Answer:

There are 5 black counters in the bag.

Step-by-step explanation:

15 green counters in the bag

The proportion of green counters is given by:

[tex]p = 1 - (\frac{1}{3} + \frac{1}{6}) = 1 - (\frac{2}{6}+\frac{1}{6}) = 1 - \frac{3}{6} = 1 - \frac{1}{2} = \frac{2}{2} - \frac{1}{2} = \frac{1}{2}[/tex]

So, we have that, the total is x. So

[tex]\frac{x}{2} = 15[/tex]

[tex]x = 30[/tex]

There are 30 total counters.

How many black counters are in the bag ?

A sixth of the counters are black. So

[tex]\frac{1}{6} \times 30 = \frac{30}{6} = 5[/tex]

There are 5 black counters in the bag.

Answer:

The solution to the system of equations be:

(x, y) = (16, 2)

Step-by-step explanation:

Given the system of equations

2 + 2y = 6

2x - 3y = 26

Isolate y for 2+2y=6

2+2y=6

subtract 2 from both sides

2+2y-2 = 6-2

2y = 4

divide both sides by 2

2y/2 = 4/2

y = 2

now substitute y = 2 in 2x - 3y = 26

2x - 3y = 26

2x - 3(2) = 26

2x-6=26

add 6 to both sides

2x-6+6=26+6

2x = 32

divide both sides by 2

2x/2 = 32/2

x = 16

Therefore, the solution to the system of equations be:

(x, y) = (16, 2)

Answer:

a certain number that i do not know

Step-by-step explanation:

        a). It will take 16 hours to earn $144.

        b). It will take 24.67 hours to earn $222

        c). In a 40 hours week he will earn $360.

             In a 7 hours day he will earn $63.

          Proportionality law states,

          y ∝ x

          y = kx  [here, k = proportionality constant]

If Adam earns $36 in 4 hours,

36 = 4k

k = 9

Therefore, expression for total earnings will be,

y = 9x

a). For y = $144,

    144 = 9x

     x = 16 hours

b). For y = $222,

    222 = 9x

     x = 24.67 hours

c). For 40 hour week,

    y = 9(40) = $360

    Adam will earn $360 in a week by the rate $9 per hour.

    For 7 hour day,

    y = 9(7) = $63

    Adam will earn $63 in a day by the rate of $9 per hour.

            Therefore, a). It will take 16 hours to earn $144.

                               b). It will take 24.67 hours to earn $222.

                               c). In a 40 hours week he will earn $360.

                                    In a 7 hours day he will earn $63.

Given:

Width of a garden = 10 feet

Length of the garden = 14 feet

Area of the garden and the walkway together = 396 square feet.

To find:

The width of the walkway.

Solution:

A cement walkway is added around the outside of the garden.

Let x be the width of the walkway.

The width of the garden with walkway = 10+2x

The length of the garden with walkway = 14+2x

Area of a rectangle is

[tex]Area=length\times width[/tex]

Area of garden and the walkway together is

[tex]Area=(14+2x)\times (10+2x)[/tex]

[tex]396=140+28x+20x+4x^2[/tex]

[tex]396=140+48x+4x^2[/tex]

[tex]396=4(35+12x+x^2)[/tex]

Divide both sides by 4.

[tex]99=35+12x+x^2[/tex]

[tex]0=35-99+12x+x^2[/tex]

[tex]0=-64+12x+x^2[/tex]

Splitting the middle term, we get

[tex]x^2+16x-4x-64=0[/tex]

[tex]x(x+16)-4(x+16)=0[/tex]

[tex](x+16)(x-4)=0[/tex]

Using zero product property, we get

[tex](x+16)=0\text{ and }(x-4)=0[/tex]

[tex]x=-16\text{ and }x=4[/tex]

Width of walkway cannot be negative. So, x=4.

Therefore, the width of the walkways is 4 feet.

Answer:

Original price was $2163

Step-by-step explanation:

Let original price be x

23% of x = 497.42

23/100 × x = 497.42

23x/100=497.42/1

Cross multipy,

23x × 1 = 497.42 × 100

23x=49742

x=49742/23

x=2,163 approximately
