Bunny hill ski resort charges $35 for ski rental and $10 an hour to ski. black diamond ski resort charges $40 for ski rental and $5 an hour to ski. create an equation to determine at what point the cost of both ski slopes is the same. 10x − 35 = 5x − 40 10x + 35 = 5x + 40 10x + 40 = 5x + 35 10x − 40 = 5x − 35

The equation is

Step-by-step explanation:

Let

x --> the charge per hour to ski  

y ---> the total charge for ski

we know that

Bunny Hill Ski Resort

----> equation A

Black Diamond Ski Resort

----> equation B

equate equation A and equation B

solve for x

Find the value of y

therefore

At point (1,45) the cost of both ski resort is the same

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
