Answer:
Average speed=52 miles per hour
Step-by-step explanation:
The expression for calculating the average speed is as follows;
S=D/T
where;
S=average speed
D=distance traveled
T=time taken
In our case;
S=unknown
D=130 miles
T=2 1/2 hours=2.5 hours
replacing;
Average speed=130/2.5=52 miles per hour
Average speed=52 miles per hour
Let x be the length of third side.
12 + x > 13
x > 1-------------(1)
13 + x > 12
x > -1 ------------(2)
by combining (1) and (2)
we have x > -1
Step-by-step explanation:
Nickels = 112 * 3 / (3 + 4 + 7) = 24.
Answer:
34800
Step-by-step explanation:
As, the nearest hundred to 766 is 800.
Suppose the equation went like this
-12 -24= x
You would essentially just add them together and put a negative sign in front of it so the answer would be -36. But once you start dealing with parentheses and brackets it get more complicated than that. Comment if you have any more questions :)
