4x+1=5+2(2x-4)
4x + 1 = 5 + 4x - 8 simplify
4x + 1 = 4x - 3 notice that this has no solution.......we can't add 1 to something and expect to get the same result by subtracting 3 from the same thing
Saladin, I answered this one here : http://web2.0calc.com/questions/which-of-the-ordered-pairs-in-the-form-x-y-is-the-solution-equation
I meant find the volume of the rectangular prism.
(-9, 3) = 6(-9) - -3/2 = -54 + 3/2 and this can't posssibly = 14
(2, - 4) = 6(2) - (-4/2) = 12 + 4/2 = 12 + 2 = 14
So (2, -4) is the solution that works......
(a + 5) = (1/5) (5a + 25) factor 5 out of the parentheses on the right
(a + 5) = (1/5) (5) (a + 5)
(a + 5) = 1(a + 5)
(a + 5) = (a + 5) this is an identity......it has infinite solutions
Let's solve for option A first.
x = -6
y = -14
(7 * -6) - (5 * -14) = 28
(-42) - (-70) = 28
(-42) + 70 = 28
70 - 42 = 28
A is true.
Now for B.
x = -1
y = -7
(7 * -1) - (5 * -7) = 28
(-7) - (-35) = 28
35 - 7 = 28
B is true.
Then C.
x = 4
y = 10
(7 * 4) - (5 * 10) = 28
28 - 50 = 28
-22 = 28
-22 ≠ 28
So C is false.
Last of all, D.
x = 7
y = 9
(7 * 7) - (5 * 9) = 28
49 - 45 = 28
4 = 28
4 ≠ 28
And D is false, too.
So the only solutions for (x,y) is A and B.
How many solutions does the equation have?
a+5=1_(5a+25)
5
A) one solution
B) infinite solutions
C) no solution
Red Die
Odd numbers: 1, 2, 3, 4, 5, 6
Probability: 3 / 6 = 1 / 2
Green Die
Perfect Squares: 1, 2, 3, 4, 5, 6
1 is a perfect square as √1 = 1
4 is a perfect square as √4 = 2
Probability: 2 / 6 = 1 / 3
1 / 2 * 1 / 3 = 1 / 6
99 / 333 = 33 / 111
= 11 / 37
Hint
You must do the multiplication and the division Before you do the subtraction!
Circumference of patio = dπ
= 15π feet
= 15 * 3.142 feet (taking π = 3.142)
= 47.13 feet
What do you mean by "concrete"? If we are asked if Al has enough budgeted for the patio, then we must find the height of the patio!!
I will now assume that the height of the patio is h feet.
47.13 * h = 47.13 h square feet
47.13 h square feet * $0.32 ≈ $15.08 h
If :
$15.08 h > $215, then Al doesn't have enough money budgeted.
If:
$15.08 h ≤ $215, then he has enough money budgeted.
one out of two times one out of three or one sixth
If the prism is a rectangular prism (a box), then the volume is found by multiplying the length times the width times the height.
V = 25 x 50 x 2 = 2500 cubic meters.
[ sin(26) x 5 ] / [ sin(121) ] = 2.557...
Factor 6s2 + 56s + 72 = 2(3s2 + 28s + 36)
This is as far as it can be factored using only whole numbers.
Ok, thanks Cphill, I would've long gone.

you have 95
thanks
OK.... 6 out of thirteen are fiction and 7 out of thirteen are non-fiction
How many sets of thirteen are there in 91 ?
91/13 = 7
7 out of thirteen are non fiction there are SEVEN sets if THIRTEEN 7 x SEVEN = 49 non-fiction books !
This angle falls into the frist quadrant since both the cosine and tangent are positive
And r = sqrt (7^2 + 24^2) = sqrt(625) = 25
And cos (theta) = x / r = 7/25
So....using an identity
sin(theta / 2) = sqrt ( [1 - cosx] 2 ) = sqrt ( [1 - 7/25]/2) = sqrt( [25 - 7] / 50) =
sqrt [ 18/50] = sqrt [ 9/25] = 3/5
Thanks, heureka.....I followed what you did....but....I have question..... in your fifth step....you state that :
Γ(0.5) = √ pi
How is this determined????
Also, does this imply that
Γ(0.5) = Γ( -0.5 + 1) = -0.5 * Γ(-0.5) ?????
Is it possible to apply the gamma function to a negative real number???.......
147 - x% = 89,6
How do I find X, please help
147 - x%(147) = 89.6
x% x 147=147 - 89.6
x% x 147=57.4
x=57.4 / 147=.390476
x=.390476 x 100 =39.0476%
