If 4^x - 4^x-1 = 24, then evaluate (2x)^x.Plzz help me solve this

Answer»

{4}^{x}  -  {4}^{x - 1}  = 24 \\  \\   {4}^{x}  -  {4}^{x} \times  {4}^{ - 1}  = 24 \\  \\  {4}^{x} (1 -  {4}^{ - 1}) = 24 \\  \\  {4}^{x}(1 -  \frac{1}{4} ) = 24 \\  \\  {4}^{x} ( \frac{3}{4} ) = 24 \\  \\  {4}^{x}  =  \frac{24}{ \frac{3}{4} }  \\  \\  {4}^{x}  =  \frac{96}{3}  \\  \\  {4}^{x}  = 32 \\  \\  { ({2}^{2} )}^{x}  =  {2}^{5}  \\  \\  {2}^{2x}  =  {2}^{5}  \\  \\ 2x = 5 \\ x = 2.5

Now,

{2x}^{x} \\  \\ {(2 \times 2.5)}^{2.5} \\   \\  {5}^{2.5}  \\  \\  {5}^{ \frac{25}{10} }  =  {5}^{ \frac{5}{2} }  =  {( {5}^{5} )}^{ \frac{1}{2} }  =  {3125}^{ \frac{1}{2} }  =  \sqrt{3125}  = 25 \sqrt{5}

X+2y =1.6, 2x+y=1.4 solve the problem using substitution method​

Answer»

Answer:

X + 2y = 1.6

2x + y = 1.4

multiply by 10 to the both equations

10x + 20Y = 16.........(1)

20x + 10y = 14...........(2)

so from (1)

x =( 16 - 20y )/10

put this value of x in EQUATION (2)

20(( 16 - 20y )/10)+ 10y = 14

320 - 400y + 100y = 140

-300y = 140 - 320

y = -180 / -300

= 60 / 100

= 60 x 10^(-2)

y = 0.6

put this value of y in equation (1)

10x + 20(0.6) = 16

10x + 12 = 16

x = (16 - 12)/10

x = 4 / 10

x = 4 x (10)^(-1)

x = 0.4

14.

Raman's monthly salary is rupees 96000. He spends 1/4 of his salary in food 1/5 on rent and 1/6 on the education of childrens . find (¡) How much does he spend on each part (¡¡) How much money is still left with him?​

Answer»

Answer:   Salary = 96000

Spent on FOOD = 1/4 of salary = 1/4 * 96000 = Rs. 24000

Spent on education = 1/6 of salary = 1/6 * 96000 = Rs. 16000

Spent on RENT = 1/5 of salary = 1/5 * 96000 = Rs. 19200

Total money spent = 24000 + 16000 + 19200 = Rs. Rs. 59,200

Therefore, money remaining = salary - spent = 96000 - 59200 = Rs. 37, 800

By selling an article for rs. 300, a trader made a profit of 25%. Now, if the trader gives a successive discount of 15% and 10% on the existing selling price, then how much profit/loss does he earn?​

Answer»

Answer:

10.5

Step-by-step explanation:

Given  

By selling an article for rs. 300, a trader made a profit of 25%. Now, if the trader GIVES a successive discount of 15% and 10% on the existing  selling price, then how MUCH profit/loss does he EARN?​

Let the cost of the article be x and profit is 25%

25/100 = 0.25 + 1(article) = 1.25

So original price of article will be

(1.25) = 300

 x = 300 /1.25 = Rs 240

Now he made a profit of 25% of 240 = Rs 60

So total will be 240 + 60 = Rs 300

First 15% of 300 = 15/100 x 300 = 45

300 – 45 = Rs 255

Again 10% of 255 will be 10/100 x 255 = 25.5

255 – 25.5 = Rs 229.5

From Rs 240, now he has only Rs 229.50. So 240 – 229.50 = Rs 10.5.

So it a loss of Rs 10.5

Add 3/ 2 and 5/ 3 using the number line​

Answer»

Answer:

Step-by-step explanation:

To add a positive number means that we move the point to the right of the number line.

Similarly, to add a negative number IMPLIES that we move the point to the left of the number line.

here is a diagram of a number with zero at the center, integers 1 to 7 on the right side, and integers -1 to -7 on the left side. there are NOTES under the number line that to add a positive number, you move some units to the right of the number line while to add a negative number means you move some units to the left of the number line.

1.twice a number when decreased by 9 gives 43.2.thrice a number when increased by 5 gives 38.3.four added to twice a number yields 26/5.4 a number when added to its half gives 72

Answer»

Step-by-step explanation:

1. Let the number be x.

Twice the number is EQUAL to 2x

Decreased by 9 is equal to 2x-9.

According to the QUESTION 2x-9 =43.

2x=9+43

2x=52

x=52÷2

x=26.

Therefore the number is 26.

2.Let the number be x

Thrice the number is equal to 3X

Increased by 5 is equal to 3x+5

According to the question 3x +5=38

3x =38-5

3x =33

x=33÷3

x=11

Therefore the number is 11

3.Let the number be x

Twice a number is equal to 2x

Four added to the number is equal to 2x +4

According to the question 2x+4=26/5

2x =26/5 - 4

2x = 26-20/5

2x =6/5

2x ×5=6

10x=6

x=6/10

x=3/5

Therefore the number is 3/5.

4.Let the number be x

Half the number is equal to x/2

According to the question x+x/2 =72

2x+x=72

3x = 72

x=72/3

x = 24

Therefore the number is 24
