2. A book with a green sticker costs $2 less than half the price of a

Damm [24]

For this case we can propose an equation that will allow us to find the price of one of the books knowing the price of the other.

x: Let the variable that represents the price of the book with a green sticker

y: Let the variable that represents the price of the book with a yellow sticker

According to the statement we have:

$x = \frac {y} {2} -2\\$

$y=2(x+2)$

Finally, we can substitute the price of one of the books and clear the value of the other as the case may be.

Answer:

$x = \frac {y} {2} -2$

The Amount of sales tax on a new car varies directly to the purchase price of the car. On a 25,000 car, sales tax is 1,750. What

Gekata [30.6K]

Answer:

50,000

Step-by-step explanation:

1st car had $1,750 tax

2nd car has $3,500 tax

1750(2) = 3500

so your tax doubled so the price must be doubled.

The car is $50,000

Algebraically using direct variation:

t = kp where t=tax, p = purchase price,

and k is constant of variation

1750 = 25000k

k = 1750/25000

k = 0.07

Your equation is: t = 0.07p

3500 = 0.07p

p = 3500/0.07

p = $50,000

Alonzo takes 12 minutes to run 6 times around a 400-meter track. Assuming he runs at a constant speed, how long does he take to

snow_lady [41]

Answer:

5 minutes to run 1 kilometer

Step-by-step explanation:

Alonzo takes 12 minutes to run 6 times around a 400-meter track.

6 times around a 400 m track

400 * 6 = 2400 meters

It take 12 minutes to run 2400 meters

2400 meters = 2400/1000 = 2.4km

distance = 2.4 km and time = 12 minutes

Now we find our constant speed

$Distance = speed * time$

2.4 = speed * 12

divide by 12 on both sides

speed = 0.2

so speed is 0.2 km per minute

Now we find out time when distance = 1km

Distance = speed * time

1 = 0.2 * t

divide by 0.2 on both sides

5 = t

So it take 5 minutes to run 1 kilometer
