Answer:

3x = -2 2/5 or -2.4

Step-by-step explanation:

5x + 8 = 4

5x = 4 - 8

5x = -4

x = -4/5

3x = y  If x = -4/5

3 * -4/5 = y

-12/5 = y

-2 2/5 = y

5x + 8 = 4
5x = -4
x = -4/5
3(-4/5) = -2.4
Solution: 3x = -2.4

Match the reasons with the statements in the proof.
Len [333]

Observe the given figure.

Given: m \angle 1 = m \angle 3, m \angle 2 = m \angle 3

To prove: l \parallel m

Statement                                                      

1.  m \angle 1 = m \angle 3, m \angle 2 = m \angle 3

Reason: Given

2. m \angle 1 = m \angle 2

Reason: Substitution

3. \angle 1,\angle 2 are alternate interior angles.

Reason: Definition of alternate interior angles

4. l \parallel m

Reason: If alternate interior angles are equal, then the lines are parallel.

Step One
Find the base area  of the large hexagon as though the smaller one was not removed.

Area = 3*Sqrt(3) * a^2 /2 where a is the length of one side of the hexagon
a = 5
Area = 3*sqrt(3) * 25/2 = 75 sqrt(3) / 2 of the large hexagon without the smaller one removed.

Step Two
Find the area of the smaller hexagon. In this case a = 4
Area2 = 3*sqrt(3)*16/2 = 3*sqrt(3)*8 = 24 sqrt(3)

Step Three
Find the area of the thick hexagonal area left by the removal of the small hexagon.

Area of the remaining piece = area of large hexagon - area of the small hexagon

Area of the remaining piece = 75 *sqrt(3)/2 - 24*sqrt(3)

Step Four
Find the volume of the results of the area from step 3
Volume = Area * h
h = 18
Volume = (75 * sqrt(3)/2 - 24*sqrt(3))* 18

I'm going to leave you with the job of changing all of this to a decimal answer. I get about 420 cm^3

I need help with this question<br><br><br><br> -2(x + 1) = -2x + 5
soldi70 [24.7K]

Answer:

No solution

Step-by-step explanation:

Apply the distributive property:

-2x - 2 = -2x + 5

Add 2x to each side:

-2 = 5

Since negative two never equals five, there is no solution to this equation.
