Next time, Shay, please include the instructions. I'm assuming that our job here is to determine the largest # of boxes of darts that can be purchased.
Shirt cost + x(box of darts cost) = Initial amount
$56 + x($6/box) = $80
Then 56 + 6x = 80, or 6x= 24, or x = 4. He can buy 4 boxes of darts.
The correct answer is 58/7 (decimal: 8,28....)
I think B gives the best estimate and exact product because
1). 5.9 x 8.28 is very similar to 6 x 8 which equals 48.
and
2. 5.9 x 8.28 = 48.852.
Hopefully that made sense. :)
The expression (−81)(−9) will give the value of 729.
<u>Step-by-step explanation:</u>
The given expression is (−81)(−9)
.
The both numbers in the expression are negative numbers and they are given inside the brackets.
This means that, the negative numbers must be multiplied to get a final value.
<u>The rules in multiplication are :</u>
- Positive number × Positive number = positive number
- Negative number × Positive number = negative number
- Positive number × Negative number = negative number
- Negative number × Negative number = positive number
From the rules, it can be determined that the result of any two negative numbers will be a positive number.
So, eliminate option A) and B) because they have negative sign.
The expression (−81)(−9) = -81 × -9
⇒ 729.
Therefore, the option C) and D) are not in match with 729. None of the options are not the value of the given expression (−81)(−9).
