Simplify by combining like terms. -(3 z-5)+z
The simplification by combining like terms of -(3z -5) + z is -2z + 5.
According to the given question.
We have an expression -(3z -5) + z.
As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same. when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.
Since, we have to combine the like terms of the given expression -(3z - 5) +z.
Here -3z and z both are the like terms.
So, we subtract coeffcients of z to simplify the given expression.
Therefore, the simplification of the expression -(3z - 5) +z is given by
-(3z - 5) + z
= -3z + 5 + z
= -3z + z + 5
= -2z + 5
Hence, the simplification by combining like terms of -(3z - 5) + z is -2z + 5.

Find the measure of each numbered angle. (Lesson 4-2)
m ∠ 6
The measurement of angle ∠2 is 67.50°.
What exactly do we mean by an angle?In Euclidean geometry, an angle is a figure formed by two rays called the sides of the angle that share a common endpoint called the vertex of the angle.Angles formed by two rays are located in the plane in which the rays are located.When two planes intersect, angles are formed.These are referred to as dihedral angles.So,
An octagon has 8 sides.Sum of interior angles = 180° x (n-2) = 180° x (8-2) = 180° x 6 = 1,080°1,080° ÷ 8 sides = 135° interior angle.Angle 2 = 135° / 2 = 67.50°Therefore, ∠2 is 67.50°.

A stop sign in the shape of a regular octagon is inscribed in a circle. Find following measure.
m < LRQ
The term "intercepted arc" refers to an arc that is "cut off" or "lies between" the specified angle's sides.
The measure of < LRQ is 112.5.
What is an Intercepted Arc?
The term "intercepted arc" refers to an arc that is "cut off" or "lies between" the specified angle's sides.
An arc is a segment of a circle's circumference. An intercepted arc is thus one formed when one or two different chords or line segments cut across a circle and meet at a common point known as a vertex.
If an angle is inscribed in a circle, then the measure of the angle equals one half the measure of its intercepted arc.
So, [tex]$m \angle L R Q=\frac{1}{2}(m \overparen{L N Q})$[/tex]
The sum of the measures of the central angles of a circle with no interior points in common is 360 .
Here, 360 is divided into 8 equal arcs and each arc measures
360/ 8 = 45.
Then, m LNQ = m LM + m MN + m NO + m OP + m PQ = 5(45) = 225.
[tex]$m \angle L R Q=\frac{1}{2}(225)=112.5$[/tex].
Therefore, the measure of < LRQ is 112.5.

A meeting room is set up with 16 rows of seats. The number of seats in a row increases by two with each successive row. The first row has 12 seats. What is the total number of seats?
a. How can you find the number of seats in each row using an explicit formula?
The most commonly used explicit of an arithmetic sequence is given as,
an = a + (n - 1) d
Each term in the sequence can easily be solved/computed without knowing the other terms in the sequence. Now by using the given information, we can say that,
2nd row seat = 12+ 1x2
3rd row seat = 12 + 2 x2
nth seat = 12 + (n-1) x 2
16th row seat = 12 + (16–1) x2 = 42
Since the number of seats is increasing at a constant rate, we can calculate the average number of seats in each row by taking the average of the first and last rows
Average number of seats per row = (12 +42)/2= 27
So total seats = average per row x number of rows
= 27 x 16 = 432.

Simplify the expression.
16-12 / 15-11
The simplified expression for (16-12 / 15-11) is 1 .
The given expression is,
( 16-12 / 15-11 )
First we need to solve the numerator which is (16-12) and on simplifying the numerator we can write,
Numerator = ( 16 - 12 ) = 4 equation 1
Similarly, now we can proceed to solve the denominator which is (15 - 11) and on simplifying the denominator we write,
Denominator = (15 - 11) = 4 equation 2
Now we can substitute the value of numerator and the denominator from equation 1 and equation 2 in the given expression ( 16-12 / 15-11 ) as,
(Numerator / Denominator) = (16-12 / 15-11) = (4/4) = 1

Kendra buys 5 yards of yellow fabric and 8yards of purple fabric The yellow
costs $2 more per yard than the purple fabric,
She pays a total of 62.80 what
would be the combined cost of 2 yards of yellow and yards of purple
fabric?
The combined cost of 2 yards of yellow and 1 yard of purple fabric is $17.69.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Length of yellow fabric = 5 yards
Length of purple fabric = 8 yards
Let x be the cost of per yard purple fabric.
Then, cost of per yard yellow fabric = 2 + x
Now since, Total amount paid is $62.80
Therefore,
5(2 + x) + 8x = 62.8
expanding the brackets we get,
10 + 5x + 8x = 62.8
Solving we get,
10 + 12x = 62.8
or, 12x = 52.8
⇒ x = 62.8/12
⇒ x = $5.23
Thus the cost of per yard purple fabric = $5.23
Similarly, cost of per yard yellow fabric = 2 + 5.23 = $7.23
Thus, combined cost of 2 yards of yellow and 1 yard of purple
fabric = 2*$5.23 + $7.23
= $10.46 + $7.23
= $17.69
Thus, the combined cost of 2 yards of yellow and 1 yard of purple fabric is $17.69

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such as printing). There are two production methods it could use. With one method, the one-time fixed costs will total $44,714, and the variable costs will be $11.50 per book. With the other method, the one-time fixed costs will total $17,174, and the variable costs will be $20 per book. For how many books produced will the costs from the two methods be the same?
The number of books published by a small publishing company is 3240.
Given that, a small publishing company is planning to publish a new book. The production costs will include one-time fixed costs and variable costs.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of books be x.
With one method, the one-time fixed costs will total $44,714, and the variable costs will be $11.50 per book.
That is, 44,714+11.50x
With the other method, the one-time fixed costs will total $17,174, and the variable costs will be $20 per book.
That is, 17,174+20x
Now, the number of books produced will the costs from the two methods be the same.
So, 44,714+11.50x=17,174+20x
⇒ 44,714-17,174=20x-11.50x
⇒ 8.5x = 27540
⇒ x=3,240
Therefore, the number of books published by a small publishing company is 3240.

The solution of the simultaneous equation is given by (-7 , 4) .
A pair of simultaneous equations is the most common representation of a pair of straight lines in the cartesian plane.
For solving a pair of simultaneous equation we can use various procedures such as the matrix method, substitution or the method of elimination.
The given pair of simultaneous equation is given as:
x=−2y+1
3x+8y=11
Let us solve the equations by the method of substitution:
From the first equation we take the value of x and put it in the second equation:
3x + 8y = 11
or, 3 ( -2y + 1 ) + 8y = 11
or, -6y +3 +8y = 11
or, 2y + 3 = 11
or, 2y = 8
or, y = 4
Substituting the value of y as 4 in the first equation we get:
x = − 2y + 1
or, x = - 2 × 4 +1
or, x = -8 +1

Negative integers are always less than 0 and positive integers. More the magnitude (numerical value) of a negative integer, lesser is that number.Hence the order of negativeintegers will be -24 < -2 < -7/4. 1/2 is 0.5 and root 5 is around 2.236. Hence, 1/2 < √5.
