Hello,

it's an equilateral triangle, all sides and all angles are the same.

4 = 2y + 6

-2y = 6 - 4

-2y = 2

y = 2 : 2

y = 1 or -1

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.
