Solve the equation below and explain how you solved it

x- 5 (x-1) = x- (2x-3)

(No bots or u will be reported)

Answers

Answer:

x = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

x - 5(x - 1) = x - (2x - 3) ← distribute parenthesis and simplify both sides

x - 5x + 5 = x - 2x + 3

- 4x + 5 = - x + 3 ( add x to both sides )

- 3x + 5 = 3 ( subtract 5 from both sides )

- 3x = - 2 ( divide both sides by - 3 )

x = [tex]\frac{2}{3}[/tex]

use cross multiplication to find 28N=84 and then divide both sides by 28 to get N=3

Step-by-step explanation:

Given Δ ABC is similar to Δ DEF , then the ratios of corresponding sides are in proportion, that is

[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values

[tex]\frac{21}{N}[/tex] = [tex]\frac{28}{4}[/tex] = 7 ( multiply both sides by N to clear the fraction )

A coordinate grid is shown below:

A coordinate grid from negative 2 to 0 to positive 2 is drawn. There are three grid lines between a whole unit on the grid.

Part A: Which point represents the origin? (2 points)

Part B: Starting from the origin, explain how to plot the following three points accurately:

(−1, 1)
(1, −1.5)
(2, fraction 1 over 4)
(8 points

Answers

Answer:

Part A: The origin would be (0, 0)

Part B:

(-1, 1)  starting from the origin (0,0), would move left 1 on the x-axis  then you would move up 1 on the y-axis

(1, -1.5)  starting from the origin (0,0), you would move to the right 1 on the x-axis, then you would move down 1.5 on the y-axis

(2, 1/4) starting from the origin (0,0), you would move to the right 2 on the x-axis, then you would move up 1/4 (.25).

a) The origin would be (0, 0).

What are Coordinates?

Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane. The x axis (horizontal) and y axis (Verticle) are the two axes that make up a coordinate plane.

Given:

a) The origin would be (0, 0).

b) First, (-1, 1) move left 1 on the x-axis then you would move up 1 on the y-axis

Second, (1, -1.5) move to the right 1 on the x-axis, then move down 1.5 on the y-axis

Third, (2, 1/4) move to the right 2 on the x-axis, then move up 1/4 (.25).

Answer:

a. 3x = 2x + 10, b. x = 10, c. 30 degrees

Step-by-step explanation:

Angle 4 and angle 6 = 180 degrees, so

3x = 2x + 10

x = 10

Angle 7 is congruent to angle 6, so it is also 2x + 10, x = 10, so it is 30 degrees.

Answer:

see explanation

Step-by-step explanation:

∠ 4 and ∠ 6 are same- side interior angles and sum to 180° , that is

(a)

3x + 2x + 20 = 180 , simplifying

(b)

5x + 20 = 180 ( subtract 20 from both sides )

5x = 160 ( divide both sides by 5 )

x = 32

(c)

∠ 6 and ∠ 7 are vertically opposite angles and are congruent , then

∠ 7 = 2x + 20 = 2(32) + 20 = 64 + 20 = 84°

Jacob scored 25 in his test last week and then this week scored 70.

The increase can be found as:

= (New score - Old score) / Old score x 100%

Solving gives:

The diagonal is the hypotenuse of the right triangle whose sides are the sides of the rectangle. The Pythagorean theorem applies.

  height² + base² = diagonal²

  height² +24² = 26²

  height² = 676 -576 = 100

  height = √100 = 10

The area is the product of the base and height.

  A = bh

  A = (24)(10) = 240

The equation of the line for the graph that has y-intercept (0, 6) and contains the point (2, 1) is; y = -2.5x + 6

What is the Equation of the Line in Slope Intercept form?

The general form of the equation of a Line in Slope Intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

We are told that the graph has the points (0, 6) and (2, 1). Thus, the formula for slope is;

m = (y₂ - y₁)/(x₂ - x₁)

m = (1 - 6)/(2 - 0)

m = -5/2

m = -2.5

Now, since the y-intercept is at (0, 6), then it means that;

c = 6

Thus, the equation of the line is; y = -2.5x + 6

Find the measure of the angle x to the nearest tenth. Question 7 options: 33. 5° 56. 5° 28. 9° 44. 3°.

Answers

The question is an illustration of right-angled triangles

The approximated value of x is 33.5 degrees

The given parameters are:

[tex]\theta = x[/tex]

[tex]Hypotenuse = 58[/tex]

[tex]Opposite = 32[/tex]

To determine the measure of angle x, we simply make use of the following sine ratio.

[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]

So, we have:

[tex]\sin(x) = \frac{32}{58}[/tex]

[tex]\sin(x) = 0.5517[/tex]

Take arc sine of both sides

[tex]x = \sin^{-1}(0.5517)[/tex]

This gives

[tex]x = 33.5[/tex]

Hence, the approximated value of x is 33.5 degrees
