**Answer:**

x=6.1

y=12.6

**Step-by-step explanation:**

x/14 = sin26°

x = 14sin26° = 6.1 (nearest tenth)

y = √(14^2 - x^2) = 12.6 (nearest tenth)

**Answer:**

x = 5

**Step-by-step explanation:**

The total cost C (in dollars) to participate in a ski club is given by the literal equation :

C=85x+60C=85x+60

Where x is the number of ski trips you take.

1. When C = 315 ;substituting the value of C in the above equation.

315=85x+60315=85x+60

=> 85x=315-6085x=315−60

=> 85x=25585x=255

x = 3 trips.

2. When C = 485

485=85x+60485=85x+60

=> 85x=485-6085x=485−60

=> 85x=42585x=425

x = 5 trips.
