Answer:

x= \frac{-7}{2}

Step-by-step explanation:

9x-2=11x+5

-9x       -9x

-2=2x+5

-5       -5

-7=2x

\frac{-7}{2} = \frac{2x}{2}

\frac{-7}{2}=x

Answer: X = -7/2

Step-by-step explanation: 1. Write out your equation you wanna solve

9X - 2 = 11X + 5

2. Subtract -9X on both sides

9X (-9X) -2 = 11X (-9X) + 5 = -2 = 2X + 5.

3. Subtract -5 off of both sides

-2 (-5) = 2X + 5 (-5) = -7 = 2X (<-- Make your -2 a +2)

4. Divide -7 = 2X by 2!!!

-7/2 = 2X/2

5. Write your answer

X = -7/2

Good luck and I hope this helps you out!! Byeee!

If m∠A =91° and m∠B = 40°, find m∠1.
marusya05 [52]

Answer:

m∠1 is calculated as 49°.

Step-by-step explanation:

Consider the angles are the interior angles of a triangle.

                      m∠A =91°

                      m∠B = 40°

                      m∠1  = ?

We know that the sum of interior angles of a triangle is 180°. So,

                          m∠A + m∠B + m∠1 = 180°

                      or, m∠1 = 180°- m∠A - m∠B

                      or, m∠1 = 180°- 91° - 40°

                      or, m∠1 = 49°

Hence, m∠1 = 49°.
