It's hundred times bigger than the real carpenter bee.
Step-by-step explanation:
(3х - 7y = 13)×-2
6х + y = 7
-6х +14y = -26
6х + y = 7
15y=-19
y=-19÷15=-1.26
6x+-1.26=7
6x=7+1.26
6x=8.26
x=1.37
Answer:
4 Hours
Step-by-step explanation:
1). Since Speed (V) = Distance (D)/Time (t)
2). Then t=D/V ( transpose)
3). So t= 2220/555
t= 4 hours
The plane flew for four hours
