Hi Mercedes!  Try to write down what you know...   First, name things with single letters.  For example, let's name each side of the square as "s", and each side of the triangle as "t" (easy to remember t=triangle and s=square :-) Now translate "side...

Hi Kiona, as I bet you already know, point coordinates (locations on the X and Y axes of a graph) are listed as X first, then Y.  The first set (5,3) means at that point, X=5 and Y=3.  The second set (5,-3) means that X=5 and Y=-3 Usually the X-axis is a horizontal line, and the Y-axis...

Another way, using Simultaneous Equations: Numbers of tickets: Student (s) tickets + General Admission (g) tickets = 450, or s + g = 450 Numbers of dollars: 4s + 6g = 2340   4s + 6g = 2340 s + g = 450. Multiply the bottom equation by -4: -4s - 4g = -1800 Now...

133=-7(1-4k) (answer)

Hi Judy... I think you can do this... First, multiply the -7 times each term inside the parentheses (-7*1, then -7*-4k) Add the opposite sign of what doesn't have a "k" in it, such as -7, to both sides of the equation.  So if you have a -7, then add +7 to that, and...

Assuming the original problem is:  [(m/4)*(n/3)]-1 divided by [(-5m/-3)*(n4)]2   = 1 divided by [(mn/12)] [(5mn4/-3)2] = 1 divided by (mn/12) (25m2n8/9) = 1 / (25m3n9/108) = 108 / 25m3n9

Make a simple list of what you will be tested on, first by subject, then by topic under each subject. Prioritize that list - use a highlighter (or similar) to clearly mark which you think will be the most important subjects and topics Look at only the highlighted ones:  which of these...

Teri, I think you can do this:  first multiply what's outside with parentheses with the terms inside them:   7*2b - 7*5 = 14b - 35 Now put that with the rest:  14b - 35 + 3 = 10, or 14b -32 = 10, or 14b = 10 + 32  (added 32 to both sides) 14b = 42 b...

For the original problem of 3x = 7 - 5x: First, get all the x's together, by adding or subtracting the same term from both sides of the equation, to keep it balanced:  Let's add 5x to both sides:  3x + 5x = 7 - 5x + 5x Do the addition:  8x = 7 Now get x by itself:...

Anytime you see a fraction, it means "divide the top number (numerator) by the bottom number (denominator)" In this case, that's -2/9 = -2 divided by 9 = -0.22222.... (repeating forever).  If the top and bottom have the same sign (both are positive, or both are negative), then...

No one really knows what the inside of a black hole is like, or consists of.  Most astrophysicists believe that all molecular and atomic structure as we know it is destroyed, and instead we have sub-atomic particles, including quarks, and probably strings (if string theory is ever proven)...

Hi Imari...   just get x by itself, in two steps:   (1) Subtract 4 from 4-6x.  And we have to also do that to the other side of the equation, to keep it balanced and both sides equal:  4-6x-4 = 82-4;   now 6x = 78 (2) Now we can divide both sides of the...

I read your question as  [(3x+9) / (2x-6)] * [(4x+4) / (x+3)].  Assuming that's correct: Multiply both numerators and both denominators:   (12x2 + 12x  +36x + 36) / (2x2 + 6x - 6x - 18) = (12x2 + 48x + 36) / (2x2 -18).   Factor:...
