Answer:
1 solution
Step-by-step explanation:
3(2x-7)=9
dustribute: (3)(2)+(3)(-7x)=9
6+-21x=9
subtract 6 from both sides: -21x=3
Divide both sides by -21: x=-1/7
so your 1 solution is x = - 1/7
When the base and the height of a triangle are the same. the hypotenuse is that number times sqrt2.

Answer:
Rs 2163.20.
Step-by-step explanation:
The formula for this is
A = P(1 + r)^t where P is the amount invested, r = the rate (as a decimal) and t = the number of years.
So for rs 2000 we have:
A = 2000(1 + 0.04)^2 = Rs 2163.20
A) 20% of 449 = 89.8
B) 449 - 100 = 349
C) 449 - 75 = 374. 10% of 374 = 37.4. 374 = 336.6
D) 449 - 50 = 399. 20% of 399 = 79.8. 399 - 79.8 = 319.2
Hope this helps! :D
