Question

At what temperature will the centigrade thermometer read twice as much as the Fahrenheit scale (with full working)​

Answer 1

Answer:

320⁰ faranhiet

Explanation:

the point where temperature will change the centigrade thermometer read twice as much as the farenheit scale is 320⁰

2C=F

substitute F in 1st formula with 2C from 2nd

it give

2C-9/5C +32

substarcting 9/5C with both side

2C-9/5C =32

2C=10/5C (by subtracting L.H.S)

10/5C-9/5C =32

1/5C=32

multiply 5 to each side

then C =160

therefore

160⁰ celcius = 320⁰ farenheit
