Answer:
3 hours
Step-by-step explanation:
Recall:
Distance = speed x time
we are given that speed = 18 km/h and distance = 54 km.
hence,
54 = 18 x time (divide both sides by 18 and rearrange)
time = 54/18 = 3 hours
D : 0.300- 0.006 is correct
A is wrong bec 0.3 doesn’t have the extra 0’s in the end
B is wrong bec the decimal places aren’t aligned
C is wrong bec again, the decimal places aren’t aligned
The inequality is :
4 + x > 6
Answer:
1st option
Step-by-step explanation:
![log( \frac{a {c}^{3} }{b} ) \\ = log(a {c}^{3}) - logb \\ = loga + log{c}^{3} - logb \\ = loga + 3logc - logb](https://tex.z-dn.net/?f=log%28%20%5Cfrac%7Ba%20%7Bc%7D%5E%7B3%7D%20%7D%7Bb%7D%20%29%20%5C%5C%20%3D%20log%28a%20%7Bc%7D%5E%7B3%7D%29%20-%20logb%20%5C%5C%20%20%3D%20loga%20%2B%20log%7Bc%7D%5E%7B3%7D%20%20-%20logb%20%5C%5C%20%20%3D%20loga%20%2B%203logc%20-%20logb)
