Due to evaporation,the water level in Wesley’s aquarium dropped 2cm a week during the first three weeks in July.What integer represents the change in water level during the three-week period?
-2*3 = -6
To find the change in water level during the three-week period, we need to add up the individual changes in water level for each week.
The water level dropped 2cm per week for three weeks. We can represent this as:
-2 cm/week + -2 cm/week + -2 cm/week
To add these integers, we simply sum them:
-2 + -2 + -2 = -6
Therefore, the integer that represents the change in water level during the three-week period is -6.
The change in water level during the three-week period can be calculated by adding up the individual changes in water level for each week.
Since the water level dropped 2cm each week for three weeks, the total change in water level can be calculated as:
2 cm + 2 cm + 2 cm = 6 cm
Therefore, the integer that represents the change in water level during the three-week period is -6 cm (as the water level dropped).
