This sounds more like arithmetic than math, except that the last 2 questions also involve units of measurement. Without doing the arithmetic, I'll tell you that the answer to #2 will be density in g/ml. (Yes, answerer 3, you can divide g by ml; what you can't do is add/subtract dissimilar units!) The answer to #3 will be volume in cm^3.

Actually I had something to help you but x=0 which makes it pretty difficult.\n\nI guess you could try to talk about tomatoes or something.  Say Tom (X) has 1/2 the amount of tomatoes that Jill has, plus four.  Or in other words, if you take Jill's amount of tomatoes, multiply it by two, and take Tom's amount and multiply it by three, there total amount of tomatoes will equal 12.  How many tomatoes does Jill have?  How many does Tom have?

hey try to think logically about the problem.. its really easy just too much words and it confuses you. so take a deep breath and then begin. take 25 % off of $375 and it will give you the answer..... im pretty sure about this but you cant trust me on those dog gone word problems, lol \ngood luck

1) 3 * sqrt(-8)\n= 3 * sqrt(4) * sqrt(-2)\n= 6 * sqrt(2) * i\n\n2) sqrt(1/6)\n= sqrt(6/36)\n= sqrt(6) / sqrt(36)\n= sqrt(6) / 6

So lets start with the first one. Make a division problem with 9.0 on the outside and 0.9 on the inside. 9.0 does not go into 0 but does go into nine. Raise the decimal and the answer is ten. It's a bit difficult to explain but here's your answers and when you go in next time ask your teacher for help::\n1. 10 \n2. 8\n3. 4.7\n4. 3.2\nOkay theres a few for you and you should be able to figure out the rest. For the next part you take what x is equal to and divide it by 1.2. So for\n13. 40.8/1.2=34\nAnd do the same for the rest!!\nGood luck!

1.) 3 &#92;/ x+2 - 4 = 3\nif you mean\n3 sqrt( x+2) -4 =3,\nthen\n3 sqrt(x+2) =7\nsqrt(x+2) = 7/3\nx+2 = 49/9\nx=49/9 -2\n\n2.) &#92;/ x+3 - &#92;/2x-8 = 1\nsqrt(x+3) -sqrt(2x-8) =1\nsqrt(x+3) = sqrt(2x-8) +1\nx+3 = 2x-8 +2 sqrt(2x-8) +1\n-x + 10 = 2 sqrt(2x-8)\nx^2 -20x + 100 = 4 ( 2x-8)\nx^2 - 28x  +132 =0\n'

are u sure its x2? shouldn't it be 2x+10x=(a number) usually there is a number at the end of the equation and u have 2 solve for "x". add details to ur question and then i may be able 2 help u.
