The sum of numbers is 28. the difference of two numbers is -2. find the numbers​

Answers

I believe 15 and 13. 13-15=-2 and added is 28....?

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

a man makes a profit 15% by selling an article for rs.250. for what amount should he sell it to make profit of 38%​

Answers

Answer:

$300

Step-by-step explanation:

original price = $250

the profit= 15%

ok now let the cost price of article be ₹ x

x + 15% of x = 250

1.15x = 250 => 115x ÷ 100 = 250

115x = 25000 => x = 25000 ÷ 115

x = 5000/ 23

cost price of article = ₹5000/ 23

required profit = 38%

= 38% of 5000/ 23 = 0.38 × 5000/ 23

= 1900/ 23

the required will be selling price to gain about 38%

= cost price + required profit which is

= (5000/ 23) + (1900/ 23)))

= 6900/ 23 = $300

Answer:  now its required selling price = $300

The area of Jordan’s yard can be modeled by the expression 3x2 – 2x + 1. Jordan purchases additional land from his neighbors. The area of this land can be modeled by the expression 4x2 + 3x + 7. Which expression represents the new area of Jordan’s yard?

A.
x2 + 5x + 6

B.
x2 + x + 8

C.
7x2 + x + 8

D.
7x2 + 5x + 6

Answers

Answer:

7x^2 + x + 8

Step-by-step explanation:

here's your solution

=> The model of Jordan yard = 3x^2 - 2x + 1

=> The model of new yard = 4x^2 + 3x+ 7

=> now, for total area we need to add both

=> 4x^2 + 3x^2 + 3x - 2x + 7 + 1

=>7x^2 + x + 8

If C = 2x^2+5x-1 and D = x-1 find an expression that equals C-3D in standard form.

Answers

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 )

Choices- 333.50, 63.50, 153.50, 166.75

Answers

Answer: 153.50

180-13.25-13.25 = 153.50

The two acute angles are the same so look for the obtuse.

Answer:

153.50

Step-by-step explanation:

Sum of all interior angles of a triangle is 180°.

Option(1): 333.5 is much greater than 180(sum of all angles). 333.5 + 13.25 + angle P = 180, for all +ve values of angle P.

/_P = 180° - 13.25 - 333.5 , /_P is -ve from this which is impossible(for an angle in triangle)

This is incorrect.

Option(2): As it can observed, /_ R is much greater than 90°. It means, it should be greater than 63.50°.

This is incorrect.

Option(3): 153.50 is greater than 90°. Moreover, if /_ R is 153.5, let /_P be x, then,

=> 13.25 + 153.50 + x = 180°

=> x = 13.25. , which is +ve

So we can say /_P = 153.50

Option(4): if /_ R is 153.5, let /_P be x, then,

=> 13.25 + 166.75 + x = 180°

=> x = 0 , which is impossible(as we can see It's not 0)

Incorrect.

Which equation is modeled on the number line?
A -7 -− 10 = -17 B 7 -− 10 = -3 C 7 -− (-10) = 17 D -7 -− (-10) = 3

Answers

Answer:

Option D

Step-by-step explanation:

For addition we move right on the number line and for subtraction we move left.

So, (-7) represents a 7 units to the left from the zero.

Then move 10 units right from (-7),

Therefore, (-7) + 10 = 3

Or (-7) - (-10) = 3

Option D is the correct option.
