Question

Water boils at 100 degrees or 200 Fahrenheit.water freezes at 0 degrees Celsius or 32 degrees Fahrenheit.if the weather forecaster says it will be 25 degrees Celsius today,write and solve a linear equation to find what Fahrenheit temperature this is.

Answer 1

X = degrees Celcius
Y = degrees Fahrenheit

(X × 9/5) + 32 = Y

Y = mx + b
Y = 9/5X + 32

That is the formula of conversion, translated into a linear equation.


Y = 9/5(25) + 32

Y = 77 Degrees Fahrenheit
