8+2x≤6x-20

Answer: x=7

Step-by-step explanation:

Simplifying

8 + 2x = 6x + -20

Reorder the terms:

8 + 2x = -20 + 6x

Solving

8 + 2x = -20 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

8 + 2x + -6x = -20 + 6x + -6x

Combine like terms: 2x + -6x = -4x

8 + -4x = -20 + 6x + -6x

Combine like terms: 6x + -6x = 0

8 + -4x = -20 + 0

8 + -4x = -20

Add '-8' to each side of the equation.

8 + -8 + -4x = -20 + -8

Combine like terms: 8 + -8 = 0

0 + -4x = -20 + -8

-4x = -20 + -8

Combine like terms: -20 + -8 = -28

-4x = -28

Divide each side by '-4'.

x = 7

Simplifying

x = 7

Complete the conditional statement. If -2a > 6, then _____. a > 3 a < 3 a < -3 a > -3
Ivanshal [37]
Hi there!

Let's solve this inequality step by step!
- 2a > 6

First divide both sides by 2.
- a > 3

To find the value of a, we must get rid of the negative sign in front of it, so we divide both sides by -1. When dividing by a negative, we must flip the sign.

Hence,
a < - 3

Additonal note:
This solution makes sense because of the following reason: when a number that has been made negative is bigger than 3, the number itself must be smaller than -3 (when we add an extra minus sign to -3, it becomes 3; so every number smaller than -3 will become bigger than 3 when we add another minus sign).

~ Hope this helps you!

Find the value if k(2,3)is a point on graph of the equation x - ky +8= 0​
Anettt [7]

Answer:

k = 3.33

Step-by-step explanation:

x = 2

y = 3

x - ky + 8 = 0

2 - k(3) + 8 = 0

2 - 3k + 8 = 0

10 - 3k = 0

<u>-10         -10</u>

-3k = -10

k = 3.33

Help please I’ll give brainliest
Luden [163]

I don't see any question there ... just a bunch of pretty rulers.

I'm going out on a limb here, and I'm gonna assume that the question is "Identify the number to which the arrow on each ruler is pointing.".

If that's the question, you're welcome.  If not, ignore everything I'm about to say.

Orphan ruler on page-1: 6 and 1/4

Rulers on page-2, starting at the top and working down:

6 and 3/8

1

3 and 5/8

2 and 1/2

7 and 3/4

4 and 7/8

5 and 1/8

9 and 1/2 .

If these answers are not helpful, remember:  I'm the one who had to invent the question, and for the question that I invented, these answers are all correct !
