The first option is

The second option is

So, neither of them is equivalent to 
Answer:
3(n-5)=2n+16
Step-by-step explanation:
3 lots of 'n' <em>and </em>5 means 3 times both values so these values are put into a bracket with a common multiplier (ie. the 3)
3(5 - n)
16 more than 2 lots of 'n' means that n has to be doubled. n + n = 2n. add 16 to this and we have
2n + 16
if these values are both equal (hence why they are in an equation) then all that is needed is for them to be set equal alongside each other.
3(n-5) = 2n+16

Answer:
x=5
Step-by-step explanation:
7x-10=25
+10 +10
7x=35
divide by 7 both sides
Using the given formula speed = distance over time:
Speed = 70 miles / 3 hours
Speed = 23.33 miles per hour
Convert miles per hour to meters per hour:
1 mile = 1609 meters:
23.33 miles x 1690 meters = 37,543.33 meters per hour.
Now convert meters per hour to meters per second:
1 hour = 3600 seconds:
37,543.33 / 3600 = 10.4 meters per second.
