50q-43 = 52q - 81 Subtract 50q from both sides
-43 = 2q - 81 add 81 to both sides
38 = 2q divide by 2
19 = q
I assume your asking what 14+2 is, and it equals 16.
Great !! SMOKE came from my keyboard when I pressed it!!!! WHAT do I do now....I DO NOT want to dump my beer on it!!!!
3sqrt(8/2) Should equal 1.58740105151968 OR 1.59
Below is a link to a detailed explanation.
-- Two Step Equations and Inequalities --
$ 85 original price a ) 20 percent off is 80% of original price 85 (.8) = $ 68
b) 85 less 15 % is 85% of original price 85 (.85) = 72.25
then take another 10% off ...pay 90% of this new price
72.25 x .9 = $ 65.03 final price
Plz explain
DO NOT press that button......nobody here knows WHAT might happen.....!!!!!!!
The calculator option on this specific calculator doesn't seem to work, so, probably not.
20 of 45 have oak floors of these 20 percent have granite counters 20/45 x .2 x 100% = 8.88%
Oh! I know this one.. uhh.. ...two! Yeah... ...yeah! It equals two!
COT is cotangent cotangent is 1/ tangent
92 = 2 x 2 x 23 are the prime factors of 92
according to the web2.0 calculator:
270/6 = 45
(126)^(1/3) ≈ 5.013 cm
It depends on the element you are talking about, you'll have to look at the atomic weight of the element and divide THAT into the number of grams that you are dealing with to get the number of moles..... Further questions...
?
24/60 x 100% = 40
≈ - .545454.......
-11
No, Melody.....you are incorrect.....there is no reason.....LOL!!!!!!
[ 9^(−1/2) * 3^3 + 27^(1/3) ] / [ (1/3)^(−3) + (1/9)^(1/2) ] =
[ 1/3 * 3^3 + 3] / [ 27 + 1/3] =
[ 9 + 3 ] / [ 82 / 3 ] =
[12* 3] / 82 =
36 / 82 =
18/41
-x^2 = -4x + 2
0 = x^2 -4x + 2
x = 2 - sqrt(2) or x = 2 + sqrt(2)
There is a reason :)
Think about this
\(4^2\div 4^2 = 4^{2-2}=4^0 \qquad \text {I have used the index laws}\)
but
\(4^2 \div 4^2 = 16\div 16 = 1\)
therefore
\(4^0=1\)
