If you would like to find the amount of hours and the distance, you can calculate this using the following steps:

y = y
45x + 20 = 35x + 60
45x - 35x = 60 - 20
10x = 40
x = 40 / 10
x = 4 hours

y = 45x + 20 = 45 * 4 + 20 = 200 miles
y = 35x + 60 = 35 * 4 + 60 = 200 miles

The correct result would be 4 hours, 200 miles.

Can someone. show me how to work these math prob?
yan [13]
You did #1 correctly.

#2).  The question gives you the equation, and the numbers to use for 'a' and 'b', and it just wants you to plug in those numbers and do the arithmetic.

It says: The number of tiles needed is  (a²) divided by (b²).

Then it says: a = 96  and  b = 8.   I know you can handle that !

Number needed = (96)² divided by (8)² .
Use your calculator: 
(96)² = 9,216
(8)² = 64
Number needed = (9,216) divided by (64) = 144 tiles

#3).  While reading #3 carefully, I realized that there's a table printed near it,
and you need the table to do the problem.  But you can't see the table in the
picture, so we're stuck on this one.
