3^6=3^3x × 27 find x

Answer»

ANSWER:

x = 1

Step-by-step explanation:

3^6 = 3^3X * 27

=> 3^6 = 3^3x * 3^3

=>3^6 = 3^3x+3 (a^m + a^n = a^m+n)

As the bases are same, we can write,

6 = 3x + 3

=> 3x = 6-3

=> 3x = 3

=> x = 3/3 = 1

The pair linear equation y=3 andy=6 has_solution

Answer»

Answer:

no solution

Step-by-step EXPLANATION:

Given : The PAIR of linear equation y=0 and y = -5

To find : Whether the pair of linear equation y=0 and y = -5 has no solution unique solution or infinitely many solution?

Solution :

The pair of linear equation y=0 and y = -5.

The general equation is of form ax+by=C

We know, If lines turns out to be ax + by = c and ax + by = d

Then we have no solutions as these two lines are PARALLEL.

or Distance between two lines will be

Comparing with given equation,

The EQUATIONS has no solution.

a=0, b=1,c=0,d=-5

The pair of linear equation y=0 and y = -5 has no solution and lines are parallel and distance between them is 5 unit.

25.	the compound interest of a sum of money for 1 year and 2 years are rs 450 and rs 945 respectively. find the rate of interest compounded yearly and he sum
Answer» ANSWER $SI= 100PRT$ $Hence,400= 100PR2$ $⟹PR=20000⟹P= R20000$ $Also,CI=P[(1+ 100R ) 2 −1]420= R20000$ $[(1+ 100R ) 2 −1]$ SOLVING this we GET R=10% ALTERNATE:− $CI for 2 years is=420 Rs.SI for 2 years is=400 Rs.Difference of CI and SI is 420−400=20 Rs.$ $If 2 years SI is 400 Rs.,then 1 year SI is = 2400 =200$ $20 is the what percent of 200.=20×( 200100 )=10%$ $If 510% is 200 Rs. then 100% of that principal.=200× 10100 =2000$ $So the principal is 2000 Rs.Hence,R= PTSI×100 = 2000×2400×100 =10\%$

25.

the compound interest of a sum of money for 1 year and 2 years are rs 450 and rs 945 respectively. find the rate of interest compounded yearly and he sum

Answer»

ANSWER

$SI= 100PRT$

$Hence,400= 100PR2$

$⟹PR=20000⟹P= R20000$

$Also,CI=P[(1+ 100R ) 2 −1]420= R20000$

$[(1+ 100R ) 2 −1]$

SOLVING this we GET R=10%

ALTERNATE:−

$CI for 2 years is=420 Rs.SI for 2 years is=400 Rs.Difference of CI and SI is 420−400=20 Rs.$

$If 2 years SI is 400 Rs.,then 1 year SI is = 2400 =200$

$20 is the what percent of 200.=20×( 200100 )=10%$

$If 510% is 200 Rs. then 100% of that principal.=200× 10100 =2000$

$So the principal is 2000 Rs.Hence,R= PTSI×100 = 2000×2400×100 =10\%$
