6 0

Step-by-step explanation:

2 hours -----> $12.50

1 hour -----> $12.50/2 = $6.25

Now, putting it in the form of y = kx,

For 1 hour -----> $6.25 = K×1 (General equation)

Similarly,

For 2 hours -----> $12.50 = K×2

For 5 hours -----> $31.25 = K×5

Myesha finds some nickels and quarters under the couch cushions. How many coins does she have if she has 6 nickels and 12 quarte
Advocard [28]

If Myesha found 6 nickels and 12 quarters under her cushion, this means that she has a total of 18 coins.

<h3>What is an equation?</h3>

An equation is an expression used to show the relationship between two or more variables and numbers.

Let x represent the number of nickels and y represent the number of quarters. There are 2 cups in 1 pint. Hence:

If she has 6 nickels and 12 quarters:

Number of coins = 12 + 6  = 18

If she has x nickels and y quarters:

Number of coins = x + y  

If Myesha has 6 nickels and 12 quarters, this means that she has 18 coins.

Iron Man Training While training for an iron man competition, Tony bikes for 60 miles and runs for 15 miles. If his bikes speed
ivolga24 [154]

Answer:

<u>Tony biked 1 hour 40 minutes and run 3 hours 20 minutes.</u>

Step-by-step explanation:

How long did Tony speed on his bike?

Let s to be Tony's running speed, then 8s is Tony's biking speed

Let's recall that Time = Distance/Speed

Bike time + Running time = 5 hrs

Replacing with the real values, we have:

60/8s + 15/s = 5

8s as Lowest Common Denominator

60 + 8 * 15 = 5 * 8s

60 + 120 = 40s

-40s = -180

s = -180-40

s = 4.5 ⇒ 8s = 36

Tony run at 4.5 mph and biked at 36 mph

Now, we can calculate the time, this way:

Bike time = Bike distance/Bike speed

Replacing with the real values, we have:

Bike time = 60/36

Bike time = 5/3 (Dividing by 12)

5/3 hours * 60 = 100 minutes or 1 hour 40 minutes

Running time = 5 hours - 1 hour 40 minutes = 3 hours 20 minutes

<u>Tony biked 1 hour 40 minutes and run 3 hours 20 minutes.</u>
