The formula for converting from degrees Fahrenheit Fto degrees Celsius C is C = 3 (F - 32). Convert each temperature a. City X temperature: -13°F
7.c
b. City Y temperature: -30°C =
F
c. City Z temperature: -40°C =
F
d. Which city is coldest?

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
