Answer:
1) 5.75
2) -6.25
3) 3.75
4) -3.5
5) decreased by 3.3 gallons
Step-by-step explanation:
1) [tex] 8 - 2.25 = 5.25[/tex]
2) [tex] - 3\frac{1}{2} + ( - 2\frac{3}{4} )[/tex]
[tex] = > \frac{ - 7}{2} + \frac{ - 11}{4} [/tex]
[tex] = > \frac{ - 25}{4} =6.25[/tex]
3) [tex]1 \frac{1}{4} + 2 \frac{1}{2} [/tex]
[tex] = > \frac{5}{4} + \frac{5}{2} [/tex]
[tex] = > \frac{15}{4} = 3.75[/tex]
4) [tex] - 9.5 + 6 = - 3.5[/tex]
5)
Amount of water collected on a month = 8.4 gallons
Amount of water used in garden = 5.2 gallons
Amount of water used in flowers = 6.5 gallons
Total amount of water used up = 5.2 + 6.5 = 11.7 gallons
Dat gurl saved 8.4 gallons in that month & she used up 11.7 gallons water. So, the rainwater supply was decreased by (11.7 - 8.4) = 3.3 gallons
