8v + 8b = 240
4v + b = 54
------
Modify:
8v + 8b = 240
8v + 2b = 108
------
Subtract and solve for "b":
6b = 132
b = 22 (# of students in each bus)
-----
Solve for "v":
4v + b = 54
4v + 22 = 54
4v = 32
v = 8 (# of students in each van)
Answer:
3.14
Step-by-step explanation:
-8 - 92.5 = -100.5, and then -100.5/(-32) = 3.14
Alternatively, type in (-8 -92.5)/(-32)
The larger number is 5.
<u><em>Explanation</em></u>
Lets assume, the larger number is
and the smaller number is 
As the sum of two numbers is 9, so...

Now, the sum of their squares is 41, so....

First, solving equation (1) for
....

Now, plugging this
into equation (2) , we will get...

If
then 
So, the larger number is 5.
An underestimate of 532 times 11 is 5852
Answer:
$9
Step-by-step explanation:
If you do 13x1.50= 19.5
28.50 - 19.5 = 9
