Make m the subject of the formula m/v - t/b = m-t/r
RoseWind [281]

Answer:

m =   - \frac{ \frac{t}{b} +  \frac{t}{r}  }{1 -  \frac{1}{v} }

Step-by-step explanation:

\frac{m}{v}  -  \frac{t}{b}  = m -  \frac{t}{r}  \\  \frac{m}{v}  -  \frac{t}{b}  +  \frac{t}{r} = m \\  -  \frac{t}{b}   +  \frac{t}{r}  = m -   \frac{m}{v}  \\  -  \frac{t}{b}  +  \frac{t}{r}  = m(1 -  \frac{1}{v} ) \\    - \frac{t}{b}  +  \frac{t}{r}  =  \frac{m( 1 -  \frac{1}{v})  }{(1 -  \frac{1}{v}) }  \\    - \frac{ \frac{t}{b}  +  \frac{t}{r} }{1 - ( \frac{1}{v} ) }  = m

I need help thank you!<br> (7x + 14)<br> (15x - 4)
sergey [27]

Answer:

(7x + 14)° = 84°

(15x - 4)° = 146°

Step-by-step explanation:

62° + (7x + 14)° = (15x - 4)°

62° +7x + 14 = 15x - 4

15x - 7x = 62 + 14 + 4

8x = 80

x = 10

Therefore, exterior angle (15x - 4)° = 146°

                interior angle (7x + 14)° = 84°
