Answer:
The answer is
.
Step-by-step explanation:
Given:
18 2/5 - n = -10 1/3.
Now, to solve the equation:

Converting the mixed fractions to improper:
⇒
Moving the numbers on one side and variable to the other:
⇒
Now, solving the factions:
⇒
⇒
⇒
⇒
Therefore, the answer is
.
Find Angle B: B = 180 - (82+55) = 43. Then apply the law of sines:
b 8 cm
--------- = ----------
sin 43 sin 55
(sin 43)(8 cm)
Solving for b, we get b = ------------------- = 6.66, or 6.7 (cm, to the nearest tenth).
sin 55

To solve this problem you must apply the proccedure shown below:
1. You must make a system of equation by using the information given in the problem above. Then, let's call:
: The number of computers sold.
: The number of hard drives sold.
2. Therefore, you have the following system of equations:

2. Solve for
in the first equation and substitute it into the second equation:

3. Solve for
:

4. Substitute the value of
into the first equation to calculate
:

Therefore, the answer is: The store sold
computers and
hard drives.
(0.4n)(16n) = (0.4)(16)(n)(n) = 6.4n²
Answer: 6.4n²
