Option (D)

Step-by-step explanation:

Given expression is,

x³ × 3 ÷ [tex]\frac{2}{9}[/tex] + 9x - (7 - 6x)

By substituting x = [tex]\frac{2}{3}[/tex],

[tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-6(\frac{2}{3})][/tex]

By using rule PEMDAS,

P - Parenthesis

E - Exponent

M - Multiplication

D - Division

A - Addition

S - Subtraction

[tex]=(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-4][/tex]

= [tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-3[/tex]

= [tex]\frac{8}{27}\times 3 \div \frac{2}{9}+6-3[/tex]

= [tex]\frac{8}{9}\div \frac{2}{9}+6-3[/tex]

= [tex]\frac{8}{9}\times \frac{9}{2}+6-3[/tex]

= 4 + 6 - 3

= 7

Answer:

C. -1x + (2)

Step-by-step explanation:

(2x + 6) - (3x + 4)

= 2x + 6 -3x - 4

= 2x - 3x + 6 - 4

= -1x +2

Answer:

C

Step-by-step explanation:

Expand the brackets = 2x + 6 - 3x - 4

Take 3x from 2x to get -1x

The equation is now -1x + 6 - 4

Take 4 from 6 to get 2

The equation is now -1x + 2, which is equal to option C

Answer:

09

Step-by-step explanation:

Step-by-step explanation:

Two functions are defined by these equations:

f(x) = 5.1 + 0.8x

g(x) = 3.4 + 1.2x

Put x = 3.9 in both f(x) and g(x).

f(x) = 5.1 + 0.8(3.9)

= 8.22

g(x) = 3.4 + 1.2(3.9)

= 8.08

So, f(x) is greater than g(x).

f(x)-g(x) = 8.22 - 8.08

= 0.14

So, f(x) is 0.14 units more than g(x).

The retail value of the total sales was $311.48

Step-by-step explanation:

14 1/4 dozen cloths were sold

This means that the total number of cloths sold was:

[tex]14*12 + 12*\frac{1}{4} = 168 + 3 = 171[/tex]

Each for $1.88

So the retail value of total sales was.

$1.88*171 = $311.48

The retail value of the total sales was $311.48

Answer:

B. x = 8√3 ≈ 13.86; y = 8

Step-by-step explanation:

✔️Find x using trigonometric ratio:

Reference angle = 60°

opposite = x

Hypotenuse = 16

Thus:

Sin(60) = x/16

16*sin(60) = x

16*√3/2 = x

8√2 = x

x = 8√3 ≈ 13.86

✔️Find y using Pythagorean Theorem:

y² = 16² - (8√3)²

y² = 256 - 192 = 64

y = √64

y = 8

Answer:

Since an equilateral triangle has all three side equal then one of its side is 38mm

The length of one of the sides of the triangle is 38 mm.

The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.

Given that all of the sides of an equilateral triangle are equal in length, we may calculate the length of a side by dividing the perimeter by the triangle's total number of sides, which is 3.

As a result, the equilateral triangle's one side has the following length:

114 mm / 3 = 38 mm

Therefore, the equilateral triangle's sides are each 38 mm long.

Answer:

Saints team scores points = 17

Browns team scores point = 30

Step-by-step explanation:

Let Saints team scores points = x

      Browns team scores point = y

As given,

The Browns scored 13 more points than the Saints.

⇒ y = x + 13

Now, given

The total of  their scores was 47.

⇒ x + y = 47

⇒x + x + 13 = 47

⇒ 2x = 47 - 13

⇒2x = 34

⇒x= [tex]\frac{34}{2}[/tex] = 17

∴ we get

Saints team scores points = x = 17

Browns team scores point = y = x + 13 = 17 + 13 = 30

Answer:

30 , 17

Step-by-step explanation:

browns  have x + 13

saints have y

x+13 + x+y = 47

2x = 34

x=17

17 + y = 47

y=30
