Answer 1

The change in the water level of Sweetgum Pond over the first two weeks of June was an increase of 3 centimeters, accounting for a decrease of 4 centimeters in the first week and a rise of 7 centimeters in the second week.

Step-by-step explanation:

Kylie is studying the change in the water level of Sweetgum Pond as part of a summer science experiment. In the first week of June, the water level changed by -4 centimeters (decreased). The following week, after storms every day, the water level rose 7 centimeters. To find the total change in water level over the first two weeks of June, we simply add these two changes together:

• Change in first week: -4 cm
• Change in second week: +7 cm

Adding these together:

-4 cm + 7 cm = 3 cm

Therefore, the water level in Sweetgum Pond increased by 3 centimeters over the first two weeks of June.
