Whatever you do to one side you do to he other
Answer:
344
Step-by-step explanation:
Um..... sorta confusing, but I think you are only allowed to increase by 10 each time, so then you need to add 20 to make 344, where the units digit and tens digit are the same
V = 4πr³/3
Substituting,
V = (4/3)π(3 cm)³
V = 36π cm³
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:
x = 3 + y
Step-by-step explanation:
4x - 2y = 6
~Add 2y to both sides
2x = 6 + 2y
~Divide 2 to everything
x = 3 + y
Best of Luck!
