Like it is stated, combine like terms. In case you don't know what that means, then the question is essentially asking for you to add/subtract etc. expressions from each other that have the same variable.

Given: -\frac{2}{3} a + \frac{5}{6}a - \frac{1}{6} \\\\

Note: -\frac{2}{3}a = -\frac{4}{6}a

-\frac{4}{6}a + \frac{5}{6}a - \frac{1}{6} = \\\\\frac{1}{6}a - \frac{1}{6} \\

So, \frac{1}{6}a - \frac{1}{6} is the new and equivalent expression. We cannot do anything further because there are no like terms.

Answer:

-1/6(-a+1)

Step-by-step explanation:

1. Factor out -1/6 from the expression: -1/6(4a-5a+1)

2. Collect the terms: -1/6(-a+1)

Final Answer: -1/6(-a+1)

A wildlife service wanted to estimate the number of alligators in a river so they tagged 90 alligators and released them back in
lilavasa [31]
You can solve this with a proportion. If you know that 23 tagged alligators were in a 200 alligator sample, there are 90 tagged alligators in the entire river. Written otherwise:

23/200 = 90/x    

and solve for x:

x = 782.608...

So the "best estimate" would be around 783 alligators. Hope that helps! If you liked this answer please rate it as brainliest!! thank you!!!

PLEASE HELP!! DUE SOON :( #40

Answer:

Types of polygon

Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon.

Regular and irregular polygons

Interior angles of polygons

To find the sum of interior angles in a polygon divide the polygon into triangles.

Irregular pentagons

The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.

Example

Calculate the sum of interior angles in a pentagon.

A pentagon contains 3 triangles. The sum of the interior angles is:

180 * 3 = 540

The number of triangles in each polygon is two less than the number of sides.

The formula for calculating the sum of interior angles is:

(n - 2) * 180  (where n is the number of sides)

What is the span of the roof? A. 4 ft B. 12 ft C. 18 ft D. 24 ft
RoseWind [281]

Answer:

  D.  24 ft

Step-by-step explanation:

The slope of 1/3 means the rise is 1/3 the run for each half of the span. The rise is shown as 4 ft, so the half-span is 3·4 ft = 12 ft.

The span of the roof is 24 ft.
