Question 240561: In one season, Kim ran 18 races. This was four fewer races than twice the number of races Kelly ran. How many races did Kelly run?
Answer by College Student(215) About Me  (Show Source):
You can put this solution on YOUR website!
Hello!
.
If Kelly ran x number of races, we can then say Kim ran 2x-4=18.
So we now solve for x to determine how many races Kelly ran.
.





.
Since Kelly is x, she ran 11 races.
.
Let's check for Kim's number of races.



... it checks!

evaluate (-6c)^2 and 6c^2 when c = 10
-----
(-6c)^2 = (-6*10)^2 = (-60)^2 = 3600
-------------------------------
6c^2 = 6*(10)^2 = 6*100 = 600

Question 241466:

Answer by jvurzua(1) About Me  (Show Source):
You can put this solution on YOUR website!
Solve using the substitution method. First, solve one equation for one variable.
s + t = - 4,
s - t = 2

first we need to get single a single variable on one side of the equation, which is simpler in the second one.
subtract s from both sides and we get -t = 2-s
the we have to reverse the signs t = -2 + s so we have a positive value of T to substitue into the first equation. now we replace T in the first equation with -2+s
S + (-2 + S) = -4
-2 + 2s = -4
now we add 2 to each side to eliminate it single out the variable on the left side of the equation. (-2+2) + 2s = (-4+2)
2s = -2
now divide both sides by 2 to single out the variable on the left side of the equation. 2s/2 = -2/2
s = -1 Now that we haw a value for s we can check our work by substituting it into the original equations to see if it is true.
-1 + t = -4
t = -3
-1 + -3 = -4 True
S - T = 2
-1 - -3 = 2
-1 + 3 = 2 True
Hope this helps.

Solve using the substitution method. First, solve one equation for one variable.
s + t = - 4,
s - t = 2
--------------------
solve the 2nd for "s":
s = t+2
-------------------
Substitute into to 1st and solve for "t":
t+2 + t = -4
2t + 2 = -4
2t = -6
t = -3
------
Since s = t+2, s = -3+2 = -1
================================================
Solution:
t = -3
s = -1

Hello,
Yes, it's possible. Let's take the first two terms
x^3 + 3x^2 which we can rewrite as:
x^2(x+3)
Now look at the next two terms:
8x + 24 Which we can rewrite as:
8(x+3) Here's the trick. Notice in the parenthesis we have x+3 so this can be rewritten as:
(x^2+8)(x+3)
To check this out multiply these two out and should come out the the original. x^3 + 3x^2 + 8x + 24

The first step in factoring is to try to take out any common factors. In this case, you have a common factor of a, so take out the "a" factor.

a(a^3 -b^3)

Answer by Theo(675) About Me  (Show Source):
You can put this solution on YOUR website!
your equation is:

1/(x-4) + 4/(4x-4) = 5/4

factor out the 4 in 4/(4x-4) to get:

1/(x-4) + 1/(x-1) = 5/4

your common denominator is going to be (x-4)*(x-1)

multiply 1/(x-4) * (x-1)/(x-1) to get (x-1)/((x-4)*(x-1))

multiply 1/(x-1) * (x-4)/(x-4) to get (x-4)/(x-4)*(x-1)))

your equation becomes:

(x-1)/((x-4)*(x-1)) + (x-4)/((x-4)*x-1)) = 5/4

combine the two fractions with the common denominator to get:

((x-1) + (x-4)) / ((x-4)*(x-1)) = 5/4

simplify by combining like terms to get:

(2x-5)/ ((x-4)*(x-1)) = 5/4

multiply both sides of this equation by 4 to get:

(4 * (2x-5))/ ((x-4)*(x-1)) = 5

simplify by removing parentheses in the numerator on the left hand side of the equation to get:

(8x-20) / ((x-4)*(x-1)) = 5

multiply both sides of this equation by ((x-4)*(x-1)) to get:

8x-20 = 5 * ((x-4)*(x-1))

simplify by performing indicated operations and removing parentheses to get:

8x-20 = 5x^2 - 25x + 20

subtract 8x from both sides of the equation and add 20 to both sides of the equation to get:

0 = 5x^2 - 33x + 40 which is the same as:

5x^2 - 33x + 40 = 0

use the quadratic equation to solve this equation to get:

x = 5
or
x = 1.6

substitute for x in the original equation to confirm the result.

I did that and the results are confirmed so these values are your answer.

The quadratic formula is:



the standard form of the quadratic equation is:

ax^2 + bx + c = 0

your equation is:

5x^2 - 33x + 40 = 0

a = 5
b = -33
c = 40

plug those values into the quadratic formula and you get:

which becomes:

which becomes:



The result is x = 5 or x = 1.6

Answer by rapaljer(3622) About Me  (Show Source):
You can put this solution on YOUR website!
2(3x-1)-5(2x+3)=4x-7
6x-2-10x-15=4x-7

Next, combine like terms on the left side:
-4x-17=4x-7

Now, you need to get all the variable terms on one side and the number terms on the other side. It doesn't matter which side you get the variables on, but let's say you want ot get all the variables on the LEFT side. You need to get rid of the 4x on the right side, by subtracting 4x from each side:
-4x-4x-17=4x-4x-7
-8x-17=-7

Now, since you have all the variables on the LEFT side, you need to get all the NUMBER terms on the right side. To get rid of the -17, add a +17 to each side:
-8x-17+17=-7+17
-8x=10

Now, to "undo" the multiplication of x by -8, you must DIVIDE both sides by -8:

Question 240544: Please help me solve using the substitution method
7x+3y=-25
-7x+y=29

Answer by unlockmath(121) About Me  (Show Source):
You can put this solution on YOUR website!
Hello,
Let's take the second equation and get y alone. To do that we add 7x to both sides. That will give us:
y=7x+29 Now we can put this into the first equation:
7x+3(7x+29)=-25 Distribute and combine like terms we get:
28x + 87=-25 Now subtract 87 from both sides gives us:
28x = -112 Divide both sides by 28 gives us:
x = -4 To find y just plug -4 into either equation and we get:
y=1 To see if these are right plug both values into both equations and it should come out the same.

Question 240535: Please help me solve by the elimination method
x+3y=16
-x+8y=17

Answer by solver91311(5072) About Me  (Show Source):
You can put this solution on YOUR website!


The strategy for solving by elimination is to find a multiplier for one or both of the equations such that you make the coefficient on one of the variables in one of the equations be the additive inverse of the coefficient on that same variable in the other equation.

In the case of given example, you don't have to find a multiplier for either equation because you already have a coefficient of 1 on x in the first equation and a coefficient of -1 on x in the second equation.

Just add the two equations, term-by-term. Since you will be adding x to -x, you will end up with 0x, effectively eliminating (hence the name of the method) that variable. The end result will be a single equation in one variable, in this case, y. Solve for the remaining variable, and then use this value to substitute back into either of the original equations in order to solve for the variable that you eliminated.

___ 8t = u ___ (there is only one pair of digits that works here)

"If the digits were reversed, the resulting number would be 9 less than 5 times the original number"
___ 10u + t = 5(10t + u) - 9
___ 10u + t = 50t + 5u - 9
___ 5u + 9 = 49t

substitute the value of u from the 1st part to find the value of t
___ then substitute t back to the 1st part to find the value of u


Question 238567: Solve by the elimination method.
4x-9y=6.5
7y-2x=-4.5

Answer by Alan3354(6094) About Me  (Show Source):
You can put this solution on YOUR website!
4x-9y=6.5
7y-2x=-4.5 times 2 --> -4x+14y = 9
-------------
+4x -9y = 6.5
-4x+14y = 9
-------------- Add
5y = 15.5
y = 3.1
---------
4x - 9y = 6.5
4x - 9*3.1 = 6.5
4x = 34.4
x = 8.6

A= 1/2h (b1+b2 for b1
------------
A right bracket is missing, I think it goes here:
A= 1/2h (b1+b2)
2A = h*(b1 + b2)
2A/h = b1 + b2
b1 = (2A/h) - b2

5(2x+3)=4(x-1)+1

Answer by rfer(2688) About Me  (Show Source):
You can put this solution on YOUR website!
5(2x+3)=4(x-1)+1
10x+15=4x-4+1
subtract 15
10x+15-15=4x-4+1-15
10x=4x-18
subtract 4x
10x-4x=4x-4x-18
6x=-18
divide by 6
6x/6=-18/6
x=-3
