Answer:

Q = P - n(x/100)

Step-by-step explanation:

P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.

So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;

Q = P - n(x/100)

Describe how you would tell that two lines are parallel or coincide by looking at the equations of the lines in standard form.
Talja [164]
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel.

Unlike parallel lines, perpendicular lines do intersect. Their intersection forms a right, or 90-degree, angle.

You roll a number cube once.<br> what is the theoretical probability that you roll a 3 or 4?
yanalaym [24]

Answer:

2/6 or 1/3

Each number has 1 /6 probability. But since you can accept either 3 or 4, the probability is better and is 2/6 or simplified to 1/3.
