If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-fifths full?​
dalvyx [7]

Answer:

<em>3/5 of 30 = (3/5)*30</em>

<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5</em>

<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5</em>

<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18</em>

<em>3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.</em>

Giselle pays $220 in advance on her account at the athletic club. Each time she uses the club,
ale4655 [162]

Answer:

y=220-15x

Step-by-step explanation:

Let x represent the number of times Giselle uses the athletic club and y represent money left in account.

We have been given that each time she uses the club,  $15 is deducted from the account. The amount used after using the club after x times would be 15x.

We are also told that Giselle pays $220 in advance on her account at the athletic club.

The money left in account after x uses of athletic club would be money in account initially minus amount used for using the club x times.

y=220-15x

Therefore, our required equation would be y=220-15x.
