ANSWER
EXPLANATION
First equation:
Second equation:
Let us equate the two equations and solve for x.
This implies that;
Group similar terms to obtain:
Simplify:
Divide both sides by 3
Put x=-2 into any of the equations.
I will put x=-2 into the first equation:
This implies that,

The volume of a figure is the quantity of three-dimensional space enclosed by a closed surface, or simpler the number of cubes required to fill it completely.
The basic unit of volume in the metric system is the liter (l).There are 1000 liters per cubic meter.
Howeever, the unit of measure that would be appropriate for the volume of a sphere with a radius of 2 meters is cubic meters. Correct answer: C
Using the mean concept, the average collection for a student in this school was of $16.13.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
The number of students is given as follows:
82 + 74 + 96 + 99 = 351.
The sum is:
82 x 26.75 + 74 x 12.25 + 96 x 15.50 + 99 x 10.85 = $5662.15
Hence the mean is:
M = $5662.15/351 = $16.13.
