The given equation is
We need to solve the equation for q.
<u>Value of q:</u>
The value of q can be determined by solving the equation
for q.
Thus, subtracting both sides of the equation by r, we get;

Now, dividing both sides of the equation by b, we have;

Simplifying the terms, we get;

Therefore, the value of q is 
Hence, Option B is the correct answer.
Answer:
w > -14
Step-by-step explanation:
Divide both sides by -6.
-6w/-6 = w
84/-6 = 14
Since it's an equality, if the coefficient of the variable is negative, when you divide the sign flips to the opposite.



Therefore, the value of x is 7.375.


Hence verifed.

Answer:
Given:-
The length of copper wire (L) = 270 cm
Area of cross-sectional (A) = 0.030 
and specific resistance (ρ) =
ohm-cm.
Use the formula R=(Specific resistance*L)/A, to calculate the Resistance(R)
then,
ohm
Simplify:
R = 0.0162 ohm =
ohm
Therefore, the resistance of copper wire is,
Ω
