Answer:
Bonds: $42,000
Certificates of deposit: $41,000
Step-by-step explanation:
Total invested = Amount in bonds + Amount in CDs
  
Amount in bonds = Amount in CDs + 1000
  
Let the amount in bonds = B and the amount in CDs = C
  
  
1. 83,000 = B + C
  
2. B = C+1000
  
Since the above expression (#2) defines B, you can substitute it for the B in the first equation (#1).
  
83,000 = C + 1000 + C
  
Now, you can solve for C.
  
83,000 = 2C + 1000
82,000 = 2C
41,000 = C
  
You know that the amount invested in bonds is $1000 greater than the amount invested in CDs, so add $1000 to C and you find B, $42,000.

Answer:
Disagreee
Step-by-step explanation:
it has 6 sides so take 360/6 and you'll get 60, so it has to be rotated 60deg for it to be carried onto itself.
