Answer:
Step-by-step explanation:
5 times 2 equales 10 divided by 40 eqauls 4 times 2 equals 8
Answer:
is the logarithmic equation which is equivalent to
.
Step-by-step explanation:
According to the laws of logarithms
,where b=base ,n,x all are positive
It can be written in exponential form such as

Now in the given question x=9 ,b=3 and n=2 such that it will equals to

Hence the logarithmic equation for
is
.
Do 24/30, which is 0.8. Convert this to a percentage
==============> 80%
X+10=15
Isolate x by subtracting 10 from both sides
x+10-10=15-10
x=5
Final answer: B
Check by plugging the value in
5+10=15
True
