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
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
