Answer:
ok!
Step-by-step explanation:
the mean is 8.125 and the median is 7
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!
Answer: 
Step-by-step explanation:
Subtract 490 from both sides
Then flip
multiply both sides by
to cancel out 
Thus giving you -735 as your
.
Then you plug it back into the equation to solve.
F(x) = 2|x| + 3x
f(1) = 2|1| + 3(1)
f(1) = 2 + 3
f(1) = 5
