Answer:
n = 8
Step-by-step explanation:
10=6+n/2
Switch sides
6 + n/2 = 10
Subtract 6 from both sides
6 + n/2 -6 = 10-6
Simplify
n/2 = 4
Multiply both sides by 2
2n/2 = 4 times 2
n = 8

A model is made of an airplane. The plane is 150 feet long and the model is 20 inches long. What is the ratio of the length of the plane to the length of the model? Be sure to reduce your answer!
Answer:
7.5 : 1
Step-by-step explanation:
Given that :
Length of airplane = 150 inches
Length of model = 20 inches
Ratio of length of plane to that of model
Length of plane : length of model
150 : 20
15 : 2
7.5 : 1

Answer:
4 is true
Step-by-step explanation:
1) 5 is more than 2, but 4 is greater than 1, so it wouldn't be true.
2) 5 is less than or equal to 5, but -6 can't be more than or equal to -5.
3) Negative numbers are not greater than positive numbers.
4) -2 is greater than -4, and 3 is greater than 0.
Describe how you would tell that two lines are parallel or coincide by looking at the equations of the lines in standard form.
You can tell if two lines are parallel when they have the same slope but different y-intercept. For example, y = 2x - 4 and y = 2x + 4 would be parallel lines. If they coincide, then the two lines would be on top of each other. For example, first-line with the equation of 3x +3y = 9 and second-line having 9x + 9y = 27 are coinciding lines.

It costs $95 for 20 students to visit an aquarium. How much does it cost for 162 students?
It costs $
Answer:
$769.50
Step-by-step explanation:
It would cost $769.50 for 162 students because if you take 20 divided by 20 to get one student then you have to divide the money by 20 so you would get $4.75 per student. Then you have to take 4.75 times 162 because that is how many students they would pay for. So your answer would be $769.50 for 162 students to go to the aquarium

Answer:
[tex] - \frac{1}{3} [/tex]
Step-by-step explanation:
The only thing important in this question in the original equation is the slope, which is 3, the multiplyer for x. To find the opposite slope follow the steps below.
The first step is to make the original slope into a fraction.
[tex] \frac{3}{1} [/tex]
Then flip the numerator and denominator.
[tex] \frac{1}{3} [/tex]
Now multiply this value by -1.
[tex] \frac{1}{3} \times ( - 1) = - \frac{1}{3} [/tex]
There is the opposite slope of 3.

Step-by-step explanation:
well, 5.78 ÷ 3.9 = 1.4820 so 0.4 can go into 1.4820 3.705 times. hope this helps :) have a good day :D
Answer:
Ok so I got you
Step-by-step explanation:
1. 0.4x + 3.9 = 5.78
2. 0.4x = 5.78 - 3.9 = 1.88
3. 0.4x = 1.88
4. 0.4/ 1.88 = 4.7
5. x = 4.7
8. Number of boys in a class is twice the number of girls. 20% of the girls are brunettes and of the rest – half are blondes: Mary, Clara, Gina and Trisha. How many boys study in this class?
Answer:
20 boys
Step-by-step explanation:
b = 2g
100% - 20% = 80%
80% ÷ 2 = 40% = 0.4
0.4g = 4 ⇒ g = 4 ÷ 0.4 = 10
b = 2 × 10 = 20
There are 10girls and 20 boys study in the class.
Use intercepts to graph the linear equation
-5/2x+y=10
Answer:
y=5/2x+10 is the answer
9514 1404 393
Answer:
see attached
Step-by-step explanation:
The x-intercept can be found by setting y=0 and solving for x.
-5/2x = 10
x = 10(-2/5) = -4
The y-intercept can be found by setting x=0 and solving for y.
y = 10
Then the graph is made by plotting these points and drawing a line through them.

Winne is currently considering two plans for paying for piano lessons.
Answer:
Plan B
Step-by-step explanation:'
First u have to divide each one to see how much each piano lesson costs.
Plan A- 31.50/6=5.25
Plan B- 20.60/4=5.15
So since Plan B is less then Plan B would be the answer.

a line with a slope of -1/9 passes through point (9,-1). What is its equation in slope intercept form
Answer:
[tex] \huge \orange{y = - \frac{1}{9} x} \\ [/tex]
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
From the question we have
[tex]y + 1 = - \frac{1}{9} (x - 9) \\ y + 1 = - \frac{1}{9} x + 1 \\ y = - \frac{1}{9} x + 1 - 1[/tex]
We have the final answer as
[tex]y = - \frac{1}{9} x \\ [/tex]

Seth's local movie theater is running a promotion on tickets. If he purchases a movie pass for $40, he will pay $2 per ticket. Without the movie pass, the tickets cost $3.50. If Seth sees 50 movies per year, which will be the better by and why? Explain your answer using mathematical reasoning.
Answer:
I think the better buy is the movie pass one
Step-by-step explanation:
Look, he can see a movie whenever he wants without any hassle for $2. So $3.50 is more expensive per ticket.
Answer:
The better option would be buying the movie pass for 40 dolllars and Payne $2 a ticket for every movie.

if sees 50 movie a year then it would be
40+100=140
If without movie place

If ∠A and ∠B are complementary, find the value of x given that ∠A=3x-2 and ∠B=x+12
Answer:
x=20 degrees
Step-by-step explanation:
complementary means the angles equal 90 degrees
so ∠A+∠B=90 degrees
∠A=3x-2 and ∠B=x+12
so subsitute
(3x-2)+(x+12)=90
then solve for x
4x+10=90
4x=80
x=20 degrees is your answer
