Answer:
-11, -10, -9
Step-by-step explanation:
The middle one is their average, -30/3 = -10. The three integers are -11, -10, -9.
_____
I like to work "consecutive integer" problems using the average value of the integers involved. The average of <u>two</u> consecutive integers is 1/2 more than the small one, and 1/2 less than the large one, for example. Here, there are <u>three</u> consecutive integers, so their average is the middle one.
If you want to write that using an equation, you can let x represent the middle integer. Then the sum is ...
(x -1) +(x) + (x+1) = 3x = -30
x = -30/3 = -10 . . . . . the same average we computed above.
x -1 = -11 . . . . . the smaller of the other two integers
x +1 = -9 . . . . . the larger of the other two integers
Answer:
It is D.
Step-by-step explanation:
x ≤ 3 or x ≥ –1
Answer:
$300.64
Step-by-step explanation:
Step one:
Given data
Jennifer had $256.86
She made a deposit of $43.78
Required
The total amount in the account
Step two:
To get the balance, we need to sum the previous amount with the deposited amount
Total= 256.86 +43.78
Total=$300.64
The balance is $300.64
14 53/100
14 212/400 are both equivalent
The answer to 4+4+4+4+13,456= is 13,472
