Answer:
The answer is A because there are no coefficients which is a letter and 1 term.
express the following linear equation in the form of ax+by+c=0 and indicate the value of a,b and c. 2x+3y=-5
Answer:
2x+3y+5=0
a = 2 b = 3 c=5
Step-by-step explanation:
We are asked to express 2x+3y=-5 in the form ax+by+c=0
Add 5 to both sides
2x+3y+5=0
We can now find the values of a, b and c now that the equation is in standard form.

3 more than 2 times a number is equal to that number plus 4. What is the number?
Answer:
number is 1
Step-by-step explanation:
let the number be n , then 2 times the number is 2n and 3 more than this is
2n + 3 , so
2n + 3 = n + 4 ( subtract n from both sides )
n + 3 = 4 ( subtract 3 from both sides )
n = 1
That is the number is 1
The required number is 1 which represents "3 more than 2 times a number is equal to that number plus 4"
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
Let the required number would be x.
According to the given question, translate the phrase into an algebraic equation:
3 + 2x = x + 4
Subtracting x from both sides gives:
3 + 2x - x = x + 4 - x
Simplifying the left side gives:
3 + x = 4
Subtracting 3 from both sides gives:
3 + x - 3 = 4 - 3
Simplifying the left side gives:
x = 1
Therefore, the required number would be 1.

Other two sides are (x-2) and 8.
To find:
The value of x.
Solution:
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Putting the given values, we get
[tex]x^2=(x-2)^2+(8)^2[/tex]
[tex]x^2=x^2-4x+4+64[/tex]
[tex]x^2-x^2+4x=68[/tex]

Divide both sides by 4.
[tex]x=\dfrac{68}{4}[/tex]

Find the values of x and y . Then find the measures of the interior angles of the polygon.
Step-by-step explanation:
It is a cyclic quadrilateral.
The sum of interior angles of this polygon is equal to 180 degrees.
ATQ,
2x+26y=180
x+13y=90 ....(1)
3x+21y=180
x+7y=60 ....(2)
Subtract equation (1) from (2).
x+7y-(x+13y) = 60-90
x+7y-x-13y=-30
-6y=-30
y = 5
Put the value of y in equation (1
x+13(5) = 90
x+65=90
x = 90-65
x = 25
So,
∠DAB = 26y = 26(5) = 130°
∠ABC = 3x = 3(25) = 75°
∠BCD = 2x = 2(25) = 50°
∠ADC = 21y = 21(5) = 105°
x = 25, y = 5
m∠DAB = 26(y) = 180°
m∠ABC = 3x = 75°
m∠BCD = 2x = 50°
m∠ADC = 21y = 105°
Property of a cyclic quadrilateral: Sum of the opposite angles of a cyclic quadrilateral is 180°.
From the picture attached,
ABCD is a cyclic quadrilateral. m∠A = 26y°, m∠B = 3x°, m∠C = 2x° and m∠D = 21y°By using the property of cyclic quadrilateral,
m∠A + m∠C = 180°
26y + 2x = 180
13y + x = 90 --------(1)
m∠B + m∠D = 180°
3x + 21y = 180
x + 7y = 60 --------(2)
Subtract equation (2) from (1),
(13y + x) - (x + 7y) = 90 - 60
6y = 30
y = 5
Substitute y = 5 in equation (1),
13(5) + x = 90
x = 90 - 65
x = 25
Substitute the values of 'x' and 'y' to get the measures of the angles,
m∠DAB = 26(y) = 180°
m∠ABC = 3x = 75°
m∠BCD = 2x = 50°
m∠ADC = 21y = 105°
Therefore, values of the variables will be,
x = 25, y = 5
m∠DAB = 26(y) = 180°
m∠ABC = 3x = 75°
m∠BCD = 2x = 50°
m∠ADC = 21y = 105°

Answer:
21
Step-by-step explanation:
Well you basically divide 3 and 1/2 by 1/6 which you would you have to simplify the 3 and 1/2 which is 7/2 and switch the denominator and numerator of the 1/6 which would be 6/1 and after you multiply(7/2 x 6/1=42/2) it would be 42/2 which you would have to simplify by dividing 42 and 2 which is 21. There you go I hope this helps.
Answer:
21.
Step-by-step explanation:
That would be 3 1/2 divided by 1/6.
= 7/2 / 1/6
= 7/2 * 6
= 42/2

Answer:
See below.
Step-by-step explanation:
The 3 marked angles add up to 360 degrees.
5x + 12 + 10x - 37 + 9x + 1 = 360
24x - 24 = 360
24x = 384
x = 384/24 = 16
The large angle at C = 10(16) - 37
= 160 - 37 = 123 degrees.
So m <BCA = 180 - 123
= 57 degrees (adjacent angles add up to 180).
