6(x+9) = 7(x-4)
6x+54 = 7x-28
54 = x-28
82 = x
The number is 82.
I believe by the first equation they are referring two a representation of the total amount of money made up by the two types of coins. I found this to be 0.05x + 0.10y = 3.50
In my work I solved for the amount of each coin- I assume this is what the final step of your problem entails. If you need any help understanding/ I misinterpreted something please feel free to comment and ask :)
#5c coins or x= 36
#10c coins or y= 17
The length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.
<h3>What is an ampere circuit?</h3>
Ampere's circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.”
Here we have a cable rating of 120-volt/15-amp so if the 1-ampere circuit means 1 watt per foot cable will be used for the 1-ampere circuit.
A Total of the 15-ampere circuit means 15 watts needed so we are using 2.5 watts per foot.
Hence the length of the cable will be 6 feet which can be installed 120-volt/15-amp circuit.

Answer:
Slope: 7
y-intercept:-6
Step-by-step explanation:
The equation of the line in Slope-intercept form is the following:
Where "m" is the slope of the line and "b" is the y-intercept.
You have the equation of the given line:
You can observe that it is written in Slope-intercept form, therefore, you can identify that the slope and the y-intercept are the following:
