Question

the table gives the temperature (in °f) in five cities at 6 a.m. on the same day. use the table to answer the questions.

city	st. louis	san antonio	boston	nome	toronto

(a) by noon, the temperature in boston had risen by 14 °f. what was the temperature there at noon?

(b) how much lower was the 6 a.m. temperature in nome than in san antonio?

• °f lower

Explanation:

Part (a)

Step1: Find Boston's 6 a.m. temp

From the table, Boston's 6 a.m. temperature is \(-8^\circ\text{F}\).

Step2: Add the rise in temperature

The temperature rose by \(14^\circ\text{F}\), so we calculate \(-8 + 14\).
\(-8 + 14 = 6\)

Step1: Find 6 a.m. temps of Nome and San Antonio

Nome's 6 a.m. temperature: \(-28^\circ\text{F}\)
San Antonio's 6 a.m. temperature: \(63^\circ\text{F}\)

Step2: Calculate the difference

To find how much lower Nome's temp is, subtract Nome's temp from San Antonio's: \(63 - (-28)\).
Subtracting a negative is adding the positive: \(63 + 28 = 91\)

Answer:

The temperature in Boston at noon was \(6^\circ\text{F}\).
