4 - 2a = 16

  -2a  = 16 - 4

   -2a = 12

      a = 12/-2

a = -6

a - 2b = b

-6 - 2b = b

    -6    = b + 2b

      -6  = 3b

    -6/3  = b

b = -2

b - 2c = a

-2 - 2c = -6

    -2c = -6 +2

    -2c = -4

        c = -4/-2

c = 2

a - 2d = c

-6 - 2d = 2

     -2d = 2 + 6

     -2d = 8

        d = 8/-2

d = -4

Answer:

b

Step-by-step explanation:

The number that makes the given expressions equivalent is -0.7.

An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.

The variable part of an algebraic expression can never be added or subtracted from the constant part.

The given expression is as below,

1/2 (-1.4m + 0.4) = ?m +0.2

Suppose the unknown number be x.

Then the given expression can be written as,

1/2 (-1.4m + 0.4) = xm + 0.2

=> -0.7m + 0.2 = xm + 0.2

=> -0.7m = xm

=> x = -0.7

Hence, the missing number in the given expression is -0.7.

According to the given statement  the value of sin x = 8/10

A mathematical field called trigonometry examines connections between triangles' sides and angles. Due to the fact that every straight-sided shape can be decomposed into a group of triangles, trigonometry can be found throughout all of  geometry.

To roof a home, to make the roof slant (in the case of single-family bungalows), to determine the height of a roof in buildings, etc., use trigonometry. The naval and aviation industries use it. It's applied to cartography (creation of maps). Trigonometry is also used in satellite navigation systems.

sin x = 4/5

We know that:

Sin x = opposite/Hypotenuse.

So,

When the triangle is enlarged, the opposite side will increase to an angle of 8, and the hypotenuse will increase to an angle of 10.

= 4/5 we multiply by 2 with 4 and 5 we get:

= 8/10

4/5 will result from simplifying 8/10. Thus, nothing has changed.

So the value of sin x = 8/10.

Answer:

  see attached

Step-by-step explanation:

To plot the line through the point, plot the point. Then find another point that has the given "rise" and "run". Draw the line through the two points.

__

The given point is (-7, -4). Locate that on the graph.

The slope is given as -2/3. This is the ratio of "rise" to "run", so it means the "rise" will be -2 for each "run" of 3. (rise/run = -2/3)

The rise is the vertical change. So, you want your second point to be 2 units below the given point. Its y-coordinate will be -4-2 = -6.

The run is the horizontal change. Your second point will be 3 units to the right of the given point, so its x-coordinate will be -7+3 = -4. Now, you can plot the point (-4, -6) and draw your graph through these two points.

Step-by-step explanation:

took the test

Answer:

(x – 2)(x + 5)(x – 3)

The value is approximate.

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

Explanation:

Focus on the upper triangle.

Label the unknown horizontal side as y

Use the pythagorean theorem to solve for y

a^2+b^2 = c^2

10^2 + y^2 = 26^2

100+y^2 = 676

y^2 = 676-100

y^2 = 576

y = sqrt(576)

y = 24

-----------

Now move to the bottom triangle

With respect to the reference angle, the side y = 24 is opposite this. The hypotenuse is unknown.

Use the sine rule to connect the two and solve for x

sin(angle) = opposite/hypotenuse

sin(32) = y/x

sin(32) = 24/x

x*sin(32) = 24

x = 24/sin(32)

x = 45.2899179551967 which is approximate

x = 45 rounding to the nearest whole number

Side x is approximately 45 cm long.

Note: make sure your calculator is in degree mode.

Answer:

Rise/run

Step-by-step explanation: You count how many it rises by and how many it runs. Hope this helps!

the length of the side x will be 3.61 mm and the length of the side y will be 7.48 mm.

We are given the two right angle triangles.

For the smaller triangle:

Side 1 = 3 mm

Side 2 = 2 mm

Side 3 = x mm

Now, by using the Pythagoras theorem, we get that:

3² + 2² = x²

x² = 9 + 4

x² = 13

x = √13 mm

x = 3.61 mm

For the larger triangle:

Side 1 = 5 mm

Side 2 = y mm

Side 3 = 9 mm

Now, by using the Pythagoras theorem , we get that:

5² + y² = 9²

y² = 81 - 25

y² = 56

y = √56 mm

y = 7.48 mm

Therefore, we get that, the length of the side x will be 3.61 mm and the length of the side y will be 7.48 mm.

Answer:

m∠3 = 49°

Step-by-step explanation:

From the picture attached,

lines m and n are the parallel lines and line t is a transversal line intersecting these parallel lines at E and B respectively.

Therefore, ∠DEF ≅ ∠ABC [Exterior alternate angles]

m∠1 + m∠2 = m∠4 + m∠5

m∠4 = m∠5 [line s bisects ∠ABC]

50° + 48° = m∠4 + m∠4

98° = 2m∠4

m∠4 = 49°

Since, ∠4 ≅ ∠3 [Vertically opposite angles]

m∠3 = 49°

Answer:

85

Step-by-step explanation:

To solve, use the Pythagorean Theorem, which says c² = a² + b². Enter 84 as a and 13 as b and square them both. This will give you 7056 for a, and 169 as b. Add them to get 7225. So, c² = 7225. Find the square root of this to get 85. So, the third side is 85 in length.
