In the figure below, ray MP and ray MQ both intersect line LN.

Answers

Answer:

x = 20°

Step-by-step explanation:

Lines and Angles

Rays PM and MQ divide the straight-line LN angle of 180° into three angles: 45°, 6x-5, and x.

Thus, we have:

45 + 6x - 5 + x = 180

Simplifying:

40 + 7x = 180

Subtracting 40:

7x = 180 - 40

7x = 140

Dividing by 7:

x = 140/7 = 20

x = 20°

10 + 4a = a -23 i need to solve for a please help

Answers

Answer:

a = -11

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

10 + 4a = a - 23

Step 2: Solve for a

Subtract a on both sides:                    10 + 3a = -23Isolate a term:                                      3a = -33Isolate a:                                               a = -11

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Substitute in a:                    10 + 4(-11) = -11 - 23Multiply:                               10 - 44 = -11 - 23Subtract:                               -34 = -34

Here we see that -34 does indeed equal -34.

∴ a = -11 is the solution to the equation.

For solving such problems we must have a glance at BODMAS rule .

⠀⠀⠀⠀

Firstly , putting all the variables at left and putting all the constants at right

⠀⠀⠀⠀

4a - a = - 23 - 10

⠀⠀⠀⠀

Secondly , solving the variable side

⠀⠀⠀⠀

3a = -23 - 10

⠀⠀⠀⠀

Now , solving the constant side

⠀⠀⠀⠀

3a = - 33

⠀⠀⠀⠀

Thirdly isolating the variable

⠀⠀⠀⠀

a = -33 / 3

a = - 11

Which graph shows a proportional relationship that passes through the point (2, 1)?
A.
B.
C.

Answers

The graph that shows a proportional relationship that passes through the point (2, 1) is Graph A.

Equation of a line

A line is defined as a shortest distance between two points. In order to determine the graph that shows a proportional relationship that passes through the point (2, 1), we will need to multiply the coordinate by a scale factor and determine whether the point is on the line.

Using a factor of 2;

New coordinate = 2(2, 1)

New coordinate = (4, 2)

From the given graph, you can see that the only graph that has the coordinate point (4, 2) is the Graph A.

Write y= -1(x-4.5)^2 + 15.25 in standered form

Answers

Given:

The equation is

[tex]y=-1(x-4.5)^2+15.25[/tex]

To find:

The standard form of the given equation.

Solution:

We have,

[tex]y=-1(x-4.5)^2+15.25[/tex]

It is a quadratic equation.

The standard form of a quadratic equation is [tex]y=ax^2+bx+c[/tex]. So, we need to write the given equation in this form.

[tex]y=-(x-4.5)^2+15.25[/tex]

[tex]y=-[x^2-2(x)(4.5)+(-4.5)^2]+15.25[/tex]         [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]

[tex]y=-[x^2-9x+20.25]+15.25[/tex]

[tex]y=-x^2+9x-20.25+15.25[/tex]

[tex]y=-x^2+9x-5[/tex]

Therefore, the required equation in standard form is [tex]y=-x^2+9x-5[/tex].

Nevaeh's car used 11 gallons to travel 352 miles. At what rate does the car use gas, in
miles per gallon?

Answers

Answer:

32

Step-by-step explanation:

divide 352 by 11

The required rate for Nevaeh's car uses 32 miles per gallon of gas.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

The required rate of car use gas is the ratio of the total distance traveled by car to the number of used gallons for the car to reach its destination.

Here total distance traveled by car = 352 miles

And the number of used gallons = 11

the car uses gas = 352 miles / 11 gallons

the car uses gas = 32 miles per gallon

Therefore, the required rate for his car uses 32 miles per gallon of gas.

Elena and Max used to rectangular wooden boards to make a set for the school play one board was 6 ft long and the other was 5 and 1/2 ft long the two boards had equal width the total area of the set was 60 and 3/8 square feet what was the width

Answers

Answer:the width is 5 1/4 ft

Step-by-step explanation:

Step 1

The area of a rectangle is given as  Length x width

Therefore the area of the rectangular board = Length x width

The length of the first board =6ft  

The length of the second board =5 1/2 ft  (5.5ft) with both having a total area of 60 3/8 (60.375ft²). To find the width of the boards since both have equal width, we use the equation

Length x width of board A +  Length x width of board B= area of board A and Board B

6w + 5.5w =60.375

Step 2---- Solving the equation

 6w + 5.5w =60.375

       11.5w = 60.375

               w = 60.375/11.5

                  w= 5.25

Therefore  the width of the two boards are  5.25 ft / 5 and 1/4 ft each

The table below shows the number of pencils and pens three friends have in their backpacks.

Who has a greater ratio of pencils to pens?
A. Lydia
B . Angel
C . Elizabeth

Answers

Answer:

Angel has a greater ratio of pencils to pens.

i.e. Angle's pencils to pens = 3 / 2 or 63/42

Thus, option (B) is true.

Step-by-step explanation:

Considering the table

Lydia's Number of Pencils = 10

Lydia's Number of Pens = 7

Lydia's Pencils to Pens ratio = 10/7

Angel's Number of Pencils = 9

Angel's Number of Pens = 6

Angels's Pencils to Pens ratio = 9/6 = 3 / 2

Elizabeth's Number of Pencils = 12

Elizabeth's Number of Pens = 9

Elizabeth's Pencils to Pens ratio = 12/9 = 4 / 3

So, We get the inputs ratios such as:

Lydia's ratio:  Angels's ratio: Elizabeth's ratio

      10/7      :         3 / 2         :        4 / 3

As the least common denominator (LCD) is: 42

Rewriting as equivalent fractions with the LCD:

10/7            :         3 / 2         :        4 / 3

60 / 42       :        63/42       :       56/42

Sorting from least to greatest:

Sorting this table by the numerators of the equivalent fractions in order from least to greatest:

Elizabeth's ratio       :         Lydia's ratio       :    Angels's ratio:  

4/3                             :         10 /7                  :        3 / 2

56/42                        :          60 / 42             :         63/42

Therefore, Angel has a greater ratio of pencils to pens.

i.e. Angle's pencils to pens = 3 / 2 or 63/42

Thus, option (B) is true.
