Answers by John L.

Sydni,            What you need to do is set up the proper equation. You do not know how much either Exxon or Wal-mart made, but you do know why one is different than the other. The question tells you why Wal-mart was different than Exxon, so...

Vanessa,              In order to answer this question you need two pieces of information. This first is how many degrees in a circle and how many minutes in an hour. The number of degrees in a circle/ by the number of minutes in a...

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...

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 =...

Regin,            6.5% can be written as a decimal. In order to do this move the decimal point 2 places to the left and remove the % sign. Therefore 6.5 is written .065 as a decimal. Then you can multiply 308,827,000 and .065 in order to find your...

Vanessa,              I would begin by asking you what, based on what you have studied so far, do think the answers to these questions are. Then we can take your ideas and frame them in a way that gives you a clearer understanding of...

Connor,            You can determine the percentage of increase ( or decrease) by setting up a simple proportion and then cross multiplying. The formula is:   difference between starting point and ending point/starting point...

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...

Morgie,              The formula to find the slope of a line is y2-y1/x2-x1 It does not make a difference which pair is 1 and which is 2. Let us call ( -85,11) pair 2 and (-78,10) pair 1 Therefore the slope is found by   11-10/-85...

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

Fanny,           To graph the first example you put one point at 4 on the x-axis ( the horizontal line ) and place the other point at 5 on the y-axis ( the vertical line ) then you draw a line that runs through each point. You follow the same method...

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.
