1. To find the temperature at 4:00 P.M., we can add the change in temperature to the starting temperature of -28.
Starting temperature: -28 degrees
Change in temperature: +38 degrees (it rose by 38 degrees)
To find the temperature at 4:00 P.M., we add the starting temperature and the change in temperature:
-28 degrees + 38 degrees = 10 degrees
So the temperature at 4:00 P.M. was 10 degrees.
2. To find the total number of pounds gained or lost by the three friends, we need to add up the individual changes in weight.
Friend 1: Lost 5 pounds
Friend 2: Gained 3 pounds
Friend 3: Lost 4 pounds
To find the total, we add up the changes in weight:
5 pounds lost + 3 pounds gained + 4 pounds lost = 12 pounds
So the total number of pounds gained or lost by the three friends is 12 pounds.
The first is right; the second is wrong.
Be sure you indicate whether the friends lost or gained.
No.
one had lost 5 pounds,
one had lost 4 pounds
another had gained 3 pounds
Be sure you indicate whether the friends lost or gained.
-9 is how much lost pounds and 3 is how much gained?
-9 + 3 = -6
The three friends together lost a total of 6 pounds.
