Answers by John L.

Cassie,            Set up a proportion  where 35/245 ( liters/miles ) = 100/x. ( liters/miles) Then cross multiply 35x =245 times 100. Then divide both sides  by 35 to obtain your answer.  I hope this is helpful.  ...

Michael,              you set up a proportion , two equal fractions or ratios. In this case- 2/N = 10/6   then you cross multiply -2 x 6 = 10 x N   which gives you- 12 = 10N     to find...

-4(5w+x)+5(x-3w) (answer)

Ronda,            You would begin by clearing out your parenthesis. You would multiply both 5w & x by -4 and then you would multiply both x & 3w by 5 this would look like this:   (-4)(5w) + (-4)(x) + (5)(x) - (5)(3w)...

Maria,          The first thing you want to do is isolate your variable by subtracting 3x from each side of the equation. This will leave you with -2x = -6. After that divide each side of the equation by the coefficient ( in this case -2 ). When you...

Kassandra,                   This is a subjective question. Your opinion is just as valid as anyone else's. I would start by listing reasons why you feel that the Cold War raged throughout the 50's and 60's...

Lili,          A Circle consists of 360 degrees. So if you have an angle that is created by two radii with a vertex at the midpoint that covers ,for example, 1/4 of the circle the angle would measure 1/4 of 360 degrees. You can do the math.   I...

Mickey.             I am working on the premise that we are speaking about 1 1/2 hours.   You can solve a  question dealing with distance ,time and speed by using the formula   D=RT where D =...

Abby,        An ordered pair is written (x.y) so in this case x = -1 and y = -8 So your equation is -8 =-1-5. If this is a true statement it is a solution. if it is not true then it is not a solution. does -8 = -1-5?   Hope this helps

Arie,             An absolute value question requires two answers because 2 numbers will have the same absolute value. For instance, both 5 and -5 have an absolute value of 5.   So the 2 equations you use are 4x + 6...

Amy,          What is the question? Do you need to come up with the equation for the line? If so, in which form?

Alli,        Just like in the previous question you begin by dividing both sides of the equation by the coefficient, in this case 5.2     13/5.2 = 5.2x/5.2   x= You should be able to take it from here    ...

12x equals 72 (answer)

Alli,        Your goal is to find out what 1x would equal. You do this by dividing both sides of the equation by the coefficient ( the number in front of the variable) In this case  12x/12 = 72/12     x=6  The way you check this...

Mishell,           If the scale factor is 1/4, you multiply each coordinate by 1/4.  For example, (-12,16) would become -3,4). I hope this helps.
