As parallel sides

\\ \rm\longmapsto 2x+90=180

\\ \rm\longmapsto 2x=90

\\ \rm\longmapsto x=90/2=45

Now

\\ \rm\longmapsto 2x+3y+6y+90=360

\\ \rm\longmapsto 9y+180=360

\\ \rm\longmapsto 9y=180

\\ \rm\longmapsto y=20

Answer:

2x + 90 = 180 \\ 2x = 90 \\ x =  \frac{90}{2}  = 45. \\ now \\  \\ 2x + 3y + 6y + 90 = 360 \\ 9y + 180 = 360 \\ 9y = 180 \\ y = 20.

You plan to go skiing this weekend in Tennessee. The ski resort charges $18.50 per hour in addition to a $100 deposit to rent sk
Rina8888 [55]

Answer:

Part a) y=18.50x+100

Part b) The total cost is \$220.25

Part c) see the explanation

Step-by-step explanation:

Part a) Write a linear equation to represent this situation

Define the variables

Let

x ----> the number of hours

y ----> the total cost in dollars

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope or the unit rate

b is the y-intercept or initial value (value of y when the value of x is equal to zero)

In this problem we have that

The unit rate or slope is equal to

m=\$18.50\ per\ hour

The y-intercept or initial value is equal to

b=\$100

substitute

y=18.50x+100

Part b) Use the equation to find the total cost to rent skis from 8:30 am to 3:00 pm

Remember that

3:00 pm=15:00

so

from 8:30 am to 3:00 pm, the total hours is equal to

15:00 -8:30=6:30=6.5 h

For x=6.5 h

substitute in the linear equation and solve for y

y=18.50(6.5)+100\\y=\$220.25

Part c) What does your answer mean in context of the problem?

we have that

y=220.25

That means -----> The total cost to rent skis for 6.5 hours is equal to $220.25
