\bf 1-\cfrac{tan(\theta )cos(\theta )}{csc(\theta )}\implies 1-\cfrac{\frac{sin(\theta )}{cos(\theta )}cos(\theta )}{csc(\theta )}
\\\\\\
\boxed{1-\cfrac{\frac{sin(\theta )}{\underline{cos(\theta )}}\cdot \underline{cos(\theta )}}{\frac{1}{sin(\theta )}}\implies 1-\cfrac{sin(\theta )}{\frac{1}{sin(\theta )}}}\implies 1-sin(\theta )sin(\theta )

3 (1 - 2v) - V = -1 (3y + 1)
Dominik [7]

Answer: v =  3 /7 y +  4 /7

Step-by-step explanation:

Step 1: Add -3 to both sides.

−7v+3+−3=−3y−1+−3

−7v=−3y−4

Step 2: Divide both sides by -7.

−7v /−7  =  −3y−4 /-7

v= 3 /7 y +  4 /7

16 emails to 6 text messages- 10 emails to 4 text messages proportional or not
Pavel [41]

Given:

16 emails to 6 text messages- 10 emails to 4 text messages

To find:

Whether 16 emails to 6 text messages- 10 emails to 4 text messages proportional or not.

Solution:

Check the ratio of emails to text. If the ratios are equal then the relation is proportional.

16 emails to 6 text messages.

\dfrac{Emails}{Text}=\dfrac{16}{6}

\dfrac{Emails}{Text}=\dfrac{8}{3}

\dfrac{Emails}{Text}=8:3

10 emails to 4 text messages.

\dfrac{Emails}{Text}=\dfrac{10}{4}

\dfrac{Emails}{Text}=\dfrac{5}{2}

\dfrac{Emails}{Text}=5:2

Since \dfrac{8}{3}\neq \dfrac{5}{2} or 8:3\neq 5:2, therefore, it is not proportional.
