Ok, my algerbra teacher gave me this problem and by just looking at it I can tell what the answer is but he wants me to show how I got the answer in an equation form.
The tempature at 7am on a cold day was -4 degrees Celcius. At 3pm the tempature was 1 degree Celcius. Write and solve an equation to find out how many degrees the tempature rose between 7am and and 3pm.
Suppose that the temperature at 7am was 8 degrees Celcius and at 3pm was 20 degrees Celcius.
- How much did the temperature rise?
- How did you do it?
- Can you write an equation for what you did using S for the temperature at 7am and T for the temperature at 3pm?
- Does the same equation work when the temperature goes from -4 degrees to 1 degree?
