Answer:
The first coin will be worth $137.16 more than the second coin.
Step-by-step explanation:
Interest formula = i = prt
For coin #1:
p = 1270
r = 0.061
t = 18
i = (1270)(0.061)(18)
The first coin will be worth $2664.46 after 18 years.
For coin #2:
p = 1270
r = 0.055
t = 18
i = (1270)(0.055)(18)
The second coin will be worth $2527.30 after 18 years.
Subtract the value of coin #2 from coin #1.
2664.46 - 2527.30 = 137.16
In conclusion, the first coin will be worth $137.16 more than the second coin after 18 years.
Answer: X= -15
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
4/6 can reduce to 2/3. (divide each by 2)
14/21 can reduce to 2/3 by dividing the nume/denominator by 7.
in this case, they are proportional.
-15x -8y=-27 Thas the answer
