Whats number 9 and 10? It’s okay if you only do one..please help.. Equations for help:
K= C + 273
C= 5/9 (F - 32)
F= (C * 9/5) + 32

9) 75.2°F is less that 82°F so the water is not warm enough for Emma to swim in.

10)Since, 102.2°F is greater than 100°F, Stephen can't go to school today.

Explanation:

9) First, we want to find out 24°C converted to Fahrenheit

           What we want to find                   Equation

                   24°C = ?°F                         F= (C * 9/5) + 32

Second, we have to input our number into our equation

                                    F = (24 × 9/5) +32

Next, we have to use the PEMDAS strategy (ask in the comments if you don't understand!)

       24 × 9/5 =

      24 × 9 = 216                           216÷5 = 43.2

      1   ×   5 = 5

Now, we can't forget to add 32!

43.2 + 32 = 75.2°F

24°C = 75.2°F

75.2°F is less that 82°F so the water is not warm enough for Emma to swim in.

10) For this problem, I'm going to just show the math, so if you have any questions feel free to ask in the comments!

Step 1) 312 = C + 273

           -273        -273

Step 2) 39 = C or C = 39

Step 3) F = (39 × 9/5) + 32

Step 4) F = (351/5) + 32

Step 5) F = 70.2 + 32

Step 6) F = 102.2

Since, 102.2°F is greater than 100°F, Stephen can't go to school today.(and should think about getting a regular thermometer ;)

Hope this Helps! :)
