slavikrds [6]

Answer:

x = 33

Step-by-step explanation:

Given

Students = 28

Brownies = 23

Brownies = 2\ per\ student

Required

Determine the number of brownies left

If:

Brownies = 2\ per\ student

and there are 28 students

Then:

Total\ Brownies = 2 * 28

Total\ Brownies = 56

To determine the number of brownies left, we have:

Total\ Brownies = Brownies\ Made + Brownies\ Left

56 = 23 + x

Reorder

x + 23 = 56

Collect Like Terms

x = 56 - 23

x = 33

<em>Hence, there are 33 brownies left</em>

Answer:

V≈653

Step-by-step explanation:

In order to find the volume of a cylinder, you use the formula V=πr2h. In this case, the filled-in formula would be V=3.14*4*4*13. This equals 653.45. In your answer, you need to round to the nearest whole number. In this case, round down to 653. That is your answer. Hope this helps :)

I got stuck on this question.<br> Use long division to solve
Phantasy [73]

Answer:

  5x² +19x +76 +310/(x-4)

Step-by-step explanation:

The process is straightforward. Find the quotient term, multiply it by the divisor and subtract from the dividend to get the new dividend. Repeat until the dividend is a constant (lower-degree than the divisor).

The tricky part with this one is realizing that there is no x-term in the original dividend, so that term needs to be added with a 0 coefficient. The rather large remainder is also unexpected, but that's the way this problem unfolds.

__

Unlike numerical long division, polynomial long division is simplified by the fact that the quotient term is the ratio of the highest-degree terms of the dividend and divisor. Here, the first quotient term is (5x^3)/(x) = 5x^2.

volume=160 times 32
volume=5120


volume is 5120 cubic centimeters or
5120 cm^3
