This is a very good question to know about. People who make tests really like it.
The way to solve it is to make the slower car stop and use the difference in speed = to the rate. then do it as an ordinary d = r*t problem.
The difference in speeds is 44 - 36 = 8 miles/ hour.
d = 260 miles
r = 8 mph
t = ???
t = d/r
t = 260/8
t = 32.5 hours.
Thats 32 1/2 hours.
<h3>Answer:</h3>
$200
<h3>Explanation:</h3>
Let p represent the price last year. Then the price this year is ...
... (price this year) = p + 15%×p
... = p + 15/100×p = 1.15p
The price after the employee discount is ...
... (price this year) - 25%×(price this year)
... = (price this year)×(1 - 25/100) = 0.75×(price this year)
Then the price paid is ...
... $172.50 = 0.75×(1.15p) = 0.8625p
Dividing by the coefficient of p, we have
... $172.50/0.8625 = p = $200
The price last year was $200.
a. (2x + 6) - 4 represents how to find the area of the table cloth. (to be honest, I'm not sure why you have to subtract the lace, or what I'm assuming is the lace...)
b. 2x + 6 represents how to find the area of the table cloth.
c. 2x represents the x length getting multiplied by 2, since there are 2 sides.
I hope this helps just a little bit though. I'm sorry I could get part a very well.
It's 12. :) A negative sign within an absolute value doesn't matter, so the number will be positive if it's by itself.
