²

x²= 16,200*2 m²

x²= 32,400 m²

x= √32.400 m²

x= 180 m

Entonces, el largo tendrá un valor de 180 m y al ancho tendrá un valor de 90 m (180 m÷ 2)
