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:

$x=60^{\circ}$

Step-by-step explanation:

The angle formed by $48+x$ and the angle marked as $72^{\circ}$ are co-interior angles and therefore must be supplementary (add up to 180 degrees).

Therefore, we have:

$48+x+72=180,\\x+120=180,\\x=\boxed{60^{\circ}}$
