11n + 5 = 13n   Subtract 11n from both sides
         5 = 2n    Divide both sides by 2
         \frac{5}{2} = n     Switch the sides to make it easier to read
         n = \frac{5}{2}

Check your answer:

11n + 5 = 13n   Substitute n for \frac{5}{2}
11(\frac{5}{2}) + 5 = 13(\frac{5}{2})   Simplify
\frac{55}{2} + \frac{10}{2} = \frac{65}{2}   Add
\frac{65}{2} = \frac{65}{2}

Find M<1, M<2, M<3, M<4, M<5
Leokris [45]

Answer:

Step-by-step explanation:

m∠2 = 52° [Alternate interior angles]

m∠1 + m∠2 = 180° [Linear pair of angles are supplementary]

m∠1 = 180° - 52°

m∠1 = 128°

m∠3 = 47° [Alternate interior angles]

m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]

m∠5 = 180° - 99°

        = 81°

m∠4 + 47° = 180° [Sum of consecutive interior angles is 180°]

m∠4 = 180° - 47°

m∠4 = 137°

What are the coordinates of the terminal point determined by t=20pi/3?
attashe74 [19]

Answer:

(- 1/2 , √3/2)

Step-by-step explanation:

t=20π/3

t' = 20π/3 - 6π = 2π/3   (120°) ... 2nd quadrant

If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)

OF/OE = - cos 60° = x / 1 =  - 1/2

FE/OE = sin 60° = y/1  = √3/2
