2/5x -3 = -y
-2/5x + 3 = y
Inequality:
Let
x = pound/week weight loss by Reza
y = pounds/week weight loss by James
Therefore, after 10 weeks the two will weigh as follows:
Reza = 185 - 10x
James = 180 - 10y
But, Reza is said to be weighing less than James after 10 weeks. Then, the inequality will be as follows:
185 - 10x < 180 - 10y
Determination of the constraints:
Solving the inequality written above;
185 - 10x < 180 - 10y
185 - 180 < 10x - 10y
5 < 10(x-y)
0.5 < x - y
Therefore,
0.5 + y < x or x > 0.5 + y
It can be seen that, for Reza to weigh less than James after 10 week, the loss of weight by Reza must be more than half to the rate of weight loss by James.

Answer:
B. s = 0.85r
Step-by-step explanation:
The sale price is 15% off the regular price. In equation form, that is ...
s = r - 15%×r
s = r(1 - 0.15) = 0.85r
The equation that can be used to calculate the sale price is <em>s = 0.85r</em>.
