21/4=12\7:x

21 se simplifică  cu  7 și o să ne dea 3

și 1

12 se simplifică cu 4 și o să ne dea

3 și 1

3\1=3\1:x

x=3x3

x=9

Answer:

x = 0.327

Step-by-step explanation:

[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] ÷ x

[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7}[/tex] × [tex]\frac{1}{x}[/tex]

[tex]\frac{21}{4}[/tex] = [tex]\frac{12}{7x}[/tex]

[tex]\frac{21}{4}[/tex] x 7x = 12

[tex]\frac{147x}{4}[/tex] = 12

147x = 12 x 4

x = 48 ÷ 147

x = 0.327

Answer:

The domain of f is all real numbers (since it is a polynomial), hence the value of g(x) is not restricted in any way.

Answer:

C. 42.57 and 42.58

Step-by-step explanation:

The best way is to go to a calculator and put in the numbers:

7√37 is 42.5793377121

So you simplify

42.5793377121

which is

42.58

Now you got your two numbers:

42.57 and 42.58

(If you rounded down you will result in 42.57)

So the answer is C. 42.57 and 42.58

Answer: x > 5.

Step-by-step explanation:

The information given in the question can be expressed in an equation as:

Let the cost of each book be x

Cost of mug + Cost of books > 24

9 + (3 × x) > 24

9 + 3x > 24

3x > 24 - 9

3x > 15

x > 5.

Therefore, each book cost more than $5.

Answer:

35

Step-by-step explanation:

Just add up all the sides

Answer:

Cost of one pack = h+8

Step-by-step explanation:

Given that:

Amount Azil have = RM (h²-64)

Packs of flour Azil wants to buy = h-8

To find the price of a pack of flour, we will divide the total amount by packs of flour.

Unit rate = [tex]\frac{h^2-64}{h-8}[/tex]

Unit rate = [tex]\frac{h^2-8h+8h-64}{h-8} = \frac{h(h-8)+8(h-8)}{h-8}[/tex]

Unit rate = [tex]\frac{(h-8)(h+8)}{(h-8)}[/tex]

Unit rate = h+8

Hence,

Cost of one pack = h+8

Answer:

Please check the explanation.

Step-by-step explanation:

Given

ABC ↔ RQP

It means

Please check the attached diagram.

Here,

Parts of ΔABC that correspond to

(i) PQ

From the diagram, it is clear that:

PQ corresponds to CB

(ii) ∠Q

∠Q corresponds to ∠B

(iii) RP

RP corresponds to AC

Given:

Nick, Jim and June share money in the ratio 5:5:3.

In total Nick and June received £88.

To find:

The amount received by Jim.

Solution:

Let Nick, Jim and June received 5x, 5x and 3x respectively.

In total Nick and June received £88.

[tex]5x+3x=88[/tex]

[tex]8x=88[/tex]

[tex]x=\dfrac{88}{8}[/tex]

[tex]x=11[/tex]

Now, the amount received by Jim is

[tex]\text{Jim get}=5x[/tex]

            [tex]=5(11)[/tex]

            [tex]=55[/tex]

Therefore, the amount received by Jim is £55.

Answer:

The measure of angle A is:

m ∠ A = 53.13°

Step-by-step explanation:

Given

The length AC = 3 cm

The length BC = 4 cm

To determine

m ∠ A = ?

Using the trigonometric ratio

tan A = opposite / adjacent

From the right-angled triangle, as shown, it is clear that:

Thus, substitute opposite = 4 and adjacent = 3

tan A = 4 / 3

A = arctan (4/3)

A = 53.13°

Therefore, the measure of angle A is:

m ∠ A = 53.13°

Answer:

24/1

Step-by-step explanation:

24/1. because when you dive you get 24. 24 in fraction form is 24/1.

Answer:

1.42 minutes

Step-by-step explanation:

There are 4 total swimmers, who all swam an equal part of the distance.

The overal time was 5.69 minutes, so the average time is

5.69 min ÷ 4 = 1.42 minutes, on average.

Answer:

(a) 16:9  (b) 7:9

Step-by-step explanation:

Answer:

degree of the polynomial should be 12

Step-by-step explanation:

The mistake he did was that he was supposed to consider the highest power

The power of the term in front should

not be used if the term does not have the highest power

As we can see. the term with the highest power is 12

So we can say that the degree is 12 and not 2

Answer:

Step-by-step explanation:

Combine like terms. Like terms have same variable with same power

2x² + x + 3 + 3x² + 2x + 1 = 2x² + 3x²   + x + 2x + 3 + 1

                                        = 5x² + 3x + 4

Answer:

y = 2

Step-by-step explanation:

2.54 + 0.38y = 5.22 - 0.96y

1.34y = 2.68

y = 2

Answer:

A. 1/12+5/12+5/12

Step-by-step explanation:

From the given options; let us calculate the fractions and see which one tallies with 11/12

a) [tex]\dfrac{1}{12}+ \dfrac{5}{12} + \dfrac{5}{12}[/tex]

The lowest common multiple (L.C.M) here is 12 because 12 goes in all the denominators.

So;

[tex]= \dfrac{1+5+5}{12}[/tex]

[tex]= \dfrac{11}{12}[/tex]

b)

[tex]\dfrac{5}{4}+\dfrac{3}{4}+\dfrac{3}{4}[/tex]

Here, the  lowest number that can be divisible by the denominators is 4

[tex]=\dfrac{5+3+3}{4}[/tex]

[tex]=\dfrac{11}{4}[/tex]

c)

[tex]\dfrac{5}{6}+\dfrac{6}{6}[/tex]

[tex]=\dfrac{5+6}{6}[/tex]

[tex]=\dfrac{11}{6}[/tex]

d)

[tex]\dfrac{10}{12}+\dfrac{2}{12}[/tex]

[tex]=\dfrac{10+2}{12}[/tex]

[tex]= \dfrac{12}{12}[/tex]

= 1

Thus, from the given options, the expression that has the sum of 11/12 is option A.

Answer:

n × scale factor = n prime

n × 0.75 = n′

In other words per the equation above, a Scale Factor of 0.75 is the factor that you would multiply with n to get n′.
