1/3 x + 1 = 5/6 x - 3
Answer:
x=8
Step-by-step explanation:
Step 1: Subtract 5/6x from both sides.
1/3x+1−5/6x=5/6x−3−5/6x
−1/2x+1=−3
Step 2: Subtract 1 from both sides.
−1/2x+1−1=−3−1
−1/2x=−4
Step 3: Multiply both sides by 2/(-1).
(2/−1)*(−1/2x)=(2/−1)*(−4)
x=8

How would I solve this problem?
Answer:
n= 4
Step-by-step explanation:
[tex]a^{m}*a^{n}=a^{m+n}\\\\(a^{m})^{n}=a^{m*n}\\\\\frac{a^{m}}{a^{n}}=a^{m-n}[/tex]
[tex]7^{7}*7^{5}=\frac{(7^{n})^{4}}{7^{4}}\\\\7^{7+5}=\frac{7^{n*4}}{7^{4}}\\\\7^{12}=\frac{7^{4n}}{7^{4}}\\\\7^{12}=7^{4n-4}[/tex]
Compare the exponents,
4n - 4 = 12 {Add 4 to both sides}
4n = 12 + 4
4n = 16
n = 16/4

18w2(squared) - w - 39
Answer:
w = 1.5 and -1.44
Step-by-step explanation:
Given the quadratic equation 18w^2 - w - 39
Using the general formuls
w = 1 ±√1²-4(18)(-39)/2(18)
w =1 ±√1+2808/36
w =1 ±√2809/36
w = 1+53/36 and 1-53/36
w = 54/36 and -52/36
w = 1.5 and -1.44

What is a trapezoid?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a trapezoid, one pair of opposite sides are parallel.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
In the isosceles trapezoid, the sum of the opposite angle is 180 degrees. Then the equation is given as,
∠NMQ + ∠NPQ = 180°
∠NPQ + 32° + 30° = 180°
∠NPQ = 118°
The measure of the angle ∠NPQ will be 118°. Then the correct option is C.

Find the size of angle AED?
Hey there .. here is ur answer

Please mark me as brainliest if you find it helpful ..

The size of angle AED is 173°
How to find the size of angle AED?In geometry, an angle is the figure formed by two rays (i.e. the sides of the angle) sharing a common endpoint (i.e. vertex).
Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes.
The size of angle AED can be determined as follow:
In ΔBCE,
∠BEC + 73° + 79° = 180° (The sum of angles on a triangle is 180°)
∠BEC = 180 - 73 - 79
∠BEC = 28°
Also, in ΔCDE,
∠BEC + 37° + 96° = 180° (The sum of angles on a triangle is 180°)
∠CED = 180 - 37 - 96
∠CED = 47°
∠BED = ∠BEC + ∠CED
∠BED = 28 + 47
∠BED = 75°
∠AED + ∠BED + ∠AEB = 360° (The sum of angles at a point is 360°)
∠AED + 75° + 112° = 360°
∠AED = 360 - 75 - 112
∠AED = 173°
Therefore, the size of angle AED is 173°.

What is the y-intercept of the line that passes through the points (2,-1) and (-3,9)
Answer:
The equation of the straight line y = -2x +3
y-intercept = 3 and m =-2
Step-by-step explanation:
Step(i):-
Given that the points are ( 2,-1) and (-3,9)
The slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{9-(-1)}{-3-(2)} = \frac{10}{-5} = -2[/tex]
Step(ii):-
The equation of the straight line passing through the point ( 2,-1) and slope m=-2
y-y₁ = m( x- x₁)
y -(-1) = -2 ( x-2)
y +1 = -2x +4
2x +y +1-4 =0
2x +y -3 =0
Final answer:-
The equation of the straight line y = -2x +3

A retailer sold an article to a customer at a loss of 10%. The customer purchased
it for Rs 25,425 including 13% VAT. Calculate the cost price of the article to the
retailer.
those who do this question i will mark us as a brilliant
Answer:
loss=10%
sp with vat=rs25425
sp=sp with vat-vat%of sp=rs25425-13/100×sp
sp+13/100×sp=rs25425
(100sp+13sp)/100=rs25425
113sp=rs2542500
sp=rs2542500/113=22500
cp=sp+loss %of cp
cp-10/100×cp=22500
(10cp-cp)/100=22500
9cp=2250000
cp=2250000/9=250000
A percentage is a way to describe a part of a whole. The cost price of the article is Rs. 25,000.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the selling price of the article be represented by x. Since the customet paid 13% vat , therefore,
x + 13% of x = Rs. 25,425
x + 0.13x = 25,425
1.13x = 25,425
x = 22,500
Thus, the selling price is 22,500.
Since the retailer had a 10% loss, therefore, the selling price will be 90% of the cost price.
90% of cost price = selling price
0.90×Cost price = 22,500
Cost price = 25,000
Hence, the cost price of the article is Rs. 25,000.
