Answer:
1388
Step-by-step explanation:
0.4625
The 2 is rounded to a 3 because 5 rounds up.
0.463
The 6 stays the same because 3 rounds down.
0.46
Now I'm not sure if you're talking about money so if you are, the answer would be
$0.46
If you are talking about the specific cent and only cent, you continue rounding.
The 4 is rounded to a 5 because 6 rounds up.
0.5
$0.05
(4x³+ 13x − 7) − (6x²<span>+ 9x + 2)
Remember that if they don't have the same exponents/bases (x</span>²,x³, etc.), then they cannot be grouped together.
This means that 4x³ and 6x² will be left alone because there are no other x² or x³ in the expression.
So first thing you do is distribute. Don't forget about that - in front of the second parentheses.
(4x³+ 13x − 7) − (6x²+ 9x + 2)
(4x³ + 13x − 7) + (−6x² - 9x - 2)
4x³ - 6x² + (13x - 7) + (-9x - 2)
4x³ - 6x² + 4x (- 7) + (- 2)
4x³ - 6x² + 4x - 9
So the answer is:
C. <span>4x3− 6x2+ 4x − 9</span>
A is 32 because
2a=64
a=64/2
Max's deck also has 40 blue cards, and for every 5 blue cards in his deck there are 9 red cards. His blue cards can be divided exactly into 8 groups (8 times 5 is 40), so he should also be able to divide his red cards into exactly 8 groups of 9 cards each. So there are 72 red cards in his deck (8 times 9 is 72).
