Step-by-step explanation:

Average movie ticket prices in the united states are, in general, lower than other countries. It would cost in $77.87 to buy three tickets in Japan plus two tickets in Switzerland. Three tickets in Switzerland plus two tickets in Japan would cost $73.83. How much does an average movie ticket cost in each of these countries?  

Let ticket in japan cost x

Let ticket in Switzerland cost y  

3x+2y=77.87 1

3y+2x=73.832  

Subtract the equations  

x-y= 4.04 ---4

3y+2x=73.835

If sin y = 7/q and tan y= 7/r then the value of cos y is \frac{r}{q}

Step-by-step explanation:

Solution:

The values of sin y and tan y are given as 7/q and 7/r respectively.

We know the relationship between tan cos and sin which is

 --- equation 1

Since we already know the values of sin y and tan y we can easily find the value of cos y by substituting the values in eq1

Taking cos y to the other side of the equal to sign we get

Hence the value of cos y is \frac{r}{q}
