Answer:

9 and 11

Step-by-step explanation:

20 = 9 + 11

Algebraic approach

let the 2 consecutive odd numbers be n and n + 2 , then

n + n + 2 = 20 , that is

2n + 2 = 20 ( subtract 2 from both sides )

2n = 18 ( divide both sides by 2 )

n = 9 and n + 2 = 9 + 2 = 11

The 2 numbers are 9 and 11

Step-by-step explanation:

Answer:

x = 19.6

Step-by-step explanation:

If we need to find the value of x then first we need to

(7x-25) + (3x +9) = 180  (angles at the same side of transversal will be equal to 180 degree )

10x -16 = 180

10x = 180 +16

10x = 196

x = 196/10

x = 19.6

a or b bc tt could be any number but in saying that it could be 1 or it could be 2000

Step-by-step explanation:

Answer:

False.

Step-by-step explanation:

Using the property of distribution, (a + b)² will be a² + b², never a² + b.

No, for any two integers a and b, (a + b)² ≠ a² + b is a false statement.

For the given two integers a and b,

The given expression

(a + b)² = a² + b (false statement)

The correct statement is-

(a + b)² = (a + b)(a + b)

(a + b)² = a² + b² +  2ab

Thus, no, for any two integers a and b, (a + b)² ≠ a² + b.

Answer = 7t - 4

Answer:

Yes, the value of x does answer the question since the question is asking how much do the two have on their subway cards. This is an example question so the answer is given to you for you to read. I'm not sure if this is what you're confused about, but the answer does answer the question.

Answer:

Yes

Step-by-step explanation:

If 2x + 20 is 1.5x more than x + 20 then we get:

2x + 20 = 1.5(x + 20)

since 2x + 20 is 1.5x more than x + 20.

If we solve then we get the same answers as the example where x = 20 and 2x = 40.

Answer:

m∠1= 80

m∠2= 100

m∠3= 80

Step-by-step explanation:

Given: m∠1= 2x +40

m∠2= 2y +40

m∠3= x +2y

m∠1 +m∠2= 180 (adj. ∠s on a str. line)

2x +40 +2y +40= 180

2x +2y+ 80= 180

2x +2y= 180 -80

2x +2y= 100

2(x +y)= 100

x +y= 100 ÷2

x +y= 50 -----(1)

m∠1= m∠3 (vert. opp. ∠s)

2x +40= x +2y

2x -x +40= 2y

x= 2y -40 -----(2)

Substitute equation (2) into (1):

2y -40 +y= 50

3y= 50 +40

3y= 90

y= 90 ÷3

y= 30

Substitute y= 30 into equation (2):

x= 2(30) -40

x= 60 -40

x= 20

m∠1

= 2x +40

= 2(20) +40

= 40 +40

= 80

m∠2

= 2y +40

= 2(30) +40

= 60 +40

= 100

m∠3

= x +2y

= 20 +2(30)

= 20 +60

= 80

Alternatively, since m∠1= m∠3,

m∠3

= m∠1 (vert. opp. ∠s)

= 80

Answer:

(4,-3)

Step-by-step explanation:

A rotation is when we move a point based on a point of a fixed point called the center. For example, a clock. A clock rotated it's hand around the middle part of the clock.

A 180 degree rotation negate a point if rotated about the origin. 180 degree rotation counter or clockwise doesn't matter when we rotate about the origin. In other words. they are the same.ONLY WHEN WE ROTATE 180 OR 360 degrees.

The rotation formula when rotating 180 degrees is

[tex](xy)[/tex]

goes

[tex]( - x )(- y)[/tex]

In other words, we negate both points to find our new coordinates.

-(-4)=4 and

-3=-3

So our new point is

(4,-3)

Answer:

Step-by-step explanation:

Matrices can be multiplied together if the number of columns in the first matrix equals the number of rows in the second matrix.

A is of order (3 × 2) and B of order (2 × 3 )

Since the 2 in the first and the 2 in the second match , the matrices can be multiplied

The resulting matrix is of order (3 × 3 )

This is obtained from the first 3 in order of A and the second 3 in order of B

Then AB is defined and the resultant matrix is of order 3 × 3

Answer:

X = 6 , – 2

Step-by-step explanation:

| 4x +4| - 10 =3x

4x +4 - 10 = 3x

4x - 3x = 10 - 4

x = 6

_____o___o____

– (4x + 4) – 10 = 3x

– 4x – 4 – 10 = 3x

3x + 4x = – 4 – 10

7x = – 14

x = – 14/ 7

x = – 2

I hope I helped you^_^

Step-by-step explanation:

|4x + 4| - 10 = 3x

4x + 4 - 10 = 3x

4x - 6 = 3x

4x - 3x = 6

x = 6

The inequalities represents the number of students the classroom can

accommodate is Number line C.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

We have,

A classroom can accommodate less than 24 students.

For less than we use the inequality as '<'.

let the x be the number of students than the condition is

x < 24.

Now, For '<' inequality the arrow should head towards left side of 24 which means for x= 23, 22, 21, .....

Thus, the number line for the situation is C.
