Answer:
Yes
Step-by-step explanation:
1) lets make an equation where "x" would be the number of levels I played
So since we already used 5.166 mins of my free trial i have to subtract it:
60-5.166=54.83
I have 54.83 mine left
We xan represent the time it takes to play each level as -7.33x(since we are taking away time from the free trial by playing each level it would be neg.)
So
54.83-7.33x: This is our expression
X=6
So
54.83-7.33(6)=
54.82-42.98=10.84
I will have 10.84 mins left after i play 6 levels so yes, I can play 6 levels
Hope this helps!

Answer: 35% decrease
Step-by-step explanation: In this problem, we're asked to find the percent decrease if the price of an item changes from $180 to $117.
To find the percent decrease, we use the following formula.
The <em>amount of change</em> is the difference between the two numbers which in this case is 180 - 117 and the <em>original number</em> is the first number which is 180.
The difference between 180 and 117 is 63 and we put that over 180.
Now we have .
Now, we either use a calculator or long division. I will use my calculator but if you don't have access to one, long division is always available.
63 ÷ 180 = 0.35
Now since we want to find the percent increase, we need to change 0.35 to a percent and we can do this by moving the decimal point two places to the right.
0.35 ⇒ 35%
So when the price changes from $180 to $117, it is decreased by 35%.
Answer:
No.
Step-by-step explanation:
A function must past the Vertical Line Test. We know that our equation x² + y² = 5 is a circle, and so some x-values have the same y-values, etc. Since not every x-value has its own y-value, our equation is <em>not</em> a function.
We can see this using a graph:
Since the vertical line test passes 2 points with the same x-value, it is not a function.
