i am assuming you have written 3 and five tenths which is same as 35 /10 anyway.\nfirst we simplify this term to 7/2 \nnow the expression is 7/2 + 3/4\ntaking the LCM of the denominators 2 , 4 which is 4\nwe change 7/2 to an equivalent fraction with denominator 4 which is 14/4 \nnow the expression becomes\n14 /4 + 3/4 \nsince the denominators are now the same we just add the numerators to get the answer \n14 /4  + 3 / 4 = 17 / 4\nwhich can be written as 4 and 1/4 or 4  1/4

Your ratio is 1:8.15          You fid this out by starting at 13:106 and work yoiur way down to 1. \n\nyou divide both sides by 13 to get your answer.

go to the website listed below. you fill in the information and it will calculate it for you!!

There is no simple trick for the addition of two numbers. You will have to calcuate their actual value and then add them. So for you example you would have to go to 4 + 8 = 12.

I'm pretty sure it's the same as multiplying 2 fractions.  You just multiply across the top, then across the bottom, or in w/e order you like, and what you get is your answer.

SOrry, I can't help you. If I had the formulas I could do it, but there is no way I remember that off the top of my head! Good luck

You figure the square root of each number separately...you've probably learned that in class alredy (how to do that)...then you take reach result, and multiply them together for your final answer.\n\nUse your textbook for reference...good luck!

Well i cannot write the whole formula here but check the link below

T=m1*-9.8+m1*a\nT=m2*a--m2*-9.8\n\nset them equal and solve for a\n\ntrust me, i had a test on this today

Set up an equation:\n\n72 = .6 * X\n\n72/.6 = X\n\nX = 120

I'm sorry, but how could you not know this?\nThis is basic elementary math and if you don't know how to round you are in trouble.\nIt's 0.1 by the way

(assuming the second 2 is an exponent) 2*2*2*7*5*g*h*h \nyou really should learn to do this if you are ever going to get through school though

You're NOT dumb!  Everyone has different skills.  Thought you were going to send me a note when you got stuck??  I took alg II twice!\n\n1.  simply switch it to s=1-2t.  Now put that first one into the second , for s, which will give you the value of t when you solve it.  Plug in t's value into either and that will give you s.\n\n2.  do the same way\n\n3.  P=120\n     L=3w\n     P=L times W\n\n4/5:  take the number on the outside and multiply each number inside the (), then combine.\n\n7/8:  isolate the variable (letter) and get it just on one side

Remember for numbers 0-4 you round down, for numbers 5-9 you round up. \nA. $90\nB. $4.56\nThese are just to explain. You can do the rest yourself. If you really don't get it speak to your mom, dad, or teacher, you need help.

Simply multiply\n9 * 8 * 7 * 6\nBecause the first number can be 1-9 but not zero and the second number can be 1-9 but one number has already been used and so on and so forth.\nHope it helps.
