#6) BRAINLIEST + 10 + POINTS! :D

Mathematics
1 answer:
kumpel [21]3 years ago
4 0

Answer:

B

Step-by-step explanation:

Notice that if we divide our given equation (2x - 4 = 6) by 2 from both sides, we get:

(2/2)x - (4/2) = (6/2)

x - 2 = 3

Now, notice what happens if we multiply this by -3:

-3 * (x - 2) = 3 * (-3)

-3 * x + (-3) * (-2) = -9

-3x + 6 = -9

This matches B.

Hope this helps!

Find value of x <br> How do I find the solution to this?
SashulF [63]
Adding all of these should equal to 180 from the way the angle is set up.

So the equation should be:

(3x + 2) + (2x + 5) + (2x - 9) = 180

You can remove parentheses as it doesn’t affect the equation since it is all addition.

Let’s first add the common variables together.

3x + 2x + 2x = 7x
2 + 5 + (-9) = -2

So now we should have:

7x - 2 = 180

Now add 2 to both sides.

7x = 182

Divide both sides by 7 to isolate x.

x = 26

So x is 26.

Need help ASAP !!!!<br> Solve for angle A
avanturin [10]
Since vertical angles are equal you can put the same value to the opposite angles. Also, you were given a supplementary angle which are two angles added to 180 degrees. Of those 180 you were given 100. The angle next to the 100 degrees has a value of 80. With all this, you add all the angles together and put it equal to 180 which is what the angles of a triangle add up to. Then you combine like terms to get the value of X and just replace it for x. After that you just multiply and then add.

Darren is on a super efficient diet. He started with 210 pounds 2 months ago and he now weighs 150 pounds . Find his percent of
ikadub [295]

Answer:

29%

Step-by-step explanation:

210-150/210 = 60/210 or 6/21

Now we have to find the percent out of 100 so we have to find out 100/21 to see what we have to multiply by to get to 100 so we can do the same with the 2 (numerator) so 1000/21= 4 16/21

then we have to multiply the 6 by 4 16/21 which is about 29%

Simplify -4+5x-17-22x
Elina [12.6K]
<h3>Answer:</h3>

\large\boxed{-17x-21}

<h3>Step-by-step explanation:</h3>

In this question, we're simply combining "like-terms" in order to simplify the expression.

Lets solve:

-4+5x-17-22x\\\\\text{First, lets add 5x and -22x}\\\\-17x-4-17\\\\\text{Now we would add the -4 and -17. Adding 2 negatives still keeps it a negative}\\\\-17x-21

When you're done solving, you should get -17x-21

This means that -17x-21 would be the simplified version.

<h3>I hope this helped you out.</h3><h3>Good luck on your academics.</h3><h3>Have a fantastic day!</h3>
