7x-3=-3+7x i neep help answer this please

Answer:

All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

7x− 3 = − 3 + 7x

Step 1: Simplify both sides of the equation.

7x − 3 = −3 + 7x

7x + −3 = −3 + 7x

7x − 3 = 7x − 3

Step 2: Subtract 7x from both sides.

7x− 3 −7x = 7x −3 −7x

−3 = −3

Step 3: Add 3 to both sides.

−3 + 3 = −3 + 3

0 =  0

garri49 [273]

We can see that two sides of that triangle area equal

so, their corresponding angle will also be equal

now, we know that

sum of all angles in any triangle is always 180

so, we can get equation as

x+100+x=180

now, we can solve for x

2x+100=180

2x=80

x=40

so, option-C..............Answer

What is the measure (in radians) of central angle &amp; in the circle below?
MA_775_DIABLO [31]

Answer:

7pi/6

Step-by-step explanation:

Using the formula for arc length in radians, we get:

  1. 14pi = 12(theta)
  2. theta = 7pi/6 [divide both sides by 12]
