9 = -3 + n + 2n what does n equal ?

Answers

Answer 1

Step-by-step explanation:

9=-3+n+2n

9+3=n+2n

12=3n

n=12/3

n=4

Answer 2

[tex]9 = - 3 + n + 2n[/tex]

now let's flip this equation to make things easier

[tex] - 3 + n + 2n = 9[/tex]

now move -3 to the other sidewhen we move -3 to the other side it turns into positive 3

[tex]n + 2n = 9 + 3[/tex]

now add the values on both sidesn + 2n will be equal to 3n and 9 + 3 will be equal to 12

[tex]3n = 12[/tex]

now move 3 to the other sidethe multiplication sign that binded 3 and n together will change into division when moved to the other side

[tex]n = \frac{12}{3} [/tex]

when we divide 12 and 3 we will get 4

[tex]n = 4[/tex]

so final answer is 4

hope that helps !

Find the measures of all four angles if m∠2 − m∠1=30°

Answers

Answer:

m∠1 = m∠3 = 75°

m∠2 = m∠4 = 105°

Step-by-step explanation:

From the figure attached,

m∠1 + m∠2 = 180° [Supplementary angles]------(1)

Since, m∠2 - m∠1 = 30°

m∠2 = 30° + m∠1 -----(2)

By substituting the value of ∠2 from equation (2) to equation (1),

m∠1 + (m∠1 + 30°) = 180°

2(m∠1) + 30° = 180°

2(m∠1) = 150°

m∠1 = 75°

Therefore, m∠2 = 180°- m∠1 = 180° - 75°

                  m∠2 = 105°

Since, ∠ 2 ≅ ∠4 [Vertical angles]

m∠2 = m∠4 = 105°

Similarly, ∠1 ≅ ∠3 [Vertical angles]

m∠1 = m∠3 = 75°

Answer:  13.244

Step-by-step explanation:

At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.

Answers

Answer:

x = 2y --------(1)

75x + 250y = 800 ---------(2)

Step-by-step explanation:

Let the number of chicken wings be x

And the number of sliders be y

x = 2y --------(1)

75x + 250y = 800 ---------(2)

The system of equation is x = 2y and 75x + 250y = 800.

Important information:At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. here we assume the number of chicken wings be x and number of sliders be y

Equation:

x = 2y --------(1)

75x + 250y = 800 ---------(2)

tan x = -0.25 for 0< x < 720​

Answers

Answer:

Below in bold.

Step-by-step explanation:

The smallest angle for which -0.25 is the tangent is in the  second quadrant and is 165.96 degrees. The other angle in the fourth quadrant is 345.96 degrees.

So for the range 0 to 720, x = 165.96, 345.96 and  360 + 165.96 = 525.96 and 345.96+360 = 705.96 degrees.

Kane is training for a marathone. He started by running 3 miles during every training session. Each week plans to increase the distance of his run by 1/4 mile

Answers

Complete question :

Kane is training for a marathon. He starts by running 3 miles during every training session each week plans to increase the distance of his runs by 1/4 mile. Let w be the number of weeks. Write and expression to show the diatance kane runs in a training session after w weeks

Answer:

(11 + w ) / 4

Step-by-step explanation:

Given the following :

Initial miles kane plans to cover per session = 3 miles

Increase in miles covered per session = 1/4 mile per week

Hence, distance covered after w weeks :

Using the sum of an arithmetic progression formula:

Tn = a + (n - 1) d

a = first term = Initial / starting distance = 3 miles

n = nth term = number of weeks = w

d = common difference = constant increase in distance per week = 1/4

Hence, after w weeks :

= 3 + (w - 1) × 1/4

= 3 + (w/4 - 1/4)

= 3 + (w - 1) / 4

Taking L. C. M

(12 + w - 1) / 4

(11 + w ) / 4

The expression that shows the distance Kane runs in a training session after w weeks will be; (11 + w ) / 4

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that the Initial miles kane plans to cover per session = 3 miles

The Increase in miles covered per session = 1/4 mile per week

Using the sum of an arithmetic progression formula to calculate the distance covered after w weeks

Tn = a + (n - 1) d

a = first term = 3 miles

n = nth term = number of weeks = w

d = common difference = the constant increase in distance per week = 1/4

Hence, after w weeks,

= 3 + (w - 1) × 1/4

= 3 + (w/4 - 1/4)

= 3 + (w - 1) / 4

= (12 + w - 1) / 4

= (11 + w ) / 4
