If 5x-5+4=34 then the value of x is

Answer»

Answer:

7

Step-by-step explanation:

We can apply the CONCEPT of LINEAR equations for this question

5X - 5 + 4 = 34

5x = 34 + 5 - 4 *when we take a number to the other side we should change the sign*

5x = 35

X = 35/5 *5 changes to division when we take to other side*

x = 7//

Answer:

1)5

2) 2

3)6

4)N2

Step-by-step explanation:

If x−1x=3x-1x=3, then value of x3−1x3x3-1x3 is यदि x−1x=3x-1x=3 है, तो x3−1x3x3-1x3 का मान है​

Answer»

if x-1x=3x-1x=3

1st TERM = x-1x= 0

2nd term = 3x-1x=2x

3rd term = 3x

and no one is EQUAL

It's a math question...need some help...Kindly solve if you are sure that the answer is correct...thank you​

Answer»

Step-by-step explanation:

Step-by-step explanation:

Easy if you look carefully at the diagram.

Since side length , a = 8 units

and area of equilateral triangle =\sqrt{3}a^2/4

we get area =16root(3)

Now if we join FC,

we get angle AFC= 90 + 60/2 = 120 ( this is a ncert theorem since it can be EASILY proven that AE bisects angle A and FC bisects angle C)

and since AFC is congruent triangle to AFB Then by CPCT angle AFC=AFB=120 as required

(again I am CONSIDERING that you have basic knowledge level of NCERT)

and finally since AE and BD are medians  they DIVIDE each other in ratio 2:1 and AE^2=8^2 - 4^2=48

hence AE=4root(3)

and AF= 2/3 of 4root(3) = 8/root(3) your answer

Hope this helps!

An industrial loom weaves 0.128 m of cloth every second. How many seconds will it take for the loom to weave 16m of cloth?

Answer»

Answer:

The answer is 125 SECONDS

Step-by-step explanation:

Step = if an industrial loom weaves 0.128 m of cloth in EVERY second(1)

And how MANY seconds it will take to weave 16  m of cloth

Let the number of seconds be y to weave 16 m of cloth

That is,

0.128(128/1000) = 1 second

16 = y

Now, follow cross multiplication

128/1000  X y = 16 X 1

16 X 1000/128 = y

1000/8 = y

125 seconds = y(The number of seconds to weave 16 m of cloth)

If 2x = 3+√7, find 4x2+1/x2​

Answer»

2x = 3+√7

=> x = (3+√7)/2

4x²+1/x²

= 4{(3+√7)/2}² + 1/{(3+√7)/2}²

= 4{(16+6√7)/4} + 1/{(16+6√7)/4}

= (16+6√7) + 4/(16+6√7)

= (512+192√7)/(16+6√7)

= {32(16+6√7)}/(16+6√7)

= 32 .

In a rectangle ABCD, it's diagonal AC=15cm and angle ACD = alpha. if cot alpha=3/2, find perimeter and area of the rectangle.​

Answer»

Answer:

The perimeter is 150/√13.

Step-by-step explanation:

LET's say if THETA is the angle between diagonal and the side of the rectangle then

AB/BC = cot θ

If cotθ = 3/2 then sinθ = 2/√13

Sin θ = BC/AC

2/√13 = BC / 15

BC = 30/ √ 13

Similarly COS θ  = 3/√13

cos θ  = AB/AC =AB/15

3/√ 15 =AB /15 so AB = 45/√13

So perimeter = 2(AB+ BC)

                      = 2(30/√ 13  + 45/√ 13)

                     = 150/√13

Answer:

13500 and 26500

Step-by-step explanation:

Let Rs x be INVESTED at 4% per annum, then,

Rs 40000-x is invested at 6%per annum

SI at 4% per annum = x*4*1/100

SI at 6% per annum = (40000-x)*6*1/100

Thus, [x*4*1/100] + [(40000-x)*6*1/100] = 2130

= (4x+240000-6x)/100 = 2130

= 4x + 240000 - 6x = 213000

= 240000 - 213000 = 2X

= 27000 = 2x

Thus x = 13500

Hence, 13500 is invested at 4% per annum

And (40000-13500)

=26500 is invested at 6% per annum.
