Answer:
Step-by-step explanation:
Givens
d1 = d
d2 = 75 - d
r1 = x
r2 = x + 7
t = 3
Equation
x*t + (x + 7)*t = 75
This equation represents the total distance travelled. Neither one of the cyclists have gone 75 miles, but they both have gone distances that equal a total of 75 miles.
Solution
3x + (x + 7)*3 = 75
3x + 3x + 21 = 75
6x + 21 = 75
6x = 54
6x/6 = 54/6
x = 9
Answer
The first cyclist is going 9 miles / hr
The second cyclist is going 16 miles / hour
Answer:
-7-y1=-4(2-x1)
Step-by-step explanation:
Point slope form is like this: y-y1=m(x-x1) where y is the y value, x is the x value, and m is the slope. You plug the values in.
Answer:
576 People
Solving:
If the total number of people that downloaded songs from the site ( 100% ) equals "x," and 60% of "x" plus 384 equals "x," 384 must be 40% of "x" to add up to 100% ( the percentage of people "x" represents ).
384 / 40% = 960 = x
x = 0.6 ( x ) + 384
960 = 0.6 ( 960 ) + 384
960 * 60% = 576 people
