Y/x=k
when y=9, then x= -3
9/-3=-3
⇒ k= -3
3x(2) + 2(2x - 20) = 16 - 2x(2)
6x + 4x - 40 = 16 - 4x
10x - 40 = 16 - 4x
14x - 40 = 16
14x = 56
x = 4
Hope this helps! ;)
Answer: 0.6
Reason: 3 divide by 5 is 0.6
5^0=1
Any exponent to zero power equals 1
322kmh x1000= 322,000 meters per hour
That is the relationship between km and m
Because we are turning bigger units into smaller we the number will increase.
example 2 wks = 14 days two became 14 - it increased
