You will need to choose one of the equations, and solve for one of the variables. Then, plug the new information into the equation for the variable. Here is an example:
3x - 6y = 12
x + 3y = 3
I choose to work with the second equation, then solve for 'x', which...

(x^3y^2) + (x^2y^2) + (x^2y)
You can rewrite the expression to look like this:
(x*x*x * y*y) + (x*x *
y*y) + (x*x * y)
You then ask, "What is the greatest number of x's that I can pull from each term?"
Each term has at least one x. If you look closer,...

Female gods were a symbol of fertility. Examples: Isis (Egyptian), Osiris (Egyptian), Aphrodite (Greek), Hera (Greek) and Ishtar (Mesopotamian)

A) To find out how much moisture is in the sand in terms of the dry sand, we need to take the difference in weight, and find out what the percentage is compared to the dry sand, like this:
32 (wet sand) - 30.8 (dry sand) = 1.2 (moisture)
(moisture)/(dry sand)=(percentage of moisture...

Summer time can be a bit of a struggle for tutors. Public schools are closed, and students as well as tutors are ready for a break. For most tutors, generating new leads and keeping busy in the Summer is a challenge. If you are new to the game, your first Summer is the toughest. Here is an idea that may just keep you moving along.
Your local community college offers Summer classes. Students...

Are you supposed to use substitution, elimination or graphing?

x= .25
y= .50
Change back from $20 = 10.75
-----------
x + y = 30
.25x + .50y = 10.75
-----------
Substitution? Elimination? Graphing?
----------
Substitution:
x + y = 30
.25x + .5y = 10.75
Pick one of the equations, and...

Set up the equation as y=2x-7
Solve for 'x'
Switch 'x' and 'y'. This is your inverse.

As long as you don't have any coefficient for your 'a' term, then here is what you do:
Factor your 'c' term. Don't worry about positive or negative yet:
28 * 1
14 * 2
7 * 4
We need to decide which pair to use. Now we check the sign on the 'b'...

No. A hot spot is like Hawaii, where there is one location where volcanic activity occurs for some length of time. Then, the plate the volcano is on moves, or shifts. the mountain moves, and a new one is built over the hot spot. This is different from subduction zones, where one plate moves under...

When working with quadratics, the usual formula for working with them is as a trinomial where ax2+bx+c=0. The 'a' 'b' and 'c' are simply coefficients that may or may not be in the formula.
If there is no number in front of one or the other of the variables, then the coefficient is assumed...

First thing to know - remember that any number over itself as a fraction equals "1"
Now you have to create an improper fraction from the mixed number 4 1/2. Let me know if you have difficulties with this.
What happens if you multiply this new improper fraction by "1"...

d=rt
Distance = Rate * Time
Distance = (15) * (3)

a) Slope-intercept form is y=mx+b. You must solve for 'y', and make the 'x' term the first one on the right side of the equation when you are finished.
b) The slope is the 'm' in the equation. it is the number (called the coefficient) that is with the 'x'
c) The...

5x = 6x^2 - 3
First you need to put the equation into ax^2 +
bx + c = 0. For this problem, all we have to do is subtract 5x from both sides:
0 = 6x^2
- 5x - 3
'a' is 6, 'b' is -5, and 'c' is -3
Now you plug them into the quadratic formula and carefully...

I would use the four main atom models as my evolution explanation. Start with J.J. Thompson's model, then talk about how Rutherford refined that model, then talk about Bohr's model, emphasizing the shells and orbits, and finish with the currently accepted model of the electron cloud.
Hopefully...

A - While the "radical southern states" are mentioned, it is only a part of the passage and not the main point.
B- Nothing in the passage indicates that the North expected or demanded the war. The passage puts demand more on the southern states.
C- The passage...

I agree with Jordan. C is the only answer that best describes how the war was inevitable, or unavoidable.
A, B and D all describe legalities surrounding our nation at the time, and do nothing to actually describe WHY the war (this great crisis) was unavoidable (because of the smaller,...

Ebenezer didn't really show you how to round. He just answered the question for you, which doesn't usually help much. Maybe I can help.
60330.02636
In order to know whether to round the second decimal place up or down, we need to look at the
third decimal place. If...

*backs away from the problem*
I apologize for getting in the way.
