Answers by Ralph L.

since we have two repeating numbers, which are (97), there are also two 9s in the denominator:   so,   3 + 97/99 = 3 97/99

since you only have one repeating number (2) the denominator is composed of one 9 only.   2/9

y = -x + 3,     (-2,-2)   we know that the above equation is in the form: y = mx + b, where m is the slope. Any line parallel to the given line will have the same slope (m = -1). To find the equation of the parallel line we use the slope and the point given...

Not enough info. You are not given pages per chapter so you won't know how many pages the book has.    

you will need 26 * 31 = 806 employees. The age has nothing to do with the problem.

we have equation -4x + 3y = 24   to find x-intercept, plug in 0 to y:  -4x + 3(0) = 24 ----->-4x = 24 -----> x = -6   so x-intercept is (-6,0)   to find y-intercept, plug in 0 to x: -4(0) + 3y = 24 ----> y = 8   so y-intercept...

    4(1/C + 2/C) = 1   (1/C + 2/C) = 1/4   3/C = 1/4   C/3 = 4   C = 12   Since Julissa is twice faster than Chris, Julissa can do the job at half of Chris' time (1/2 * 12 = 6 hours)   Chris can...

Let x be the number of 4 point questions, so number of 2 point questions is 40 - x:   120 = 4x + 2(40 - x)   120 = 4x + 80 - 2x   120 = 2x + 80   120 - 80 = 2x   40 = 2x   x = 20   there are 20...
