Question

Room temperature ranges from 20°C to 25°C. Find the range of room temperature in °F. Use the formula F - 32 = 1.8C to convert from the Celsius scale to the Fahrenheit scale.

Answer 1

68 to 77

Explanation:

Substitute the Celsius ranges (20 and 25) in the equation where the C is.

F- 32 = 1.8(20)

F-32= 36

Add 32 to both sides and F= 68

F- 32 = 1.8(25)

F -32 = 45

Add 32 to both sides and F = 77

Answer 2

F = 1.8C + 32 *Replace C with 20
F = 1.8(20) + 32
F = 36 + 32
F = 68

F = 1.8C + 32 *Replace C with 25
F = 1.8(25) + 32
F = 45 + 32
F = 77

Room Temp. in Farenheit ranges from 68 to 77
