Answer:b=-10.5, a=31.5
Step-by-step explanation: 3b=-a , -3b=a
a+b =21
-3b+b = 21
-2b=21
b=-10.5
a=-3b
a=-3*-10.5=31.5
Answer:
Number of containers = 271
Number of strawberries left = 4
Explanation:
Total number of strawberries = 2172.
Number of strawberries per container = 8
Number of strawberry container = Total number of strawberries/Number of strawberries per container.
Number of strawberry container = 2172/8
Refer the figure to see division,
Number of containers = 271
Number of strawberries left = 4
It would be 11 squares by 8 squares. The area would be 88.
Yes the graph will show a proportional relationship
