Alice cycles to Carla's house at 12 mph and returns by car at 36 mph. If the round trip takes 1 hour, how far away from Carla do

Eduardwww [97]

Answer:

Alice lives 9 miles far away from Carla.

Step-by-step explanation:

Given:

Alice cycles to Carla's house at 12 mph and returns by car at 36 mph.

If the round trip takes 1 hour.

Now, to find the distance from Carla to Alice house.

So, let the distance between the houses of Carla and Alice be $x$ .

Now, we solve by using the formula:

Distance/speed = time

Alice cycles to Carla house = $\frac{x}{12}$

And return by car = $\frac{x}{36}$

Time taken for round trip = 1 hour.

Adding both the distance to get the value of x:

$\frac{x}{12}+\frac{x}{36}=1$

$=\frac{3x+x}{36}=1$

$=\frac{4x}{36}=1$

Dividing both sides by 4 we get:

$x=9$

Therefore, Alice lives 9 miles far away from Carla.

Hayden brought 18 new trading cards. Three-fourths of the new cards are baseball cards. How many baseball cards did Hayden buy

marshall27 [118]

He bought 36 baseball cards. Since 3/4 of the 48 cards are baseball cards, you need to find 75% of 48, which is 36 cards.

I’m I right? If not change it for me

The first and third are correct. They are equal.

The second is incorrect. This is because 1800 meters = 1.8 km (not 18 km). The answer you should have is a "less than sign" because 1.8 km is smaller than 18 km.

To go from meters to kilometers, you move the decimal point 3 spots to the left. This is the same as dividing by 1000.

To go from kilometers to meters, you move the decimal point 3 spots to the right. This is the same as multiplying by 1000.

First part 3x+(-5)=19 you need to remove parenthesis move the constant -5 to the right to have 3x=19+5 then add those to get 3x=24 then divide to get x=8
