solve the equation (-10x + 1 + 7x = 37)

Answers

Answer:

x = - 12

Step-by-step explanation:

- 10x + 1 + 7x = 37

- 3x + 1 = 37

- 3x + 1 - 1 = 37 - 1

- 3x = 36

- 3x ÷ - 3 = 36 ÷ - 3

x = - 12

Answer: x = -12

Step-by-step explanation: first you combine like terms/simplify the equation: -10x + 1 + 7x = 37 turns into -3x + 1 = 37.

then subtract 1 from both sides: -3x + 1 = 37 then -3x + 1 - 1 = 37 - 1 then -3x = 37 - 1 then -3x = 36.

then divide both sides of the equation by -3 and then you're done

Which expression is equivalent to 24x2 - 22x + 5?​

Answers

Answer:

C

Step-by-step explanation:

Given

24x² - 22x + 5

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 24 × 5 = 120 and sum = - 22

The factors are - 12 and - 10

Use these factors to split the x- term

24x² - 12x - 10x + 5 ( factor the first/second and third/fourth terms )

= 12x(2x - 1) + 5(2x - 1)  ← factor out (2x - 1) from each term

= (12x - 5)(2x - 1) ← in factored form → C

8p²-18p² need help from brainliest​

Answers

Answer:

- 10p2

Step-by-step explanation:

p(8p - 18 p)

p x -10p

ans = -10p2

Answer:  -10p²

This is the same as saying -10p^2

============================================

Explanation:

Both terms 8p² and -18p² are like terms.

We combine them in much the same way as 8-18 = -10, just with a p² attached to everything.

So 8p² - 18p²  = (8-18)p² = -10p²

The coefficient -10 is negative because we're subtracting small minus big. If it was the other way around, then we'd get a positive value.

What is the value of x?

7

Answers

Answer:

x = 2

Step-by-step explanation:

AE is equal to the sum of AB and BE because of segment addition postulate, we can substitute to get AE = 11 + x + 1 = x + 12

DE is equal to the sum of DC and CE because of segment addition postulate, we can substitute to get DE = 1 + x + 4 = x + 5

To solve the problem, we can use power of a point, more specifically exterior secants products scenario. In this case, we can get the equation:

AE * BE = DE * CE

Now, we can substitute and solve:

(x + 12)(x + 1) = (x + 5)(x + 4)

x^2 + 13x + 12 = x^2 + 9x + 20

13x + 12 = 9x + 20

4x + 12 = 20

4x = 8

x = 2

The diagonals of a rectangle are AC = 5x-4 and BD = 7x-18.
Solve for x

Answers

Answer:

x = 7

Step-by-step explanation:

The diagonals of a rectangle are congruent , so

BD = AC , that is

7x - 18 = 5x - 4 ( subtract 5x from both sides )

2x - 18 = - 4 ( add 18 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Congruent angle pairs : Find value of x

Answers

Answer:

(Opt.B) 18

Step-by-step explanation:

4x = 2y - x (vertically opposite angles are equal)

4x + x = 2y

5x = 2y ----- (1)

4x + 2y + x = 180 (Linear pair angles)

5x + 2y = 180

From (1) we can understand that, the value of 5x and 2y is the same. So,

5x + 5x = 180

10x = 180

x = 180/10

x = 18

Just completing,

Putting the value of x in (1)

5*18 = 2y

90 = 2y

90/2 = y

45 = y

At which angle will the hexagon rotate so that it maps
onto itself?
O 60°
90°
0 120°
O 180°

Answers

Answer:

60 degress

Step-by-step explanation:

Edgen 2021

60° is the angle at which the hexagon rotate so that it maps onto itself.

What is Polygon?

A polygon is a plane figure made up of line segments connected to form a closed polygonal chain.

When a figure has a rotational symmetry, it maps onto itself under rotation about a point at the centre.

When an hexagon rotate onto itself,the vertices must cover to vertices and from sides to sides.

There are six angles in a hexagon and the sum of the angles is 360°. Therefore, each angle has a measure of 360°/6 is equal to 60°.

Rotating subsequently by 60 degree will rotate a hexagon onto itself. A hexagon has 6 rotations, that is, a hexagon has a rotational symmetry of 6 and at angle 60°, the hexagon will rotate onto itself.

Hence,  60° is the angle at which the hexagon rotate so that it maps

onto itself.

At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed?

a. |19|

b. |-19|

c. |-30|

d. |-38|

Answers

Answer:

c. |-30|

Step-by-step explanation:

It wants the change from 11 to -19. While normally absolute value is the distance from zero, zero can be shifted. Depending on where you are in learning about absolute value, the midway point can change from zero to, say, 4. This is called a transformation and is typically represented on a graph. Simple answer is that zero is shifted to 11. Therefore, absolute value changes from distance away from zero, to distance away from 11.
