Step-by-step explanation:

See the attached image.

The Polynomial form of F(x) / d(x)  is  (x - 6) + 7 / (x - 6).

It is the basic arithmetic operation, in which you are separating the number into some parts.

Given:

F(x) = x² - 12x +43

d(x) = x - 6

Then,

F(x) / d(x) =  x² - 12x +43 / x - 6

Factorize the numerator,

F(x) / d(x) = [(x - 6) (x - 6) + 7] / (x - 6)

F(x) / d(x) = (x - 6) (x - 6) / (x - 6) + 7 / (x - 6)

F(x) / d(x) = (x - 6) + 7 / (x - 6),

Therefore, the Polynomial form of F(x) / d(x)  is  (x - 6) + 7 / (x - 6).

Answer:

x = 3/4

Step-by-step explanation:

Answer:

x = 3/4

Step-by-step explanation:

Find the LCD of the fractions.  Multiplying the denominators 3 and 4 together, we get LCD = 12.  

Rewriting the mixed numbers, we get

3 2/3 = 3 8/12 and 3 1/4 = 3 3/12

So the original equation becomes

(3 8/12)x + 3 3/12 = 6

We must now combine like terms:  subtract 3 3/12 from both sides of this equation, obtaining:

(3 8/12)x = 6 - 3 3/12, or

(3 8/12)x = 2 9/12.  Converting the mixed numbers into improper fractions, we get:

(44/12)x = 33/12.  Multiplying both sides by 12 yields 44x = 33

and so x = 33/44 = 3/4

x = 3/4

Alternatively, convert the original mixed numbers into improper fractions right away.  Then the original   3 2/3 x+3 1/4=6

becomes (11/3)x + 13/4 = 72/12, or

                 (44/12)x + 39/12 = 72/12

Multiplying all three terms by 12 yields:

44x + 39 = 72, which simplifies to 44x = 33, or x = 3/4

Speed  = 93km /h  and  72km/h

Answer: The taxi went a distance of 554.7km

Step-by-step explanation:

Speed  = Distance / Time

Distance covered in the first trip = Speed x Time

Time = 1 hour 54 min =1+0.9 hours  =1.9hours

=93km / h x 1.9 hours =176.7km

Distance covered in the second  trip = Speed x Time

Time = 5 hours 15min = 5+0.25hours  =5.25hours

=72km / h x 5.25hours =378 km

Total distance =176.7km+378 km

=554.7km

Answer:

To find a a fraction of a whole number, you multiply the numerator of the fraction by the given number and then divide the product by the denominator of the fraction

Solved example for finding a fraction of a whole number:

1)

Find 1/3 of 21.

To find 1/3 of 21, we multiply the numerator 1 by the given whole number 21 and then divide the product 21 by the denominator 3.

1/3 × 21 = 1 × 21/3 = 21/3 = 7

So, 1/3 of 21 = 7.

1/3 of 21 is 7

Answer:

For finding a fraction of a whole number, we multiply the numerator of the fraction by the given number and then divide the product by the denominator of the fraction.

Find 2/5 of 15.

To find 2/5 of 15, we multiply the numerator 2 by the given whole number 15 and then divide the product 30 by the denominator 5.

2/5 × 15 = 2 × 15/5 = 30/5 = 6

So, 2/5 of 15 = 6.

Find 3/8 of 48.

To find 3/8 of 48, we multiply the numerator 3 by the given whole number 48 and then divide the product 144 by the denominator 8.

Step-by-step explanation:

A root is equivalent to a fractional power. A square root is a 1/2 power. A cube root is a 1/3 power. The index of the root is the denominator of the fraction.

Of course the usual rules of exponents apply in evaluating an expression.

  (a^b)^c = a^(bc)

Your expression can be simplified as follows.

  [tex]\displaystyle\sqrt[3]{1000^2}=(1000^2)^{\frac{1}{3}}=1000^{\frac{2}{3}}=(10^3)^{\frac{2}{3}}=10^2=\boxed{100}[/tex]

It can also be simplified another way:

  [tex]\displaystyle\sqrt[3]{1000^2}=\sqrt[3]{(10^3)^2}=\sqrt[3]{(10^2)^3}=10^2=100[/tex]

Answer:

80 + 15x ≤ 300

Step-by-step explanation:

max amount = $300

already spent = $80

$300 - 80 = $220

shirts = $15 each

80 + 15x ≤ 300

$80 that is already spent + $15x ≤ $300 maximum

x = number of shirts

Answer:

angle x = 28 degrees

Step-by-step explanation:

Because of vertical angles, angle IAK and angle BAC are equal, and angle GCJ and angle ACB are also equal due to vertical angles

Since KL is perpendicular to FG, angle ABC is 90 degrees

ABC is a right triangle and acute angles in a right triangle are equal to 90 degrees

This means that angle BAC + angle ACB = 90 degrees

angle BAC = 62 degrees and angle ACB = x degrees

62 + x = 90

x = 28 degrees
