Answer 2

Solving the Equation -17.8x = 294.3

To solve the equation -17.8x = 294.3 and find the value of x, we can use the following steps:

1. Isolating x: First, we need to isolate the variable x by dividing both sides of the equation by -17.8.

The equation becomes: x = 294.3 / -17.8

2. Calculating the Value of x: Now, we can calculate the value of x using the given equation.

x = -16.5168539326

Therefore, the value of x is -16.5168539326.

Checking the Given Numbers

Now, let's check which of the given numbers 312.1, -312.1, 276.5, and -276.5 is the root of the equation -17.8x = 294.3.

- Checking 312.1: Substituting x = 312.1 into the equation: -17.8 * 312.1 = -5547.58 This does not equal 294.3.

- Checking -312.1: Substituting x = -312.1 into the equation: -17.8 * (-312.1) = 5547.58 This does not equal 294.3.

- Checking 276.5: Substituting x = 276.5 into the equation: -17.8 * 276.5 = -4917.7 This does not equal 294.3.

- Checking -276.5: Substituting x = -276.5 into the equation: -17.8 * (-276.5) = 4917.7 This does not equal 294.3.

Conclusion

None of the given numbers 312.1, -312.1, 276.5, and -276.5 is the root of the equation -17.8x = 294.3. Therefore, the solution to the equation does not match any of the given numbers.
