Nonlinear equations in one variable and systems of equations in two variables SAT question

Math · Advanced Math · Medium · Answer it here, explanation included.

The speed of sound in dry air, v, can be modeled by the formula $v equals, 331 point 3 plus 0 point 6 0 6 times T$ , where T is the temperature in degrees Celsius and v is measured in meters per second. Which of the following correctly expresses T in terms of v ?

ExplanationShow

Choice D is correct. To express T in terms of v, subtract 331.3 from both sides of the equation, which gives v – 331.3 = 0.606T. Dividing both sides of the equation by 0.606 gives $the fraction with numerator v minus 331 point 3, and denominator 0 point 6 0 6, equals T$ .

Choices A, B, and C are incorrect and are the result of incorrect steps while solving for T.
