Answer:

n= 3 1/9

Step-by-step explanation:

3/8n= 5/6 + 1/3

3/8n = 7/6

n = 7/6  ÷ 8/3

n=28/9

n= 3 1/9

Answer:

I think it's 3 1/9

Step-by-step explanation:

3/8n-1/3=5/6

9/24n-8/24=20/24

+8/24. +8/24

9/24n=28/24

÷9/24. ÷9/24

n=28/24÷9/24

n=28/24×24/9

n=672/216

Halfway Between 0 and 121

Halfway Between

When you ask "What number is halfway between 0 and 121?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=121.

Halfway Between Line

To find the number halfway between 0 and 121, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 0 and 121 into our formula, we get:

(0 + 121)/2 = 60.5

Thus, the number halfway between 0 and 121 is 60.5

Answer:

solution given;

half way between 0 and 121=?

let a=0

and

b=121

we have

halfway =[a+b]/2=[0+121]/2=60.5

half way between 0 and 121 is 60.5

Answer:

a² + 2ab + b² + a² - 2ab + b²

2a² + 2b²

Step-by-step explanation:

Remember (a + b)² = a² + 2ab + b²

            and (a - b)² = a² - 2ab + b²

Answer:

The sequence is arithmetic

Step-by-step explanation:

Here we want to determine the sequence is arithmetic

If the sequence was arithmetic, the difference between the terms would be constant

We have this as;

10-(-12) = 22

32-10 = 22

54-32 = 22

As we can see, the difference is constant and so we have it that the sequence is arithmetic

Answer:

Measure of 3rd angle is 80 degrees

angle SAX - angle PAX = measure of 3rd angle (SAP)

Answer:

answer is 10

Step-by-step explanation:

2x^2(x-5) /10x

x=10

so,

=2*10^2 (10-5) / 10*10

=2*100(10-5) /100

=200*5 / 100

=1000/100

=10

The value of b when x = 10 is 10.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

b = 2x² (x - 5) ÷ 10x

When x = 10 find b.

Now,

b = (2x² (x - 5))/ 10x

Substitute x = 10

b = 2 x 10² ( 10 - 5) / 10 x 10

b = 200 x 5 / 100

b = 10

Thus,

The value of b when x = 10 is 10.

We conclude that, at 4 minutes, both will have the same height which is 200 feet.

Step-by-step explanation:

Given the system of equations

[tex]y=400+50x[/tex]

[tex]y=300+25x[/tex]

Important Tip:

Graphing the system of equations

The graph of the equation y = 400 + 50x

First, determine the y-intercept of the equation y = 400 + 50x by substituting x = 0

[tex]y = 400 + 50x[/tex]

[tex]y = 400 + 50(0)[/tex]

[tex]y = 400 + 0[/tex]

[tex]y = 400[/tex]

Thus, we determine that the ordered pair (0, 400) represents the y-intercept of the equation y = 400 + 50x.

Next, determine the x-intercept of the graph of the equation y = 400 + 50x by substituting y = 0

[tex]y = 400 + 50x[/tex]

[tex]0=400+50x[/tex]

switch sides

[tex]400+50x=0[/tex]

Subtract 400 from both sides

[tex]400+50x-400=0-400[/tex]

Simplify

[tex]50x=-400[/tex]

Divide both sides by 50

[tex]\frac{50x}{50}=\frac{-400}{50}[/tex]

Simplify

[tex]x=-8[/tex]

Thus, we determine that the ordered pair (-8, 0) represents the x-intercept of the equation y = 400 + 50x.

Important Tip:

The red graph on the diagram represents the equation y = 400 + 50x having the y-intercept (0, 400) and x-intercept (-8, 0)

Please check the attached diagram.

The graph of the equation y = 300 + 25x

Now, determine the y-intercept of the equation y = 300 + 25x by substituting x = 0

[tex]y = 300 + 25x[/tex]

[tex]y = 300 + 25(0)[/tex]

[tex]y = 300 + 0[/tex]

[tex]y = 300[/tex]

Thus, we determine that the ordered pair (0, 300) represents the y-intercept of the equation y = 300 + 25x.

Next, determine the x-intercept of the graph of the equation y = 300 + 25x by substituting y = 0

[tex]y=300+25x[/tex]

[tex]0 = 300 + 25x[/tex]

switch sides

[tex]300+25x=0[/tex]

Subtract 300 from both sides

[tex]300+25x-300=0-300[/tex]

Simplify

[tex]25x=-300[/tex]

Divide both sides by 25

[tex]\frac{25x}{25}=\frac{-300}{25}[/tex]

Simplify

[tex]x=-12[/tex]

Thus, we determine that the ordered pair (-12, 0) represents the x-intercept of the equation y = 300 + 25x.

The blue graph on the diagram represents the equation y = 300 + 25x having the y-intercept (0, 300) and x-intercept (-12, 0)

Please check the attached diagram.

Analyze the POINT OF INTERSECTION:

As we already know that the point of intersection of the two lines would give us the point at which both have the same height.

The diagram indicates that:

at x = -4, the value of y = 200.

It is the point where both lines meet.

Thus, the point of intersection of the two lines is:

(x, y) = (-4, 200)

Conclusion:

As x represents the time in minutes and y represents the height in feet.

Thus, we conclude that at x = 4 minutes, both will have the same height i.e. y = 200 feet

Therefore, we conclude that, at 4 minutes, both will have the same height which is 200 feet.

This is what it is equal to:

9×3x=27x

9×8=72

Therefore it will be:

[tex]27x + 72[/tex]

hope it helps!

Answer:

27x+72

Step-by-step explanation:

You have to use the distributive property to simplify the expression. Therefore, you have to  multiply both terms inside the parentheses.

1. 9*3x=27x

2. 9*8=72

They could not be added together, as they are not like-terms. So, you just write it down as 27x+72.
