Answer:
no. it isn't necessary.
Step-by-step explanation:
there are some cases where adding two repeating decimals results in a sum which does not have a repeating decimal. For example,
1 over 3
+
2 over 3
=
3 over 3
=1
. Thus, the sum of two repeating decimals is not always a repeating decimal.
We have that
<span>Log3 a/3
</span>Rewrite log3(a/3) using the change of base <span>formula
we know that
</span>The change of base rule can be used if a and b are greater than 0 and not equal to 1, and x is greater than 0<span>.
</span>so
loga(x)=<span>logb(x)/<span>logb<span>(a)
</span></span></span>Substitute in values for the variables in the change of base <span>formula
</span>
in this problem
b=10
a=3
x=a/3
log3(a/3)=[log (a/3)]/[log (3)]
the answer is
[log (a/3)]/[log (3)]
Answer:
➩ 2,250 envelopes.
Step-by-step explanation:
Given that, Nicole buys 125 envelopes per box for her home office.
Therefore, She will have 18*125 envelopes in all
So, 18*125 is 2,250 envelopes
Let "x" represent the age of Brian.
Andrew is elder than Brian by 2 years, we can symbolize his age as "x+2"
Frank is twice as old as Andrew, we can symbolize his age as "2(x+2)"
Sarah has half the age of Brian's, we can symbolize her age as "x/2"
Frank ans Sarah's ages differ by 40 years, we can symbolize this as:
Solve the term is parenthesis
x=24 years
Andrew's age is
Andrew is 26 years old
