Answer:
25-10=15
Step-by-step explanation:
Hello,
I am hoping I can help.
Here is how I solved this.
60 miles 60 minutes
1 mile 1 minute
100 miles 100 minutes
100 miles - 60 miles = 40 miles
100 minutes - 60 minutes = 40 minutes
1 hour and 40 minutes for train ride.
4:00 + 1:40 = 5:40
The train will arrive at 5:40 pm.
I hope this helped!
Best regards,
Jessi
The answer is Letter B - 2, 8, 26
<span>Given: an=3an-1+2 ; where a2=8
Required: First three terms of the sequence - a1, a2, a3
Solution:
You need to work back to get a1 since the given is a2.</span><span>
To work back, minus 2 from 8 first before dividing the number by 3.
a1 = 8 - 2
a1 = 6 / 3
a1 = 2
In getting a3, multiply the given 8 by 3 then add 2. </span>an=3an-1+2 : a3=3(8)+2<span>
a3 = 8 x 3
a3 = 24 + 2
a3 = 26</span>
<span>(1,625) No
(0,-25) No
(-1,-1) No
Think about what an integer exponent means for an negative base and you'll understand this problem. For instance the powers of -25 would be
-25^1 = -25
-25^2 = (-25) * (-25) = 625
-25^3 = (-25)*(-25)*(-25) = -15625
and so on, giving 390625, -9765625, 244140625, etc.
But that's a different subject. For the ordered pairs given, let's check them out.
(1,625)
-25^1 + 1 = -25 + 1 = -24. And -24 is not equal to 625, so "No".
(0,-25)
-25^0 + 1 = 1 +1 = 2.
Note: Any real number other than 0 raised to the 0th power is 1. And 2 is not equal to -25, so "No".
(-1,-1)
-25^(-1) + 1 = 1/(-25^1) + 1 = 1/-25 + 1 = 24/25.
And 24/25 is not equal to -1, so also "No".</span>
I think 710 is the answer
266+266+89+89= 710
