The sum of numbers is 28. the difference of two numbers is -2. find the numbers
Answer:
x=13 and y=15
Step-by-step explanation:
Let the 2 numbers be x and y
ATQ,
x+y = 28 ------ eqn.1
x-y=-2 -------- eqn.2
Adding both the equations:
x+y=28
+x-y=-2
_______
2x = 26
Therefore x=13
Now substituting the value of x in eqn. 1
x+y=28
13+y=28
Therefore y=28-13
=15

Step-by-step explanation:
The mathematical expression is -18 9/17 + (-18 9/17). And the value of this expression will be -36.53.
What is a fraction?Fraction is the numeral that is got by the division of the numerator by the denominator. Fraction s a rational number.
Given here the expression is minus 18, start fraction, 9, divided 17, end fraction, plus, left parenthesis, minus, 18, start fraction, 9, divided, 17, end fraction, right parenthesis
We have to first convert this long expression into a mathematical expression
The first expression is minus 18, start fraction, 9, divided 17, end fraction
by converting this into mathematical expression it will be
-18 9/17
The second expression is left parenthesis, minus, 18, start fraction, 9, divided, 17, end fraction, right parenthesis
by converting this into mathematical expression it will be
(-18 9/17)
Then the whole mathematical expression will be
-18 9/17 + (-18 9/17)= -36 9/17= -36.53
Therefore the mathematical expression is -18 9/17 + (-18 9/17). And the value of this expression will be -36.53.

Answer:20
Step-by-step explanation:
In the figure, lines a and b are parallel lines. Select all the statements that are true.
Answer:
m<2 = m<6
m<1 + m<6 = 180
x - 15= 180 - 75 → x = 120°
Find the value of x that will make a||b
The location of each angle make them vertical angles. For the lines to be parallel the two angles need to be equal to each other.
5x + 20 = 3x + 60
Subtract 3x from both sides:
2x + 20 = 60
Subtract 20 from both sides:
2x = 40
Divide both sides by 2:
X = 20

Answer:
Positive association
Step-by-step explanation:
You can see the weight go up by the model number going up, if you put it on a graph it will show the trend line going up.
So say
"This has a positive association because the weight is going up while the model # is going up. thus gives a positive association when graphed"

What is the area of the logo?
Answer:
[tex]the \: area \: of \: the \: logo \: is \: {91cm}^{2} [/tex]
Step-by-step explanation:
To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.
Area of the square.
To calculate the area of the square you have to calculate the square of one of its sides, following the formula:
[tex]a = {a}^{2} [/tex]
Where "a" is the length of one of its side.
The side length of the square is a=7cm, so its area will be:
[tex]asquare = {7}^{2} \\ asquare = {49cm}^{2} [/tex]
Area of the triangles.
The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.
To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:
[tex]a = \frac{b.h}{2} \\ a = \frac{7.4}{2} \\ a = \frac{28}{2} \\ a = {14cm}^{2} [/tex]
The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:
[tex]atriangles = 3a \\ atriangles = {42cm}^{2} [/tex]
Now that the area of all shape are calculated, you have to add them to determine the area of the logo:
[tex]alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo = {91cm}^{2} [/tex]

If C = 2x^2+5x-1 and D = x-1 find an expression that equals C-3D in standard form.
Answer:
2x^2+2x+2 or 2(x^2+x+1)
Step-by-step explanation:
C = 2x^2+5x-1
D = x-1
C-3D = (2x^2+5x-1) - 3 * (x-1) =2x^2+5x-1-3x+3 =2x^2+2x+2 = 2(x^2+x+1)
The value of the equation C - 3D = 2 ( x² + x + 1 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the value of the expression be A
Now , the value of equation C is
C = 2x² + 5x - 1
And , the value of equation D is
D = x - 1
So , the value of the equation C - 3D is given by
3D = 3 ( x - 1 )
3D = 3x - 3
So , the equation is
The value of C - 3D = 2x² + 5x - 1 - ( 3x - 3 )
On simplifying the equation , we get
The value of C - 3D = 2x² + 5x - 1 - 3x + 3
On adding the similar terms in the equation , we get
The value of C - 3D = 2x² + 2x + 2
Taking 2 as the common factor of the equation , we get
The value of C - 3D = 2 ( x² + x + 1 )
Therefore , the value of the expression A is 2 ( x² + x + 1 )
Hence , The value of the equation C - 3D = 2 ( x² + x + 1 )
