Answer 1

Answer:

a) no

b) 21

Step-by-step explanation:

a) sum of temperature of

Fairbanks+Anchorage=(-10+15)°F=5°F

&sum of temperature of Barrow+

Juneau=(-13+24) °F=11°F

5°F<11°F

therefore, sum of temperature of fairbank and Anchorage is less than sum of barrow and Juneau temperature

b) difference of temperature of Juneau and Anchorage=(24-15)°F=6°F

temperature of the barrow =-13°F

therefore temperature to be increased =-13+x=9

=>x=21°F
