Answer:
x = [tex]\frac{6}{4+a-2b}[/tex]
Step-by-step explanation:
Given
4x + ax = 2(bx + 3) ← distribute parenthesis
4x + ax = 2bx + 6 ( subtract 2bx from both sides )
4x + ax - 2bx = 6 ← factor out x from each term on the left side
x(4 + a - 2b) = 6 ← divide both sides by (4 + a - 2b)
x = [tex]\frac{6}{4+a-2b}[/tex]

In April, Phillipa rode 13 . 5 + 8 . 7 + 11 . 1 miles on her bicycle. In March, she rode ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 miles, and in May, she rode 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) miles. Determine the month when she rode the most and the month when she rode the least. How many times farther did she ride in the month when she rode the most than in the month when she rode the least?
Answer:
Phillipa rode the most in May and rode the least in March.
Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March
Step-by-step explanation:
Given:
In April, Phillipa rode 13 . 5 + 8 . 7 + 11 . 1 miles on her bicycle. In March, she rode ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 miles, and in May, she rode 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) miles.
To find: the month when she rode the most and the month when she rode the least
Solution:
Distance travelled by Phillipa on her cycle in April = 13 . 5 + 8 . 7 + 11 . 1 = 65 + 56 + 11 = 132 miles
Distance travelled by Phillipa on her cycle in March = ( 13 . 5 + 8 . 7 + 11 . 1 ) ÷ 2 = [tex]\frac{132}{2}=66[/tex] miles
Distance travelled by Phillipa on her cycle in May = 4 × ( 13 . 5 + 8 . 7 + 11 . 1 ) = 4 × 132 = 528 miles
So, she rode the most in May and rode the least in March
Distance travelled by Phillipa on her cycle in May = 8 × Distance travelled by Phillipa on her cycle in March

Step-by-step explanation:
the number of sides of a regular polygon whose interior angle is 140
Answer:
9 sides
Step-by-step explanation:
Two methods and the same answer = 9 sides
Method 1: Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
Method 2: Since the exterior angle 140 degrees, The sum of the interior angles = (2n - 4)* right angles. So 140n =(2n - 4)* right angles, or
140n =(2n - 4)*90, or
140n = 180n - 360, or
40n = 360, or
n = 9 sides.
Hence the number of sides is 9 sides.
Answer:
9
Step-by-step explanation:
The sum of the interior angle and the exterior angle = 180°
Thus the exterior angle of the polygon = 180° - 140° = 40°
The sum of the exterior angles of a polygon = 360°, thus
number of sides = 360° ÷ 40° = 9

which classification best represents a triangle with a side lengths 6 cm,10 cm, and 12 cm ?
Answer:
It would be an obtuse scalene triangle.
EDITED TO ADD:
When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle
if sum < 3rd side² Obtuse Triangle
6^2 = 36

Ms. Ziolkowski asks her class to write the correct trigonometric function for the triangle shown below.
Two students get into an argument about the correct answer.
Rhianna states that the correct trig function is tan A = 3/4. Christopher insists that the correct trig function is tan C = 4/3. Who is correct? In writing your response, be sure to include the terms opposite side, adjacent side, tangent ratio, and reference angle. Be sure to restate the question and explain your position with at least four sentences.
Answer:
They are both correct
Step-by-step explanation:
tan A = opposite / adjacent = 3/4 >>> A= 36.9 deg
tan C = opposite / adjacent = 4/3 >>> C= 53.1 deg
cheak:
<B+ <A + <C = 180 deg
90 + 36.9 + 53.1 = 180
180 = 180
Answer:
Botn are correct
Step-by-step explanation:
Tan ratio can be obtained by opposite/adjacent
Both students are correct. They have different values only because they have taken different reference angles
Rhianna has taken angle A as the reference angle,
So tanA = opposite/adjacent = BC/AB
tanA = 3/4
Christopher has taken angle C as the reference angle,
So tanC = opposite/adjacent = AB/BC
tanC = 4/3

a secant and tangent are drawn to a circle from a common exterior point. If the length is 14 inches and the length of the external segment of the secant is 4 inches, then it which of the following is the length,in inches, of the internal segment of the secant?
Answer:
Correct option: (3) 45
Step-by-step explanation:
Let's call the length of the tangent 'T', the length of the external segment 'E' and the length of the internal segment 'A'.
If we have a secant and a tangent to a circle, we can use the following property:
T^2 = E * (A + E)
If the tangent is 14 inches and the external segment is 4 inches, we have that:
14^2 = 4 * (A + 4)
196 = 4A + 16
4A = 180
A = 45
Correct option: (3)

Tim tiene 39 pares de audífonos y 13 reproductores de música. Tim quiere vender todos los audífonos y los reproductores de música en paquetes idénticos. ¿Cuál es el mayor número de paquetes que Tim puede hacer?
Answer: 13 packages.
Step-by-step explanation:
This can be translated to:
Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical packages. What is the largest number of packages that Tim can do?
To solve this we must find the largest common factor between 39 and 13.
to do this, we divide the smaller number by different integers, and see if the result also divides the larger number into an integer.
13/1 =13 and 39/13 = 3
So 13 is the largest common factor.
This means that we can make 13 packages, each with:
39/13= 3 headphones
13/13 = 1 music players
What is the slope-intercept equation of the line below?
Answer:
The slope-intercept form:
[tex]y = -3x +4[/tex]
Step-by-step explanation:
-To get the slope-intercept equation, you first need to find the slope by using this equation [tex]m = \frac{rise}{run}[/tex] (starting counting from the first point, to the second point) in order to get the slope. After you have the slope, you need to find the y-intercept ( y-intercept is where the line crosses the y axis of the graph, basically). So, to find that, you need look for the point that only crosses the y axis to get the y-intercept. After you have both the slope and y-intercept, you put it in slope-intercept form:
The two points I found from the following graph are:
[tex]( 1, 1)[/tex] and [tex](2, -2)[/tex]
Trick: Since the line of the graph shows that it is down (not up), Start counting down from point [tex]( 1, 1)[/tex] to point [tex](2, -2)[/tex]. Then, find the y-intercept:
[tex]m = \frac{-3}{1} = -3[/tex]
[tex]b = 4[/tex]
Use it to create a slope-intercept form:
[tex]y = mx +b[/tex] (where [tex]m[/tex] represents the slope and [tex]b[/tex] represents the y-intercept)
[tex]y = -3x +4[/tex]
So, therefore the slope-intercept form is [tex]y = -3x +4[/tex] .
