283.5
So you multiply 6.75 by 21 stools to find the total number of meters. Then you multiply that by 2.
Answer:
n = -8
Step-by-step explanation:
5+n/8=4
Subtract 5 from each side
5-5+n/8=4-5
n/8 = -1
Multiply each side by 8
n/8 * 8 = -1 *8
n = -8

Answer: $2400</h3>
========================================================
Explanation:
x = Mason's salary in dollars for that month
x/6 = one-sixth of his salary
x/6+800 = total amount spent (the x/6 dollars and $800 combined)
In total, he spent half his salary. This means he spent x/2 dollars for the month overall.
Set the two items equal to one another. Solve for x.
x/6 + 800 = x/2
6(x/6 + 800) = 6*(x/2) ... see note at the bottom of the page
x+4800 = 3x
4800 = 3x-x
4800 = 2x
2x = 4800
x = 4800/2
x = 2400
His monthly salary is $2400
1/6 of this is (1/6)*2400 = 2400/6 = 400 dollars. Add on the $800 he also spent to get a total of 400+800 = 1200 dollars spent, which is exactly one half of the $2400. The answer is confirmed.

Note: I multiplied both sides by 6 to clear out the fractions. The value 6 is the LCD in this case.
The solution for this problem is just simple. It tells you to find the area in square feet. Thus, convert the units to feet first. The conversion you need to know are: 12 in = 1 ft and 3 ft = 1 yard.
Width = 42 in * 1 ft/12 in = 3.5 ft
Length = 10 yards * 3 ft/1 yard = 30 ft
Area = Length*Width = 30*3.5
<em>Area = 105 ft²</em>
