b. 8 dollars an hour
c. 30 passengers on one bus
d. 6 degrees a minute
Step-by-step explanation:
You want to divide these down to the smallest rate possible, so you divide.
480/6=80
80 km/hr
56/7=8
8 dollars and hour
270/9=30
30 passengers in one bus
54/9=6
6 degrees in one minute
21/35

divide the fraction by 7
21/7= 3
35/7= 5
3/5

Answer: 27x²yz + 3xz² - 2xy - 2y²z + 2yz²
<u>Step-by-step explanation:</u>
Use the distributive property.
3xz(9xy + z) - 2yz(x + y - z)
= 3xz(9xy) + 3xz(z) -2yz(x) -2yz(y) -2yz(-z)
= 27x²yz + 3xz² -2xy -2y²z +2yz²
