Solve the equation, 2x^2 - 11x - 6 = 0.

Solve the equation, x2 - 2x - 8 = 0 by completing the square .
x = 4 or x = -2

x = 4 or x = 2

x = -4 or x = -2

x = -4 or x = 2

Gouda = X
Edam = Y

3x + 2y = 24.40
4x + 5y = 47.70

You try to solve for 1 variable by getting rid of the other. So you get 1 equation to have a negative coefficient, and the other to have the positive of that coefficient. ( e.g. 7x and -7x )

First off, multiply the equation 3x + 2y = 24.40 by the negative of the second equations first term's coefficient ( the negative of 4x + 5y = 47.70's first term's ( 4x ) coefficient is "-4". ).
This is the above step in an equation.

-4(3x + 2y = 24.40) =
-12x - 8y = -97.6 ( <---- remember this )

Then, you multiply the second equation by the positive of the first equation's first term's coefficient ( the first term's coefficient of the equation 3x + 2y = 24.40 is "3" )
This is the above step in an equation.

3( 4x + 5y = 47.70 )
12x + 15y = 143.10 ( <---- remember this, too )

Bring the two things i told you to remember next to one another.

-12x -8y = -97.6
12x + 15y = 143.10

See? The "x" values (-12x and 12x) cancel out each other when you add the two equations. Then you proceed to add these.

2nd terms (add) -8y + 15y = 7y
The answers (add) -97.6 + 143.10 = 45.5

So in the end the "x" values cancel out and you get this

7y = 45.5
Divide by 7 and you get
y = 6.50

Plug in the "y" ( 6.50 ) value into one of the original equations to find the value of "x".
Let's use the first.

3x + 2y = 24.40
Now "y" = 6.50. Plug it in!

3x + 2(6.50) = 24.40
3x + 13 = 24.40
Subtract 13 from both sides and you get
3x = 11.40
Divide by 3
x = 3.8

Gouda = x Gouda = 6.50
Edam = y Edam = 3.80

Simple ( not really ) as that!

Plug in the answers to the other equations to check.]

Algebra homework help? ASAP please! 10 points FOR SURE!?

1. Let length be l and let width be w.

Length is twice the width

P = 2l + 2w = 2(2w) + 2w = 6w

P = 6w
36 = 6w
w = 36/6 = 6

The width is 6cm and the length is 6*2 = 12cm.

A = l*w = 6*12 = 72cm

2. Let Alice be a. Let Barbara be b. Let Kamran be c.

a = 2b
c = b - 2

a + b + c = 46
2b + b + b - 2 = 46
4b = 46 + 2
4b = 48
b = 48/4 = 12

Barbara is 12 years old. Alice is 12*2=24 years old and Kamran is 12-2=10 years old.

3. Let x be the no. of hits.

x/100 = 0.25
x = 0.25*100 = 25 hits

Jerry needs to do 25 consecutive hits to get a batting average of 0.250. (he needs to do 5 more hits)

Please answer this as soon as possible. Algebra isn't my best subject and I'd like a little help, Thank you.
#1, Show an equation and a solution for the problem. How much water must be added to 12 L (liters) of a 40% solution of alcohol to obtain a 30% solution?

#2Show an equation and a solution. How much pure antifreeze must be added to 12 L of a 40% solution to obtain a 60% solution. (Remember that pure antifreeze is 100% = 1.)

#3 Show an equation and a solution for the problem. Arnold needs a 25% solution of nitric acid. He has 20 milliliters (ml) of a 30% solution. How many ml of a 15% solution should he add to obtain the required 25% solution?

Pre Algebra Homework help. Quick!?

Solution: take the sum of the squares of the two smallest numbers and see if it is equal to the square of the third:
2.1, 2.8, 3.5
2.1 * 2.1 = 4.41
2.8 * 2.8 = 7.84
together: 12.25
3.5 * 3.5 = 12.25 So it is a Pythagorean Triple.

So now you must be able to check the other 3 with your calculator.
