Solve for c.<br><br> 3 − 7c − 20c = 7(–7c − 19) + 14c<br><br> c =

Kazeer [188]

Answer:

$\boxed{c = -17}$

Step-by-step explanation:

$= > 3 - 7c - 20c = 7( - 7c - 19) + 14c \\ \\ = > 3 - 27c = ( - 7c \times 7) - (7 \times 19) + 14c \\ \\ = > 3 - 27c = - 49c - 133 + 14c \\ \\ = > 3 - 27c = - 35c - 133 \\ \\ = > 3 - 27c + 35c = - 133 \\ \\ = > 3 + 8c = - 133 \\ \\ = > 8c = - 133 - 3 \\ \\ = > 8c = - 136 \\ \\ = > c = - \frac{136}{8} \\ \\ = > c = - 17$

Transforme em π rad :<br>a)30°<br>b)40°<br>c)45°<br>d) 50°

Roman55 [17]

Answers:

a) $\frac{1}{6} \pi rad$

b) $\frac{2}{9} \pi rad$

c) $\frac{1}{4} \pi rad$

d) $\frac{5}{18} \pi rad$

Step-by-step explanation:

In this case we are dealing with angles, which can be expressed in degrees ( $\°$ ) or radians ( $rad$ ).

Now, before making the conversions we have to know the equivalence between degrees and radians:

$180 \°=1 \pi rad$

Taking this information into account, let's begin with the answers:

a) $30\° \frac{1 \pi rad}{180 \°}=\frac{1}{6} \pi rad$

b) $40\° \frac{1 \pi rad}{180 \°}=\frac{2}{9} \pi rad$

c) $40\° \frac{1 \pi rad}{180 \°}=\frac{1}{4} \pi rad$

d) $50\° \frac{1 \pi rad}{180 \°}=\frac{5}{18} \pi rad$
