9/12 = -4/y
-48 = 9y
y = -16/3 assuming function is linear
Kong took
15% fewer seconds than Nolan took. So Kong took
100%−15%=85%
85/.85=.85*?/.85
100=?
Which means that Nolan took 100 seconds.
This is all from Khan Academy so it's correct!!
Hope this helps!!
Simplify the following:
(-6 (-8)×2×3 x x x x)/(3×4)
(8 x×2 x (-6) x×3 x (-1))/(3×4) = (8 x^4×2 (-6)×3 (-1))/(3×4):
(-6 (-8)×2×3 x^4)/(3×4)
8×2 = 16:
(-6 (-3)16 x^4)/(3×4)
16 (-6) = -96:
(-3-96 x^4)/(3×4)
-96 (-3) = 288:
(288 x^4)/(3×4)
3×4 = 12:
(288 x^4)/12
