8 0

Because 80+40+30 equals 150 then you divide by how many number there are and there are 3 so 150 divided by 3 = 50

6 0

40x80=3200
3200/2=1600
So the answer is 1600

Write many equations that are equal to the equation 2x+4=x-4.

Jobisdone [24]

Answer:

x = -8

4x + 8 = 2x - 8

3x + 4 = 2x - 4

2x + 16 = x + 8

x - 1 = 2x + 7

17x + 36 = 16x + 28

13x + 2 = 12x + 11

.......

(this is infinite)

As long as it cancels out to x = -8

What is the length of BD?

I am Lyosha [343]

Answer:

$10\sqrt{3}$

Step-by-step explanation:

Trigonometric Ratios

This problem will be solved by the use of a trigonometric ratio called sine because it relates the opposite side of a given angle with the hypotenuse of the triangle.

Selecting the angle of 60° in triangle ABD:

Sine Ratio

$\displaystyle \sin 60^\circ=\frac{\text{opposite leg}}{\text{hypotenuse}}$

$\displaystyle \sin 60^\circ=\frac{BD}{20}$

Solving for BD:

$\displaystyle BD=20\sin 60^\circ$

Since

$\sin 60^\circ=\frac{\sqrt{3}}{2}$

$\displaystyle BD=20\frac{\sqrt{3}}{2}$

Simplifying:

$\boxed{\displaystyle BD=10\sqrt{3}}$

Graph the following inequality 6x-2y>8 Please help me and show me how to graph it.

Svetradugi [14.3K]

Answer:

6x - 2y > 8

First, solve the inequality (Isolate the y-variable & put it in function format):

$6x - 2y > 8\\-2y > 8 - 6x\\(-1)(-2y) > (-1)(8-6x)\\2y < 6x-8\\y < \frac{6x-8}{2} \\y < 3x - 4$

Second, graph the function y = 3x - 4 on the graph.

It should be linear.
Because the inequality is < and not ≤, the values on the line aren't included in the solution, so your line should be dotted, not solid.

Third, shade in the area below the line(where y-values are smaller).

Since the inequality is <, that means the solutions are smaller than the solutions of the function 3x - 4.
