First set up the equation.
x + 3x = 648
Then solve for x.
4x = 648
Divide both sides by 4.
x = 162. So the answer for the system would be $162 and the price for the games would be $486. Add the two up to check your work and you will get $648. Hope this helped!

Answer:
24 Years
Step-by-step explanation:
Rule of 72 is an approximation that you can use to estimate the time it will take for something to double in value at a compound rate of interest
use the following equation
72/(i*100)
we have
72/(.03*100)
72/3=24
Equation: x + x + 6 = 2x = 25
smallest side is 4.75 units
largest size is 4.75 + 6 = 10.75 units
3rd side is 2(4.75)= 9.5 units
smallest side is x
largest size is x + 6
3rd side is 2x
-----------------------------------
4x + 6 = 25
-6 -6
<u>4x</u> = <span><u>19</u>
</span> 4 4
x = 4.75 is the smallest side
smallest side is 4.75 units
largest size is 4.75 + 6 = 10.75 units
3rd side is 2(4.75)= 9.5 units
Answer:
12% decrease
Step-by-step explanation:
You need to answer this question: What percent of 500 is 440? If you get the answer in a percentage, it will be the percent decrease of this situation.
The answer would be 88%. Meaning 440 is 88% of 500.
This would also mean 500-440 is 100%-88%. 60 is 12%.
Since the difference between 500 and 440 is 12% the answer is above.
