It would be: 18/15 * 100 = 1800/15 = 120%
The right answer is C)
Consistent and independent system of two linear equations is a system such that there is only one solution for the system, that is, the two straight lines cross at a point. So we can analyze each case and I have attached some graphs to provided you with examples. Those graphs aren't about the equations but it's about general cases:
A) Consistent and dependent. If we divide this given equation by 2 we get the same line. (See Figure 1)
B) Inconsistent. No solutions. (See Figure 2)
C) Consistent and Independent. (See Figure 3)
D) Consistent and dependent.
Answer = c
Step-by-step explanation:Since the medians are approximately the same they lost on average around the same amount regardless of exercise. Notice that the range of those with exercise is smaller though so they were more consistent in the amount of weight lost.
The answer should be 140, I hope this helps! Have a fantastic day!!

x=1, y=-4.
Solve for the first variable in one of the equations, then substitute the result into the other equation.
