A negative exponent only means
"Put all of this in the denominator, and make the exponent positive."
So (any number)^negative power =
1 / (the same number)^(the same power but not negative) .
The first few problems on that sheet:
1). 5^-3 = 1 / 5^3
2). 6^-10 = 1 / 6^10
3). (-2)^-5 = 1 / (-2)^5
Got it ? You can do the rest of them now in about 2 minutes.
Answer:
3(2c+d)−d
Distribute:
=(3)(2c)+(3)(d)+−d
=6c+3d+−d
Combine Like Terms:
=6c+3d+−d
=(6c)+(3d+−d)
=6c+2d
=6c+2d

Answer:
I think its 245 but i'm not sure
Step-by-step explanation:
Lets find the common demoninator of them all, Its 30! so 1/3 of 30= 10
3/5 of 30= 18 7/10 of 30= 21 1/2 of 30 = 15
So that means that 7/10 is the biggest out of them all, That means carlos ran the greatest distance!
