Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation.
So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation. And since x + y = 8, you are adding the same value to each side of the first equation.
The speed for which Brian iron the shirts is given by:
Rewriting we have:
Then, for each minute, we have the amount of ironed shirt is:
Answer:
At this rate, Brian plans 10/162 of his shirt.
Answer:
A
Step-by-step explanation:
Well automatically we can eliminate B and D because they make no sense whatsoever. So that leaves us with A and C. A is telling us to find the mean so it has to be that one. So, with procces of elimination the answer has to be A. I know this because the owner needs to find an average to see how many bottles he will have sold daily. ;) Your very much welcome
Answer:
The bigger angle is 144 degrees and the smaller one is 36 degrees
There's a lot of information missing here, and the given list of choices is basically incomprehensible.
Suppose J (a, b) and K (c, d) are two points in the plane. We can trace out the line segment JK joining these points with the function
r(t) = (1 - t) (a, b) + t (c, d)
where 0 ≤ t ≤ 1.
Let P be the point that divides JK into line segments JP and PK having a length ratio of 2:5. Then JP is the point 2/7 of the way along JK, so that the coordinates of P are
P = r(2/7) = 5/7 (a, b) + 2/7 (c, d) = ((5a + 2c)/7, (5b + 2d)/7)
and in particular the x-coordinate of P is (5a + 2c)/7.
