Answer:
The solution of the equation is 
.
Step-by-step explanation:
The previous equations is for the Ohm's Law, which states that current (
), measured in amperes, is directly proportional to the voltage (
), measured in volts:
The complete formula is:
(1)
Where 
is the electric resistance, measured in ohms.
Solving for means that we need to clear within the formula, a process that will be presented step-by-step:

4) 
Existence of multiplicative inverse.
5) 
Modulative property.
6) Definition of division/Symmetric property/Result
The solution of the equation is .
33,194 becuase if you multiply 2742 by 7 you would get the answer 33,194
Answer:
(5,-5)
x=5
y=-5
Step-by-step explanation:
How to solve using elimination method.
First, add the two equations.
2x - 3y = 25
+ <u>5x + 3y = 10</u>
7x=35
The y values got eliminated.
Next, divide 7 from both sides.
7x/7=35/7
x=5
Next, plug-in x=5 into one of the equations.
2(5) - 3y = 25
10-3y=25
Subtract 10 from both sides.
-3y=15
Divide -3 from both sides.
y=-5
Remember a positive divided by a negative is a negative.
Hope this helps!

There are 3 in. of snow on the ground when it begins to snow 0.5 in./h.
Initial depth of snow = 3 in.
it begins to snow 0.5 in./h. The constant rate of snow is 0.5. So slope = 0.5
Let x be the number of hours
y be the total depth of the snow
To frame linear equation we use y=mx+b
where m is the slope and b is the y intercept (initial depth of snow)
We know m=0.5 and b=3
Replace it in the equation
y = 0.5x + 3
The linear equation that represents the total depth of the snow(y), in inches, after x hours
is y= 0.5x + 3
