So 9x<18 can be factored out into
9(x)<9(2)
you can divide both sides by 9
x<2
so the solution is any number more than 2, but not 2

We need to do a system of equations here.
x + y = 275 (if you travel <em>x</em> km by bike and <em>y </em>km by bus, then you travel 275 km as given in the problem)
y = x + 55 (the problem stated that they were bussed (y) the amount they biked plus 55 more km (x + 55))
The second equation is already solved for y. So, we can plug it in to the first equation.
x + (x + 55) = 275
2x + 55 = 275 [combine x terms]
2x = 220 [subtract 55 from both sides]
x = 110 [divide by 2 to isolate x and solve for it]
Now we know that x is 110, the distance they traveled by bike.
And that's what we needed to answer the problem!
Answer:
Breyana paid 88% of the dress's original price.
Step-by-step explanation:
We are given the following in the question:
Let x be the original price of dress.
The dress is on sale for 20%.
Price of dress after discount =
Breyana will also have to pay 10% sales tax on the discounted price of the dress.
Price of dress after discount =
Total cost of dress =
We have to calculate percentage of original price paid by Breyana
Thus, Breyana paid 88% of the dress's original price.
-5 is the answer to your question because all you do is plug in -2 into your equation for x
