Answer:
x=-58/15
Step-by-step explanation:
distribute first 10-2.5x+12=21-10x-28
Simplify(add the numbers) 22-2.5x=-7-10x
move the variable to the left side 22-2.5x+10x=-7
move the constant to the right side -2.5x+10x=-7-22
simplify like terms 7.5x=-29
divide by 7.5 x=-58/15
alternate forms are x=-3 13/15 or x=-3.86
<h3>
Answer:</h3>
932°F to 36032°F
<h3>
Step-by-step explanation:</h3>
Celsius and Fahrenheit are both measures of temperature. However, Celsius is a metric measurement, and Fahrenheit is used in the USA primarily.
Conversion Formula
To convert the Celsius measurements to Fahrenheit we can use the formula:
So, in this formula, you can plug in whatever Celsius value you have in and solve for Fahrenheit. To convert from F to C you can use the second formula:
Solving for Fahrenheit
Now that we have the formula, we can plug in the 2 Celsius values to find the new range.
First, plug 500°C in
Next, multiply the terms within the parentheses
Finally, add the last terms
Then, plug in 20000°C
- (20000°C × 9/5) + 32 = °F
Next, multiply the terms within the parentheses
Lastly, add the terms together
This means that, in Fahrenheit, the temperature range of the welder's electrical arc is 932°F to 36032°F. This is a total range of 35100°F.
