Answer:
-7 > x
Step-by-step explanation:
first we expand the brackets so it will be -3x -6>-69-12x
then we can convert the > to = so it will be :
-3x -6=-69-12x
we can now try to solve the equation for x so :
-3x -6= -69-12x
-6 = -69-9x
63 =-9x
7 = -x
-7 = x
we can then change the symbols back so it will be:
-7 > x
Answer:
a) $1056.33 b) 23 years
Step-by-step explanation:
a) 10000(1+1.85/100)^3=10565.33 (2d.p.)
b) let x be the no. of years
15000 = 10000(1+1.85/100)^x
1.5 = 1.0185^x
ln both sides
ln 1.5 = x ln 1.0185
x = ln 1.5/ln 1.0185
=22.11
=23 years (rounded up)
