It's 15\n\n3 + 3 + 3 x 3 \n(3 + 3) + (3 x 3)\n(6) + (9) = 15

3p > 21 + 6\n now adD 21+6 on the right hand side\nthis will give u 27\n3p > 27\nnow this will give u 27 divided by (/) 3\np > 27/3\np> 9\nthe answer is : p>9

get the x's on one side and the numbers on the other.\n\nto do that -- perform the opposite operation to each part you want to move on BOTH sides of the equation ..\n\n3x + 3 = 15 - x\n3x (+ x) +3 = 15 - x (+ x)  ---- adding x to both sides\n4x + 3 = 15\n4x + 3 (- 3) = 15 (- 3) ---- subtract 3 from both sides\n4x = 12\n\nI'll bet you can do the last operation in your head ... just divide by 4 and you have your answer to x!

27=3x3x3\n189=3x3x3x7\nto calculate lcm, just cancel out (one each of the pair of) the numbers that appear twice; you're left with 3x3x3x7, or 189.\nApparently your other respondent thinks if he can't do it it can't be done...

When you go through this, make sure I have put the parentheses in the correct place in the question.\n\n#1.\n\n3^x * 9^-x = 27^x \n3^x * 3^-2x = 3^3x\n3^-x = 3^3x\n-x = 3x (by taking log base 3)\nx = 0\n\n#2.\n\n1/(e^-x^2) = (e^3x)(1/e^2) \ne^2 = (e^-x^2)(e^3x)\ne^2 = e^(-x^2+3x)\n-x^2+3x=2 (by taking ln)\nx^2-3x+2=0\n(x-1)(x-2)=0\nx = 1 or x = 2\n\n#3.  (Notice that atheerai go this one wrong.  Make sure you check your answers by plugging them back into the original equation.)\n\n2^2x + 2^(x+2) -12=0\n(2^x)^2 + (2^2)(2^x) - 12 = 0\nor, alternatively\ny^2 + 4y - 12 = 0 where y = 2^x\n(y + 6)(y - 2) = 0\ny = 2^x = -6 is not possible\nbut y = 2^x = 2 gives x = 1\n\n#4.\n\n2^(x+1) = 5^(1-2x) \n(x+1)ln2 = (1-2x)ln5\nxln2 + ln2 = ln5 - 2xln5\nx(ln2 + 2ln5) = ln5 - ln2\nx = (ln5 - ln2)/(ln2 + 2 ln5)\n\n#5.\n\nln(x-3) - lnx = 3\nln((x-3)/x) = 3\n(x-3)/x = exp(3)  (taking e to the power of both sides)\n x - 3 = x*exp(3)\nx(1-exp(3)) = 3\nx = 3/(1-exp(3))

The product of two numbers is another way of saying the two numbers multiplied together.\n\nSo the product of 3 and 69 is 3x69 = 207.

The equation to start with is : x^3 = 27\nor, x^3 = 3^3\nor, x^3 - 3^3 = 0\n\nThis is a difference of two cubes,\nso it can be factored :\n\n(x - 3)(x^2 + 3x + 9) = 0\n\nOne solution is seen to be x = 3.\n\nThe other solutions are obtained by\napplying the quadratic formula to :\n\nx^2 + 3x + 9 = 0\n\nThis gives :\n\nx = {-3 ± sqrt[3^2 - 4(1)(9)]} / (2 * 1)\n\n= [-3 ± sqrt(-27)] / 2\n\n= [-3 ± i*3*sqrt(3)] / 2\n\n= (-3 / 2) ± [3*sqrt(3) / 2] * i

We'll call the number x.  Let's translate this into equation form so we can solve it algebraically.\nThree times: 3x\nIncreased by 4: +4\nSum is 37: =37\n\nWhat do we have?\n\n3x+4=37\n\nWe can now solve.  It helps to put things into math so the process of finding the answer is really easy to do.\n\n\n3x + 4 = 37\n3x = 33\nx = 11\n\n\nThe number is 11.  Let's check:\n\n3(11) + 4 = 33 + 4=37!\n\nIt's good!\n\nHope this helps.

actually, i think it's 15 because however much you add or subtract in the first two, it always adds up to 6.\nAND\nyou always add once and subtract once\nTHUS\nyou have to subtract 3 from 18

bring the a's to one side... u then get 9a = 27 ... divide and answer is a = 3

you don't even need a calculator.  You should be able to work that out on paper.  9 x 7 is what?  Remember the magic quality of 9, the answer is one less than the number you are multiplying by, and adds to nine, so one less than 7 is 6, plus three is nine, so 9 x 6 is 63.  Write down the 3, carry the 6.  3 times 7 is?  Of course, 21, plus the 6 you carried 27.  write 27 next to the 3 you already have, and it's...\n273
