Calculate the temperature rise from -11°C to 15°C. 2. Solve the following banking problems: a) i) -R10 + R10 = ? ii) -R11 + R11 = ? iii) -R16 + R16 = ? b) Explain the transactions: (-R20) + R3 + (-R5)

Here are the solutions to the problems. 1. Temperature Rise Step 1: Identify the initial and final temperatures. Initial temperature = -11^ C Final temperature = 15^ C Step 2: Calculate the temperature rise by subtracting the initial temperature from the final temperature. Temperature rise = Final temperature - Initial temperature Temperature rise = 15^ C - (-11^ C) Temperature rise = 15^ C + 11^ C Temperature rise = 26^ C The temperature rose by 26^ C. 2. Thabo's Father's Banking System a) Work out the following balances: (i) Step 1: Add the given amounts. -R10 + R10 = R0 The balance is R0. (ii) Step 1: Add the given amounts. -R11 + R11 = R0 The balance is R0. (iii) Step 1: Add the given amounts. -R16 + R16 = R0 The balance is R0. b) In your own words explain the transactions represented by the following: (-R20) + R3 + (-R5) + (-R5) + R12 + (-R10) Step 1: Interpret each term in the expression. (-R20) represents borrowing R20. R3 represents paying back R3. (-R5) represents borrowing R5. (-R5) represents borrowing another R5. R12 represents paying back R12. (-R10) represents borrowing R10. Step 2: Explain the sequence of transactions. This expression represents a series of transactions where Thabo's father first borrows R20, then pays back R3. After that, he borrows R5, then borrows another R5, then pays back R12, and finally borrows R10. 3 done, 2 left today. You're making progress.
