-4 = r/20 - 5

Add 5 to both sides

1 = r/20

Multiple by 20 on both sides

20 = r

Answer:

r = 20

Explanation:

-4 = r/20 - 5

  • Simplify both sides of the equation

-4 = r/20 - 5

-4 = 1/20r + -5

-4 = 1/20r - 5

  • Flip the equation

1/20r - 5 = -4

  • Add 5 to both sides

1/20r - 5 + 5 = -4 + 5

1/20r = 1

  • Multiply both sides of the equation by 20

(20)1/20r = 1(20)

  • r = 20

1) Answer: 21
As y varies directly with x, this means that the ratio y/x is always a constant.
In other words, the equation can be written as y = kx, where k is a constant term.

Thus, -\frac{14}{4} = -\frac{y}{6}
y = 21

2) Answer: C
Exactly the same process as above.
Here's another method:
25 = k(140)
k = 25/140 = 5/28

Thus, when y = 36, 36 = kx
36 = 5/28(x)
36 * 28/5 = x; x = 201.6

3) 9 = k(12)
9/12 = k and k = 3/4

4) On the graph, it hits y = 1 at x = 4.
Thus, we can rewrite the equation as:
y = (1/4)x, where the constant term is 1/4

5) y = kx
The distance represents the x-ordinates, and the time represents the y-ordinates.

9.5/475 = 0.02
4 = 0.02(x), in hours.
x = 200 miles.
