Answer: 1st # n=35

2nd # n+2=37

Step-by-step explanation:

n= 1st #

n+2= 2nd #

n+n+2=72

2n+2=72 ( combine like terms)

2n+2-2=72-2

2n=70

2n/2=72/2

n=35

Answer:

Step-by-step explanation:

x + x + 2 = 72

2x = 70

x = 35

35 + 2 = 37

Answer:

r = 8/3w − 15

Step-by-step explanation:

Let's solve for r.

8w−3r=45

Step 1: Add -8w to both sides.

−3r+8w+−8w=45+−8w

−3r=−8w+45

Step 2: Divide both sides by -3.

−3r/−3 = −8w+45/−3

Answer:

Step-by-step explanation:

The measure of the ​angles are 51° and 39°.

When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

Given:

Two pieces of wood are cut to form complementary angles.

One angle needs to be (2x +23) and the other angle needs to be (3x +27).

We have to find the measure of the larger angle?.

According to given question we have

Two angles are complementary when their sum is equal to 90°.

So, ( 2x + 23 ) + ( 3x + 27 ) = 90°

5x + 50° = 90°

5x=40°

x = 8°

Putting value of x in the angles given :

( 2x + 23 )° = 2(8°) + 23° = 39°.

( 3x +27 )° = 3(8°) +27° = 51°.

Therefore, the measure of the ​angles are 51° and 39°.

Answer:

solid shapes

Step-by-step explanation:

solid shapes are formed from two or more plane shapes

When two or more plane shapes are combined, the shape formed is called a composite shape.

A composite shape is created by merging or overlapping different geometric figures. This can include combining polygons, such as triangles, rectangles, or circles, to form a more complex shape. The resulting composite shape retains the characteristics of its individual components but takes on a new form with unique properties and attributes.

Composite shapes can have irregular or regular outlines, and their areas and perimeters can be determined by calculating the sum of the areas and perimeters of the constituent shapes.

Therefore, when two or more plane shapes are combined, the shape formed is called a composite shape.

Answer:

B. 9

Step-by-step explanation:

So when solving a question like this, you may try to find what 3⁴ is and what 3² is and divide, but there is a much easier way to do this. Remember:

[tex]\frac{a^{m}}{a^{n}}=a^{m-n}[/tex]

This can be used to find [tex]\frac{3^{4}}{3^{2}}[/tex] without finding what 3⁴ is. This is how we would do it:

[tex]\frac{3^{4}}{3^{2}}=3^{4-2}=3^{2}=9[/tex]

And now we get the solution, 9, which is answer choice B.

Using the segment addition postulate, the numerical length of TV is: 9 units.

According to the segment addition postulate, if U lies between line segment TV, therefore:

TV = TU + UV

Plug in the values:

3x + 6 = 4 + 5x

Solve for x

3x - 5x = 4 - 6

-2x = -2

x = 1

TV = 3x + 6 = 3(1) + 6

TV = 9 units

¿Por qué la línea es el rey de la jungla?

Answer:

Simplifying x + 6.7 = -9.7 Reorder the terms:

6.7 + x = -9.7  Solving 6.7 + x = -9.7 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.7' to each side of the equation.

6.7 + -6.7 + x = -9.7 + -6.7 Combine like terms: 6.7 + -6.7 = 0.0

0.0 + x = -9.7 + -6.7

x = -9.7 + -6.7 Combine like terms: -9.7 + -6.7 = -16.4

x = -16.4 Simplifying x = -16.4

The length is 13

Step-by-step explanation:

w+w+l+l= perimeter

if the length is 3m less than twice the width then let's do some math.

42 divided 2 =21. so the width and length of one side have to equal 21. For example, let's use 8 as the width. The length would be twice(16) minus three(13) 13 plus 8 is 21. WOW it equals half of it so no we know the length is 13 and the wdith is 8.
