Answer:
<h2>B. 3,4 Volt</h2>
Step-by-step explanation:
Here we need to use Ohm's Law, because we have electric current, voltage and resistances. This law state: 
So, first we need to calculate the total resistance to then find the voltage. The resistances can be placed in two ways: in parallel, in series.
The pair 4 and 8 ohms are parallel, so we solve:


Which is, 
Now, this total resistance of parallels ones is placed in series with the 3 ohm resistance, in this case we just sum, because they are in series:

Now that we have the total resistance of the circuit, we use the Ohm's Law:

Therefore, the right answer is B.
Answer:
A. $9
Step-by-step explanation:
87÷3= 29
29-20=9
Answer: x = - 111
Step-by-step explanation:
- Add the like terms on the right side of the equation. 45 + 85 = 130. 130 - 180 = - 50. The equation simplifies to x + 61 = - 50
- Subtract 61 on both sides. x = - 111
Answer:
-24 < t
Step-by-step explanation:
12t - 8 < 16 + 13t <----- subtracts 13t and 12t
-8 < 16 + t <----- subtract -8 and 16
-24 < t
Answer:
For number 1, it's 3(x^2+1)
Step-by-step explanation:
Step 1: Identify the GCF of the polynomial.
Step 2: Divide the GCF out of every term of the polynomial.
