Step-by-step explanation:
the box is
9 in × 3.5 in × 4.5 in = 141.75 in³
each block is
0.5 in × 0.5 in × 0.5 in = 0.125 in³ (1/8 in³)
so, we can fit
141.75 / 0.125 = 1134
blocks into the box.
and they fit neatly, as the dimensions of the box and the cubes allow a tight packing without any empty left over space in the box.
You are close, but it is not the correct answer.
1 + 2k = 5k + 7
First, since we are trying to get the variable by itself, we need to move all things to one side. Let's subtract 1 from each side.

Second, we can now subtract (7 - 1) to get 6. Let's add that into our problem and then subtract 5 from each side, still trying to get the variable by itself.

Third, subtract (2k - 5k) to get -3k. Hint the negative symbol now. If the problem were switched the other way, it would still be a positive.

Fourth, we can now divide each side by -3. This results in a fraction and also getting the variable by itself on one side of the problem. Remember the negative sign in front of the fraction since (-3) carried it.
Fifth, this is our last step. We need to simplify the fraction. Since out fraction is 6/3, which number multiples by 3 to get the answer of 6? The answer is 2, since (3 × 2 = 6). Don't forget the negative!

Answer:
The domain of a function is the set of values that can be used for x.
Here, x represents the number of tacos.
He can order no taco, so x = 0.
He can order 1 taco, where x = 1.
He can order 2 tacos, so x = 2.
He cannot order a fraction of a taco, so x cannot be a mixed numeral.
He can order as many tacos as he wants, so x can be any whole number, 0 to infinity.
The domain is all whole numbers.
Answer:
The total refund that the museum owes the 11:00am group is $28.50
Step-by-step explanation:
$12.25*38 = $465.50
$11.50*38 = $437
Subtract: $465.50 - $437 = $28.50
X is radical 3
y is 2 radical 3
