Answer:
The answer is 7/6x - 75.
Step-by-step explanation:
17 - 1/5x +2/3x - 92 + 7/10x
17 - 6/30x + 20/30x - 92 + 21/30x
-6/30x + 20/30x + 21/30x = 35/30x or 7/6x
17 - 92 = -75
7/6x - 75
Answer: false.
Step-by-step explanation:
it's only a terminating decimal if you end up with a remainder of 0.
It’s an Irrational number
When we factorise an expression, we are looking for simple factors that multiply to get the original expression. Usually it is very natural to factorise something like a quadratic in x. For example:
x^2 + 3x + 2 = (x+1)(x+2)
But there are other situations where factorisation can be applied. Take this quadratic:
x^2 - 9x = x(x-9)
This second example is closer to the question in hand. Just like x was a common factor to both x^2 and -9x, we are looking for a common factor to both 6b and 24bc. The common factor is 6b.
Hence 6b + 24bc = 6b(1 + 4c).
I hope this helps you :)
Here, Twice fast means, she takes half time in doing same amount of work.
Let, Anna takes = 2t & Jane takes = t
It would be: 1/t + 1/2t = 1/15
2t + t / 2t² = 1/15
15(3t) = 2t²
2t² = 45t
Divide both sides by t,
2t = 45
t = 45/2
t = 22.5
& 2t = 22.5(2) = 45
In short, Anna would take 45 minutes
Hope this helps!
