Diano4ka-milaya [45]
Sorry that is wrong, you distribute the 2 to the h and the 8 so it would be 2h-16-h. that would be h-16 on the left side,

Ethan sold some watches at $14 each and 20 bookmarks at $1.50 each. Roy sold the same number of watches at $13.50 each and 20 bo
-Dominant- [34]

[<Answer>] (1):
<em>Heyy there, it's Avery. And I'm here to help! :)

</em>----------------------------------------------------------------------------------------------------------[<The Explanation>]:

Let x= number of watches sold

<em>Ethan= x(14) + (20)(1.50)</em>

<em>Roy = x(13.50) + (20)(1.80)</em>

Since they collected the same amount of money:

<em>14x + (20)(1.50) = 13.50x + (20)(1.80)</em>

Combine like terms:

<em>14x - 13.50x = (20)(1.80) - (20)(1.50)</em>

<em>0.50x = 36 - 30</em>

<em>0.50x = 6</em>

<em>x = 6/0.50</em>

<em>x= 12</em>

Ethan sold 12 watches. And also Roy.
Andddd...We're done! :D

<em>Hope this helps and if it's wrong, you can't sue me! :D</em>

Bye! Hope this works for you :)

Have a nice day! - Avery <3

On a road trip, you stop to get gas when there is 1 4of a tank of gas left. You get the tank filled and this takes 12 gallons of
dimulka [17.4K]

Answer: 16 gallons

Step-by-step explanation:

Since we are given the information that 1/4 of the gas is left, it simply means that (1 - 1/4) = 3/4 has been used.

The tank was filled and this was 12 gallons of gas.

Let the gas that the tank hold be represented by x. Therefore,

3/4 of x = 12

3/4 × x = 12

0.75x = 12

x = 12/0.75

x = 16

The tank holds 16 gallons of gas.
