Step-by-step explanation:

4y³ - 5x³ - 1 - 4y³ - 6 + 7 + 5y³

= -5x³ + (4y³ - 4y³ + 5y³) + (- 1 - 6 + 7)

= -5x³ + (0 + 5y³) + (- 7 + 7)

= -5x³ + 5y³

Naddik [55]

Answer:

Chelsey can be a member of the fitness club for <u>10</u> months.

Step-by-step explanation:

Given:

Chelsey wants to join a fitness club.

The fitness club charges an initial membership fee of $55 and a monthly fee of $19.50.

She has $250 to spend on a membership at the fitness club.

Now, to find the number of months Chelsey can be a member of the fitness club.

Let the number of months Chelsey can be a member of the fitness club be x.

Monthly fee = $19.50.

Membership fee = $55.

Now, to get the number of months Chelsey can be a member of the fitness club we write and solve an equation:

55+19.50(x)=250.

55+19.50\times x=250\\\\55+19.50x=250

<em>Subtracting both sides by 55 we get:</em>

19.50x=195

<em>Dividing both sides by 19.50 we get:</em>

x=10.

Therefore, Chelsey can be a member of the fitness club for 10 months.
