Answer: 110/17
Step-by-step explanation: You take you 6 and times it by 17 and + 8 because the equation is saying 17/17 6 times plus the 8/17,So 6 times 17=102
102+8=110 and then you take the 110 and put it over the 17 so now you have your answer: 110/17
Answer:110/17
Step-by-step explanation:
multiply the denominator by the whole number 6*17=102
then add your numerator to your answer 102+8=110

(2x^{2} - 5x + 3) - (-x^{2} + 4x - 5)
Answers
Answer:
3x^2 - 9x + 8
Step-by-step explanation:
To simplify:
- Distribute the -1 into the second term.
- Collect and combine like-terms (terms with the same variables or powers)
The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)
After distributing the -1, the equation becomes:
- (2x^2 - 5x + 3) + (x^2 - 4x + 5)
The like-terms are:
- 2x^2 and x^2
- -5x and -4x
- 3 and 5
Combine the like-terms:
- 2x^2 + x^2 = 3x^2
- -5x - 4x = -9x
- 3 + 5 = 8
Substitute the simplified like-terms into the expression, in descending order:
- 3x^2 - 9x + 8

1. My amplifier uses a filament that requires a maximum of 5 volts at a current of 15 amperes.
Calculate the resistance of the tube. (Round to no more than two numbers to the right of the decimal)
2. How many ohms of resistance are present in a light bulb that draws 2 amperes at 120 volts?
3. A 250 watt radio will draw how many amps when operating on 240 volts? (Round to no more than two numbers to the right of the decimal)
Answers
Resistance = Current/Voltage.
Now coming to the questions that are given.
1. In this question,
Current = 15 amperes
Voltage = 5 volts
Then
Resistance = 5/15
= 1/3
= 0.33 ohms
So the resistance of the tube will be 0.33 ohms
2. Given information's are noted below
Current = 2 amperes
Voltage = 120 volts
Resistance = 120/2
= 60 ohms
So 60 ohms of resistance is present in the bulb.
3. Given information's
Current = 250 watt
Voltage = 240 volts
Resistance = 250/240
= 25/24
= 1.04 ohms.
The radio will draw 1.04 ohms.
