Answer:
Ex. 2:1 = 4:2 or 8:4
~Hope this helps!!
x + y = 9
x = 9 - y
2x - y = 0
2(9 - y) - y = 0
18 - 2y - y = 0
-3y = -18
y = 6
x = 9 - 6
x = 3
y = 23, -31
Step-by-step explanation
ttyl
principle= 6000
time =9 years
rate = 7%
so,
compound interest = p((1+r/100)^t. -1)
= 6000((1+0.07)^9 -1)
=6000(1.84-1)
=6000*0.84
=5040
