The problem with this site is the fact that students do not reply when answers are given. I like algebra.com because students take time to thank the online math tutors for help. I have not yet seen...

We use D = rt, where D = distance, r = rate or speed and t = time (in hours).

Just divide the top by the bottom.
You were given 11/5. See attachment for answer.

You need to rewrite this fractional equation. It makes no sense as posted. There should not be two equal signs.

There is no reason to be scared. Middle school is just another journey in your life. You will face many new roads in life. When you get to high school, you will feel likewise but it's just a change...

Why don't you ask a school counselor? Go to your local education department or school district and find out.

It could be your study skills. Tell me more about your study skills? Do you take good notes during class time? Do you study one section and not go to the next section without being totally ready? ...

You need to speak to your school academic counselor or guidance counselor, your parents and your teacher.

Things to do:

1-study everyday... no exceptions!

2-Hire a tutor (if you get stuck).

3-Ask questions during class time.

4-Join study groups during after school time.

What is your math question?

You did not provide a question.

Set up a proportion:

let t = time.

5 miles/1 mile = 1 hour/t

Solve for t.

5 miles times t = 1 mile times 1 hour or this way:

Go to the link provided to learn about venn diagram math:

Logic - Venn diagrams

To solve by ellimination means to do away with either the x or y variable.

We have this:

2x - y = 5.....EQUATION A
8x - 4y = 20.....EQUATION B

There is no number I can use to do away with x...

This list of points, being a relationship between certain x's and certain y's, is a relation. The domain is all the x-values, and the range is all the y-values. You list the values without...

Average speed = total distance divided by total time.

Let r = average speed

Let D = total distance

Let t = total time

Here's your formula:

You can use the distance formula D = rt, where D = distance, r = rate or speed and t = time in miles per hour.

You will need to convert minutes to hours BEFORE using the distance formula.

If you do not show us your work, how is anyone going to know if effort was made at solving this question? It's easy to post questions without effort but none of us will be in your classroom to help...

Where's the figure? Your question states "figure given" but you forgot to upload the picture of the figure.

If you know the lengths of the sides and want to find the angle measures of a given triangle, use the law cosines.

Here is link:

The law of cosines. Topics in trigonometry

I hope this helps.

We have a sinusoidal function whose general form is

y = Acos(wt + p) + v

The following formulas will be useful:


Amplitude = | a |

Period = 2pi / w

tanx = sinx/cosx

cotx = cosx/sinx

On the left side:

(cosx)(tanx+sinxcotx)= cosx(sinx/cosx + sinx(cosx/sinx)

cosx(sinx/cosx) = sinx... cosx cancels out.

RULE:

a^(-b) = 1/a^(b)

We can use this rule to solve your negative fractional exponent question.

4/9 raised to the negative fraction -1/2 becomes 1/(4/9)^(1/2)... Notice that the fraction...

We have x^2 = 25

To solve this question, we take the square root of both sides of the equation.

When we take the square root, there are two possible answers:

To find the x intercepts of an equation, let y = 0 and to find the y-intercepts, let x = 0.

What is an intercept anyway?

An intercept is a point in the form (x, y) on either the x- or y-axis...

Question:

Isolate s for the linear equation -2 = 4r + s

To get a letter alone means to isolate the letter. So, to do this, simply subtract -4r from both sides of the equation.
