Answer:
95 ; 105
Step-by-step explanation:
Let :
Aanya's time = x
Krish's time = x + 10
Together = 50
Hence
Aanya's rate = 1/x
Krish's rate = 1/(x + 10)
Together rate = 1/50
Hence,
1/x + 1/(x + 10) = 1 / 50
((x + 10) + x) / x(x + 10) = 1/ 50
(2x + 10)/ x² + 10x = 1/50
50(2x + 10) = x² + 10x
100x + 500 = x² + 10x
x² + 10x - 100x - 500 = 0
x² - 90x - 500 = 0
Using the quadratic equation solver :
x = 95.24 ; x = - 5.24
Time can't be negative
Hence, x = 95 (nearest minute)
It takes Aanya 95 minutes Alone a ND
Krishna (95 + 10) = 105 minutes alone
Answer:
Step-by-step explanation:
X = 4
is the answer becuase if you multiply 2 by 4.5 you will get 9 and 9 is the same thing
if you multiply 2 by 5.5 = 11 so thats greater then 9 we want nine to be greater then the number 2x
so 2 x 4 is 8 and 8 < 9 so thats your answer
Answer:
1) f-2g
2) h+3fg
Step-by-step explanation:
1)
- f(4) - g(2) + f(3))
- 4f - 2g + 3f
- 4f - 3f - 2g
- f - 2g
2)
- h(1) + f(1) x g(3)
- h + f x 3g
- h + 3fg
