$148-$123= 25 is the answer to your equation above
Answer:48x^15y^10z^4
Step-by-step explanation: multiply similar terms i.e 4×6×2=48
X×x^6×x^8=x^15
y×y^2×y^7=y^10
z^4×z^0=z^4
If y∞x then y=kx where k is constant to find k
k=y/x then substitute the values
k=30/-10=-3 to find x when y is 4
x=y/k=4/-3=-4/3 option A
Answer:
3 hours on the city roads and 4 hours on the other roads
Step-by-step explanation:
580 (total miles driven) - 400 (4 hours of driving 100km/h) = 180 (miles left)
180 (miles left to drive) / 60 (km/h) = 3 (hours driven at the speed of 60km/h)
I hope this helps :)
