Answer:
8.8
Step-by-step explanation:
Add all numbers together to get 132
All number of numbers together to get 15
Divide the sum of all numbers by the number of numbers:
132/15
8.8

Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3
Answer:
1000 miles
Step-by-step explanation:
We will use the distance equation to find the answer to this problem.
D = RT
Where
D is distance
R is rate
T is time
At 250 miles per hour, suppose it takes t hours to go to st. paul. Thus, we can write:
D = 250t
Now, at 200 mi per hour, it takes 1 hour longer, so the time is "t + 1", so we can write:
D = 200(t+1)
We can equate both and see:

Now, we solve for t first:

We want the distance of St. Paul, so we can use any equation. lets use the 1st equation:
D = 250t
we know t = 4
so
D = 250 * 4 = 1000 miles
Distance to St. Paul is 1000 miles
