8x + 5
Step-by-step explanation:
By adding
2x + 6 + 6x -1
8x + 5
1 km = 1,000 m....so 322km = 322,000 m
so the falcon can fly 322,000 m per hr
Answer:

they're all like terms so we just add and subtract
Answer:
x=5/2 + a/2, y= 5/2 - a/2
Step-by-step explanation:
We can solve this system using addition of the equations
x+y=5
<u>x-y=a</u>
2x =(5+a)
x=(5+a)/2= 5/2 +a/2
x=5/2 +a/2
x-y=a
y = x - a , x=5/2 + a/2
y= 5/2 + a/2-a
y= 5/2 - a/2
