18 2/5 - n = -10 1/3

Wewaii [24]

Answer:

The answer is $n=28\frac{11}{15}$ .

Step-by-step explanation:

Given:

18 2/5 - n = -10 1/3.

Now, to solve the equation:

$18\frac{2}{5} - n = -10 \frac{1}{3}$

Converting the mixed fractions to improper:

⇒ $\frac{92}{5} -n=-\frac{31}{3}$

Moving the numbers on one side and variable to the other:

⇒ $\frac{92}{5} +\frac{31}{3}=n$

Now, solving the factions:

⇒ $\frac{92\times 3+31\times 5}{15}=n$

⇒ $\frac{276+155}{15}=n$

⇒ $\frac{431}{15}=n$

⇒ $28\frac{11}{15}=n$

Therefore, the answer is $n=28\frac{11}{15}$ .

Find b. Round to the nearest tenth.

Svetradugi [14.3K]

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).

One week a computer store sold a total of 36 computers and external hard drives. the revenue from these sales was $30875 . if c

melamori03 [73]

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:

$x$ : The number of computers sold.

$y$ : The number of hard drives sold.

2. Therefore, you have the following system of equations:

$\left \{ {{x+y=36} \atop {1180x+125y=30875}} \right.$

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

$x=36-y\\ 1180(36-y)+125y=30875$

3. Solve for $y$ :

$42480-1180y+125y=30875\\ y=11$

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

$x+11=36\\ x=25$

Therefore, the answer is: The store sold $25$ computers and $11$ hard drives.
