Rachel withdraws $18 from the bank account once each day for six days. What integer represents the change in the amount in the account? Use a pencil and paper. Find the integer that would represent the change in the amount in the account if Rachel deposits $18 into her bank account once each day for six days. Explain the difference between the integer for the withdrawals and the integer for the deposits.

-108

108

Step-by-step explanation:

Since it is withdrawing, we are taking away -$18 every day for 6 days.

(-18)*6 = -108

Since it is deposits, we are adding to the amount in her account, +$18 for 6 days.

18*6 = 108

The difference is that one is taking away and one is adding each day, resulting in negative or positive change.

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
