Kareem has 26 2 3 feet of vinyl siding and 33 3 4 feet of wooden siding. he cuts the vinyl siding into 3 1 3 feet long strips and the wooden siding into 2 1 4 feet long strips. how many more strips of wood siding than vinyl siding does he have
Kareem has 7 more strips of wood siding than vinyl siding.
What is a siding?
A siding is a brief railroad track with one or both ends opening into the main track, used to switch one of two meeting trains until the other has passed. Or a siding is any of a number of different forms of weatherproof face for frame buildings, made up of individual sections fastened together as shingles, plain or shaped boards, various sheet metal components, or other composition materials.
Number of vinyl siding strips = 2623/313 = 8.38 ≈ 8 strips
Number of wooden siding strips = 3334/214 = 15.57 ≈ 15 strips
Therefore, extra strips of wooden siding = 15 - 8 = 7 strips

What is arithmetic sequence?See the pattern
2-0 = 2

By this we conclude that next term is not 8.
An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.
Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.
An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

Solve each system.
7x + 2y = -8 , 8y = 4x
After solving each system, 7x + 2y = -8, 8y = 4x , the values of x and y are calculated to be -1 and -1/2 respectively.
The given equations, 7x + 2y = -8, and 8y = 4x, are considered to be linear equations as the highest power of the variables in these equations is one.
By rearranging the second equation, the value of x can be found to be,
8y = 4x
x = 8y / 4
x = 2y
Putting the calculated value of x in the second equation,
7x + 2y = -8
7(2y) + 2y = -8
14y + 2y = -8
16y = -8
y = -8/16
y = -1/2
To solve for x, put the calculated value of y in the first equation,
7x + 2y = -8
7x + 2(-1/2) = -8
7x - 1 = -8
7x = -8 + 1
7x = -7
x = -7/7
x = -1
Thus the values of x and y in these systems are calculated to be -1 and -1/2 respectively.

A fraction (from Latin: fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction consists of a numerator, displayed above a line (or before a slash like 1⁄2), and a non-zero denominator, displayed below (or after) that line. Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals.
In positive common fractions, the numerator and denominator are natural numbers. The numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. The denominator cannot be zero, because zero parts can never make up a whole. For example, in the fraction 3/4, the numerator 3 indicates that the fraction represents 3 equal parts, and the denominator 4 indicates that 4 parts make up a whole. The picture to the right illustrates 3/4 of a cake.

In the given statement is
To find the midpoint of the line segment joining the pair of points
G(1,-1,6) and H(1/5,-2/5, 2)
Midpoint:
The coordinates of the midpoint of a line segment are the average of the coordinates of the end points.
m = (A +B)/2
If we are given three points and we wish to find the midpoint of those points, we need to use the midpoint formula m =([tex]\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} , \frac{z_{1}+z_{2} }{2}[/tex] )
where:
(x1 , y1 ,z1) are the coordinates of the first point:
(x2 , y2 , z2) are the coordinates of the second point:
Now, We are given the three points G(1,-1,6) and H(1/5,-2/5, 2)
Solving for the midpoint , we have,
m = ([tex]\frac{1+\frac{1}{5} }{2} , \frac{-1+(\frac{-2}{5} )}{2} , \frac{6+2}{2}[/tex])
