Answer:

3. 2x+18=4x+26

Step-by-step explanation:

2(x+9)=4(x+7)+2

2x+18=4x+28+2

2x+18=4x+<u>3</u><u>0</u>

riadik2000 [5.3K]

Answer:

Not 100 percent sure but i think the correct answer is the last one.

Step-by-step explanation:

I know that the answer is either the last one or before the last because they are dependent on each other. This is because the probability of both increases when they are added together. The more you have the more likely to get one of them. I went for the last one because i think that the value of together is greater than when they are added.

Again, not 100 percent sure, tried to give it my best shot.

Hope this helps.

Each byte contains 8 bits of information. Write an equation to represent the relationship between the number of packets and the
shepuryov [24]

Answer:8p

Step-by-step explanation:

Because their is 8 bits so x equals 8p I got p because the other equation on the problem was b = 1500p so we still using the same variable so p is the variable so 8p is the answer

Use the properties of 30-60-90 and 45-45-90 triangles to solve for x in each of the problems below. Then decode the secret messa
Flauer [41]

With the help of trigonometric function, the above problems have been calculated. See explanation below.

<h3>What are Trigonometric functions?</h3>

The term "trigonometric function" refers to functions that are periodic in nature and that shed light on how a right-angled triangle's angles and sides relate to one another.

The solutions to x in the respective problems is given as follows:

1) x = 5 /Sin(30°)

x = 10

!) Sin(45°) = 4/x

x = 4/sin(45°)

x = 4√2

I) Cos(45°) = √3 / x

x = √3 / Cos(45°)

x = √6

E) Tan(60°)

= (3√3) / x

x = (3√3) / 3

W) In trigonometry, every right-triangle that is isosceles in nature, the angle made by the legs and the hypotenuse will always equal 45°.

x = 45°

N) x² + x² = (7√2)²

x = 7

V) Tan(60°) = 7 / x

x = 7√3/3

K) x² + x² = (9)²

x = 9/√2

Y) Sin(60°) = 7√3/x

x = 14

M) Sin(30°) = x/11

x = 11/2

T) Sin(45°) = x/√10

x = √5

A) x + 2x + 90° = 180°

x = 30°

O) Sin(45°) = √2 / x

x = 2

R) Tan(30°) = x / 4

x = 4/√3

= 4√3 / 3

S) Sin(60°) = x / (10/3)

x = (5√3) / 3

What is the solution to this equation? 5x - 4 + 3x = 36   A. x = 5   B. x = 16   C. x = 20   D. x = 4
shepuryov [24]

Let's do this in steps, show your work!   | <em>Make sure to ask questions!</em>

#1. Simplify 5x - 4 + 3 to 8x - 4.

<u>8x - 4 = 36.</u>

#2. Add 4 to both sides.

<u>8x = 36 + 4. </u>

#3. Simplify 36 + 4 to 40.

<u>8x = 40.</u>

#4. Divide both sides by 8.

<u>x = 40/8.</u>  <------ <em>It turned into a fraction because it's easier to not divide a decimal. </em>

#5. Simplify 40/8 to 5.  

<u>x = 5. </u>

<h3>Therefore, x = 5.</h3>
