Work out the size of angle x.

Answer:

x + 17 = 25

Step-by-step explanation:

x is "a number" and you just add it to 17. (Also the answer would be 8 if you need to solve it too)

The algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.

It is defined as the combination of constants and variables with mathematical operators.

We have:

A number plus 17 is 25 algebraic expressions:

Let x be the number:

x + 17 = 25

After solving:

x = 25 - 17

x = 8

Thus, the algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.

Answer:

The solution of the system is (5, 20).

Step-by-step explanation:

y = 4x and 3x + 2y = 55 are simultaneous equations. To find the unknowns, we have to solve these equations simultaneously.

The first can be rewritten as

4x – y = 0.

Therefore, we have:

4x – y = 0

3x + 2y = 55

Multiplying the first equation by 2 all through, we have

8x – 2y = 0.

So we can now combine the second equation with the first multiplied by 2.

8x – 2y = 0

3x + 2y = 55

Adding these equations we have:

11x = 55

Divide both sides by 11 and we have

x = 5

Substitute x = 5 in equation 1, we have

4(5) – y = 0

y = 20.

Therefore, x = 5 and y = 20.

The solution of the system is (5, 20).

Answer: D. (-7/2,3/2)

Step-by-step explanation: (apx)

The midpoint of the segment shown below is option D. (-7/2, 3/2).

Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.

Given a line segment with the given coordinates for the end points.

Midpoint of a segment with end points (x, y) and (x', y') is,

Midpoint = ((x + x') / 2, (y + y') / 2)

Here the end points of the segment are (-6, -2) and (-1, 5).

Midpoint of the segment = ((-6 - 1) / 2, (-2 + 5) / 2)

                                         = (-7/2, 3/2)

Hence the mid point of the segment is (-7/2, 3/2).

Answer:

The actual wall- 30

The width of the window blueprint- 1.5

Step-by-step explanation:

The actual wall- its the last answer you get for length

I just know the answer

The width of the window in the blueprint will be 2.7 inch.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

From the given table choose;

⇒ (x₁ , y₁ ) = (3, 5)  &  (x₂, y₂ ) = (3, 5)

Since, We know that equation of line is,

⇒ y – y₁  = ((y₂  – y₁)/(x₂ – x₁ )) (x – x₁)

⇒ (y - 3) = ((10-5)/(6-3))(x - 3)

⇒ 3(y - 3) = 5(x - 3)

⇒ 3y  = 5x -15+9

⇒  5x-  3y = 6  ….(i)

This is the required equation.

Given that; the length of wall on blue print = 10 inch

Then, put x = 10 in equation (i) we get;

⇒ 5x10 – 3y = 6

⇒ -3y = 6 - 50

⇒ y = 14.6 ft

The actual length be = 14.6 ft

And, Also given that actual width of window = 2.5 feet

Then put y = 2.5 in equation (i) we get

⇒ 5x – 7.5 = 6

⇒ 5x = 13.5

⇒ x = 2.7 inch

Thus, The width of the window in the blueprint is 2.7 inch.

Answer:

y=-2/5x-2

Step-by-step explanation:

First, you put x to the other side of the equation so you get y alone, getting the equation of -5y=-2x+10. In order to just have y on one side, you need to divide the whole equation by -5. This leads to the final answer of y=-2/5x-2.
