The temperature at 8: 00 a. m. was –6°f. by 4: 00 p. m. the temperature was 17°f. what was the change in temperature from 8: 00 a. m. to 4: 00 p. m.?

Step-by-step explanation:

We have been given that the temperature at 8:00 a.m. was –6°F. By 4:00 p.m. the temperature was 17°F.  We are asked to find the change in temperature from 8:00 a.m. to 4:00 p.m.

The change in temperature would be final temperature minus initial temperature.

Therefore, the change in temperature from 8:00 a.m. to 4:00 p.m. is 23 degree Fahrenheit.

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60
