Solve the equation below. you must show all your work, and have the correct answer.

9x + 10 = 12x – 11

Answers

Answer 1

Answer:

x=7

Step-by-step explanation:

You need to bring 9x to the right side and bring '-ll' to the left side so it will be 11+10 = 12x-9x. Then you calculate 11+10, which is 21, then you subtract 12x to 9x. Then it will be 21 = 3x. Lastly, you divide 3 on both sides of the equation and get x to be 7!

Answer 2

Answer:

x=7

Step-by-step explanation:

9x+10=12x-11

-9x. -9x. subtract 9x from both sides

10 = 3x-11

+11 +11. add 11 to both sides

21 =3x

divide by 3x (21 ÷3=7) therefore x=7

Answer:

x=55

Step-by-step explanation:

125+125=250

250+2x=360

2x=110

x=55

Answer:

55

Step-by-step explanation:

There are many ways to solve this problem; however, I used the one I believe to be the fastest and easiest, but you can still use a different way.

I solved this by using the fact that the green angle (m<125) and the red angle (x) make a straight line. All straight lines equal 180 degrees; therefore, this line must equal 125+x=180. Then, you can subtract 125 from both sides of the equation. That leaves x=55.

2 - x = x - 8

ayudaaa
porfavor

Answers

Answer:

x=5

Step-by-step explanation:

2 - x = x - 8

- x = x - 8 - 2 (subtract 2 from both sides)

- x = x - 10 (combine like terms)

- 2x = - 10 (subtract x from both sides)

x = 5 (divide each side by -2).

Answer:

x = 5

Step-by-step explanation:

2 - x = x - 8

- x + 2 = x - 8

- x + 2 - 2 = x - 8 - 2

- x = x - 10

- x - x = x - x - 10

- 2x = - 10

- 2x ÷ - 2 = - 10 ÷ - 2

x = 5

Find the value of x.l

Answers

Answer:

The value of x is 28°

Step-by-step explanation:

2x + 1 and 33° together forms 90° angle.

So, we need to find the angle at the 2x + 1.

--> 90° - 33°

= 57°

So, 2x + 1 gives 57°.

So, to find x :-

2x + 1 = 57°

2x = 57 - 1

2x = 56

x = [tex]\frac{56}{2}[/tex]

x = 28

Find the value of x in the following diagram.

Answers

Answer:

x = 3.5

Step-by-step explanation:

By definition, congruent chords are equidistant from the center of a circle. We are given two congruent chords and their distances(the lines perpendicular), meaning those distances must be equal. We set set up an equation to model the situation:

x + 8 = 3x + 1

8 = 2x + 1

2x = 7

x = 3.5
