Answer:
r=s+5
Step-by-step explanation:
So, letsgo over what we know:
The regular price is r
The sale price is s
Now lets compare the difference between r and s:
10r = 5s
20r = 15s
30r = 25s
What is the difference between the r and s value in each situration?
Well, from what I can see, r is always 5 more than s.
This can be writen as:
r = s+5\
So this is our equation, for if you plug in any number for s, you will get an accurate r value.
For instance, if you say s is 25:
r=25+5
=
r=30
This looks just like the 30r=25s in the table above.
So:
r=s+5
Hope this helps! :)
15 = 0.25x
1500 = 25x
60 = x
The original price was $60.
this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5
1)We solve the first equation:
2x-1=5
2x=5+1
2x=6
x=6/2
x=2
2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2
The solutions of this equation /2x-1/=5 will be: x=3 and x=-2
Answer: x=3 and x=-2
Answer:
x = -8
