Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month.

Super Fit charges a one-time registration fee of $150, and membership is $10 a month.

(a) Write a expression to represent the membership cost of Platinum Gym for x months.

Let x = months

20x + 60 is your expression

(b) Write an expression to represent the membership cost of Super Fit for x months

Let x = months

10x + 150 is your expression

(c) You are solving for both one month and twelve months of membership.

<u>One month:</u> Plug in 1 for x.

20(1) + 60 = 20 + 60 = 80

10(1) + 150 = 10 + 150 = 160

Platinum Gym is cheaper overall for one month by $80

<u>One year:</u> There are twelve months in a year. Plug in 12 for x.

20(12) + 60 = 240 + 60 = 300

10(12) + 150 = 120 + 150 = 270

Super Fit is cheaper than Platinum Gym overall for one year by $30

(d) Set the two expression equal to each other.

20x + 60 = 10x + 150

Isolate the x. Subtract 10x and 60 from both sides

20x (-10x) + 60 (-60) = 10x (-10x) + 150 (-60)

20x - 10x = 150 - 60

Simplify

20x - 10x = 150 - 60

10x = 90

Isolate the x. Divide 10 from both sides

10x/10 = 90/10

x = 9

It takes 9 months for the cost to be the same.

(e) It really depends on how long you want to work out at a gym. If you are working out for less than a year, than Platinum Gym is the better choice. If more than a year, then Super Fit is the better choice.

If you ride a pterodactyl for 3 hours at 10 mph and then ride a stegosaurus for 1 hour at 2 mph, what would be your average spee
g100num [7]

Answer:

8 mph

Step-by-step explanation:

The equation for average speed is:

average\ speed=\frac{total\ distance}{total\ time}

Let's start by finding the distance for each animal:

d=st\\d=3h*10\frac{m}{h}\\d=30m

d=st\\d=1h*2\frac{m}{h}\\d=2m

Now, we can find the average speed:

average \ speed=\frac{30mi+2mi}{3hr+1hr}=\frac{32mi}{4hr}=8\frac{mi}{h}

8 mph
