Answer:
1100 minutes
Step-by-step explanation:
Equation: 35=.05x-20

Answer:
Yes
Step-by-step explanation:
There are 10 mm in 1 cm.
We have 300 mm, so let's convert this to cm by using a proportion:
, where x is the number of cm in 300 mm.
Cross-multiplying, we get: 10x = 300, so x = 30 cm.
Clearly, 30 cm > 3 cm, so yes, 300 mm is greater than 3 cm.
Hope this helps!
