Answer:

<em>Answer: B San Francisco</em>

Step-by-step explanation:

It can be read that Geneva is 12°C colder than Nikki's hometown. It can be seen in the table that Geneva is at -3°C.

This means that Nikki's hometown is 12°C hotter than Geneva, thus:

Temperature of Nikki's hometown = -3°C + 12°C = 9°C.

The only city with a temperature of 9°C is San Francisco.

Answer: B San Francisco

This last one!!!! (Maybe)
Andrew [12]

Answer:

142

Step-by-step explanation:

It said to sort it from least to greatest and you did, so we don't need to worry about that. It said ''<u>find the median of the numbers</u>'', which is 137 and 147. Because there are <em>two numbers</em>, we need to work out <em>the middle number</em> of them two.

We start off <em>finding the difference</em> between them <em>which is 10</em> and the middle number of 10 (5). So we just add 5 to 137 (or subtract 5 from 147) which gives us the answer 142
