One solution.. what you're describing is two lines that intersect at the common y intercept. This will be the only point that satisfies both equations in the system.
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:
600 ft per side
Step-by-step explanation:
1 in = 200 feet
12 in = 1 foot
12 in * 200 ft= 2400 ft
2400/4 = 600 ft per side
13+2=15+1=16 that is the answer
