.29 is bigger.
If you convert 1/5 to a decimal (or simply solve it!) you will end up with .2 or .20
Which is obviously smaller than .29
The trick is to write appropriate equations and then solve the system of equations you've created.
"sum of two numbers is -5:" x + y = -5
"difference is -1:" x-y = -1
Add these two equations together. This will cause y to drop out, and you will be left with an equation in x alone:
2x = - 6, so x = -3. Subst. -3 for x in either equation, above, and find the corresponding y value.
Then write your solution as (-3, y ) (write in your value for y).
Answer:
(B) $5.25
Step-by-step explanation:
We can create an equation to represent this problem.
Let's assume
is the cost of a ferris wheel ticket,
is the cost of a snow cone, and
is the cost of a cotton candy.
We bought two ferris wheel tickets, one snow cone, and one cotton candy. After a discount of 6 dollars, the price was 12.75.
This makes the equation 
Since we know the value of each ferris wheel ticket and the snow cone, we can simplify our equation by substituting in these values.

We can now subtract 7.5 from both sides to get the value of
, the cotton candy price.

So the cotton candy cost $5.25.
Hope this helped!
