<span>We have this equation:
</span>

and we need to find the value of x.
First of all, we multiply the whole equation for 1/2, so our goal is to isolate x, therefore:
Next step we must do is to apply <span>logarithms:
</span>

Next, we have to apply identities and then to solve the equation:




Finally, we have the value of x which was our goal. This is the answer for the question above:
Answer:
4. 988 people
5. a. 7 quarters
b. 6 quarters 2 dimes 1 nickel
c. 5 quarters 5 dimes
d. 4 quarters 7 dimes 1 nickel
1. $65.65, $5.05
2. $7.70, $15.40
3. a. 7 quarters
b. 6 quarters 2 dimes 1 nickel
c. 5 quarters 5 dimes
d. 4 quarters 7 dimes 1 nickel
4. 31 bags
5. $30, $4.50
Step-by-step explanation:
4. take value times percent.
5. think coins
1. find difference then divide by number of days (13)
2. multiply by 1/3 then find difference.
3. think coins
4. find area then divide by 200
5. just break the problem down and go quarter by quarter.
Last year won the lions 16 games last year and into this year the Lions won 20 games.
as the percentage increase is:
20/16
(20/4) / (16/4)
5/4
<span>
1.25 (125%)</span>
