Answer:
x = 10
Step-by-step explanation:
Isolate the radical, then raise each side of the equation to the power of its index.
Answer 5
Step-by-step explanation:
6/12=.5
.5*10=5
2/7x-1/7x=100
subtract the 2/7x and the 1/7x
so it would be
1/7x=100
multiply 1/7 on both sides
so
x=100 times 1/7
solve
x=100/7
x=14 2/7
Answer:
t=16.2 years
Step-by-step explanation:
A=p(1+r/n)^nt
A=$20100
P=$6500
r=7%=0.07
n=4
t=?
t=ln(A/P)/n {ln(1+r/n)}
=ln(20100/6500) / 4{ln(1+0.07/4)}
=ln(3.0923)/4{ln(1+0.0175)}
=ln(3.0923)/4{ln(1.0175)}
=1.1289/4(0.0174)
=1.1289/0.0696
=16.23
To the nearest tenth
t=16.2 years
