Answer:
x + (x-73) + 67 = 180
x + x - 73 +67 = 180
2x - 6 = 180
2x = 180 + 6
x = 186 / 2
x = 93
Step-by-step explanation:
x-73+x+67=180(sum of angles in a triangle )
2x-6=180
2x=180+6=186
x=186/2
x=93

The length of a rectangle is five times its width.
If the perimeter of the rectangle is 72 cm, find its area.
Answer:
180 cm²
Step-by-step explanation:
x = length
y = width
perimeter of a rectangle is the sum of all sides, so, 2×length plus 2×width.
x = 5y
72 = 2x + 2y
using the first equation as substitute in the second equation
72 = 2×(5y) + 2y = 10y + 2y = 12y
y = 6 cm
x = 5y = 5×6 = 30 cm
area = x × y = 30 × 6 = 180 cm²

and b =
7/10
The answer is
(Simplify your answer.)
a= 9/11 and b=7/10
now,
ab = (9/11)×(7/10)

the value of ab is 63/110 when a = 9/11 and b = 7/10
What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given, the values of a and b are 9/11 and 7/10 respectively
thus,
ab = 9/11 * 7/10
simplifying it
ab = 63/110
Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10

c. When measuring the dimensions of a room a carpenter uses a tape measure that only displays a number of feet, L, on the metal tape.
(The carpenter's tape measure does not display inches).
i. Write an expression to determine the length of the room in yards.
Preview
ii. Write an expression to determine the length of the room in units of 3 feet (yards).
Preview
iii. Write an expression to determine how many times as long the room is than 3 feet.
Preview
The dimension of a room is the length and width of the room.
The length of the room in yard is L/3An expression for the length of the room in unit of 3ft is 3LThe room is longer than 3 feet, in L timesFrom the question, we have:
[tex]L \to[/tex] Number of feet
(a) An expression for the length of the room in yards
In standard unit of conversion
[tex]1ft = \frac{1}{3} yd[/tex]
Multiply both sides by L:
[tex]L \times 1ft = L \times \frac{1}{3} yd[/tex]
[tex]L\ ft = \frac{L}{3} yd[/tex]
Hence, the length of the room in yard is L/3
(b) An expression for the length of the room in unit of 3ft
In (a), we have:
[tex]L \to[/tex] Number of feet
To calculate the length in units of 3 feet, we simply multiply L by 3
[tex]Unit = 3 \times L[/tex]
[tex]Unit = 3L[/tex]
An expression for the length of the room in unit of 3ft is 3L
(c) How many times longer the room is, than 3ft.
In (b), we have:
[tex]Unit = 3L[/tex]
The number of times (n) the room is longer than 3 ft is:
[tex]n = Unit \div 3[/tex]
[tex]n = 3L \div 3[/tex]
[tex]n = L[/tex]
The room is longer than 3 feet, in L times

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n" ways; then the two events in succession can occur in m × n ways.
Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.
Pencil = 21
Pencil holder = 3
Therefore, we will do as 21 divided by 3
21/3 = 7
Hence, there are 7 pencils in each pencil holder.

What is a rational function?
In mathematics, a rational function is any function that can be described by using a rational fraction, which is an algebraic fraction such that each the numerator and the denominator are polynomials. The coefficients of the polynomials need no longer be rational numbers; they'll be taken in any field k.
A rational function is one that can be written as a polynomial divided by a polynomial. for the reason that polynomials are defined everywhere, the domain of a rational feature is the set of all numbers except the zeros of the denominator. example 1. f(x) = x / (x - 3). The denominator has only one 0, x = 3.
