Answer:
depends.
Step-by-step explanation:
Evaluating a question depends on the question given. To simplify an answer, you need to find the simplest answer, this process also depends on what question you're given, for example, if you simplify 4/8 (four eighths), it would be 1/2 (one half).
Answer:
Step-by-step explanation:
so we see the two line of the same length of 14, which tells us that the lengths of 5x and 7x-8 have to be the same length. so we know we can set them equal to each other. Often times that's the key to math problems , finding where you can set things equal.
5x = 7x-8 ( subtract 5x from both sides and then add 8 to both sides )
8 = 2x ( divide both sides by 2 )
4 = x
nice this looks right too , both sides add to 20 :)
The answer is whatever the other guy said
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!
Hope this helps but I think the answer could be : 157+25m=50+60m
