Hello Alice,    Whenever two fractions are equal to each other, we can always "cross multiply"  and get an equivalent equation.  Thus, 6/(n-4)=10/n becomes 6n=10(n-4), now  distribute the 10 on the right

Let x=the cost per tennis racquet, and y=the cost per pair of tennis shoes.    Thus, we get:  1. 150x + 50 y = $14,000  and  2. 80x + 30y = $7,650    We can simplify each... 1. divide through by 50, 2

Assuming the 128 ft/sec is vertical (i.e. straight up), then...  h(t)=128t-16t^2 gives the equation of motion in the vertical direction  (i.e. the height above the ground).  Since this is a parabola, we

2015-01-23 A factoring question:

Hello Tressa,    Consider this problem:  2x+6y-2=2(x+3y-1), yes?    Now look at: (1/2)x+(3/2)y-1/2=(1/2)x+(1/2)*3y-(1/2)*1,  now factor the common factor of 1/2 (just like in the above problem we factored
