The temperature at the end of the day was 64 degrees. The temperature had increased twice during the day, once by 8 degrees and another time by 4 degrees.
Which expression shows what the temperature was at the start of the day?
(1 point)
Responses
64 – 8 – 4
64 – 8 – 4
64 + 8 – 4
64 + 8 – 4
64 – 8 + 4
64 – 8 + 4
78 + 5 + 7
To find the temperature at the start of the day, we need to subtract the two increases from the final temperature of 64 degrees.
Therefore, the expression that shows what the temperature was at the start of the day is:
64 - 8 - 4
what is the value of -3 x 4 / -6
To find the value of -3 x 4 / -6, we first perform the multiplication, then divide.
-3 x 4 = -12
Now we divide -12 by -6:
-12 / -6 = 2
Therefore, the value of -3 x 4 / -6 is 2.
