The solution of the equation 2d - 6 = 5 is _____.

Answers

If you would like to solve the equation 2 * d - 6 = 5, you can do this using the following steps:

2 * d - 6 = 5
2 * d = 5 + 6
2 * d = 11 /2
d = 11/2
d = 5 1/2

The correct result would be 5 1/2.

$2d-6=5\n\nAdd\ 6\ on\ both\ sides.\n\n2d=11\n\nDivide\ by\ 2\ on\ both\ sides.\n\nd= (11)/(2)\n\nd=5(1)/(2)$

$\sf\ Answer:\ {\boxed{d=5(1)/(2)}}$

Round 24824.939838 to the nearest thousand.

Answers

Answer:

25,000

Step-by-step explanation:

24,824 is read as twenty-four thousand, eight-hundred twenty-four

the first 2 is in the ten thousands position

the first 4 is in the thousands position

the 8 is in the hundreds position

the second 2 is in the tens position

the second 4 is in the ones position

If you want to round to the nearest thousand then you must refer to the digit in the hundreds position - if this number is greater than or equal to 5 then the number in the thousands place is increased by 4; otherwise the number in the thousands place remains the same

So in this case with 24,824 the '8' is greater than 5; therefore, the 4 becomes a 5 and the answer is 25,000

$2,252.79
$2,642.77
$2,715.77

Answers

Answer:

The new balance of her saving account is $ 2252.79

Step-by-step explanation:

Given : Ellen Saver went to her bank. She had a balance of $2,447.67 in her savings account. She withdrew $231.49 and the teller credited her account with $36.61.

We have to determine the new account balance.

Since inital balance is $ 2,447.67

ans she withdraw $ 231.49 that is taken ouu so we subtract from inital balance.

thus, balance after withdraw is (2447.67 - 231.49) = $ 2216.18

Now, the teller credited the account with $ 36.61 that is $ 36.61 is added to the account.

So, new balance after credit $ 36.61 is $(2216.18 + 36.61) = $ 2252.79

Thus, the new balance of her saving account is $ 2252.79

Given:

Beginning Balance: 2,447.67
Less: Withdrawal 231.49
Total 2,216.18
Add: Credit to acct 36.61
Ending Balance 2,252.79

The new balance is $2,252.79
