Answer:

195 Trees

Step-by-step explanation:

2/3 is just 2 of 3 parts

2 parts of the trees is 130,

so divide 130 by 2, and that's 65.

Since you know 65 + 65 is the same as 2 out of 3

Then just add 65 one more time to equal 195.

Since, 65*3 is the same as saying 1 * 3 parts

130 is equal to 2/3, so 195 is equal to 3/3.

195.

set this up as a proportion with 2/3 = 130/x
130 x 3 = 390
390 / 2 = 195

Bill can hit a bucket of 323 gold balls in 17 hours.
yanalaym [24]
It is important to clearly understand all the important information's already given in the question. Based on those details the answer to the question can be easily determined.
In 17 hours the number of golf balls hit by Bill = 323
Then
In 1 hour the number of golf balls hit by Bill = (323/17) * 1
                                                                     = 19
So
The number of golf balls hit by Bill in 23 hours = 23 * 19
                                                                          = 437
So 437 balls will be hit by Bill in 23 hours. I hope the procedure is clear enough for you to understand. This procedure will help you to solve similar problems in future without requiring any outside help.

What is the solution of 2m=-6n-5 when n=1,2,3
Travka [436]

Answer:


Step-by-step explanation:

Simplifying

2m + -6n + 5n + 3m = 0


Reorder the terms:

2m + 3m + -6n + 5n = 0


Combine like terms: 2m + 3m = 5m

5m + -6n + 5n = 0


Combine like terms: -6n + 5n = -1n

5m + -1n = 0


Solving

5m + -1n = 0


Solving for variable 'm'.


Move all terms containing m to the left, all other terms to the right.


Add 'n' to each side of the equation.

5m + -1n + n = 0 + n


Combine like terms: -1n + n = 0

5m + 0 = 0 + n

5m = 0 + n

Remove the zero:

5m = n


Divide each side by '5'.

m = 0.2n


Simplifying

m = 0.2n

The lengths of the sides of a triangle are consecutive odd integers. If the perimeter is 1 less than 4 times the shortest side,
Lubov Fominskaja [6]
Let the shortest side be x.  Then the other two sides will be x+1 and x+2.

Perimeter = P = sum of the lengths of all three sides = x  +  (x+1) + (x+2) 

This perimeter = 4x -1 (1 less than 4 times the shortest side).

Then x + x + 1 + x + 2 = 4x - 1
      or:        3x + 3         = 4x -1                 Subtr. 3x from both sides:
                                                                  3 = x - 1

x=4, x+1=5, and x+2=6

The 3 sides have lengths 4, 5 and 6.

Please select all the correct choices​
sineoko [7]

The correct choices based on the Segment Addition Postulate are <u>C. WX + XY + YZ = WZ</u> and <u>E. WY + YZ = WZ</u>.

<h3>What is a segment addition postulate?</h3>

A segment addition postulate is a part of a segment line that consists of two endpoints and all of the points between them.

For example, the segment addition postulate of line segment, AC will be defined as the sum of the lengths of the segments, AB and BC being equal to the total length AC.

<h3 />

The possible addition postulates that can be created from WZ are:

WZ = WX + XY + YZ

WZ = WY + YZ

WZ = WX + XZ

Thus, the correct choices of the segment addition postulate are <u>Options C and E</u>.
