You can multiply 0.129 and 0.3 by 10 each to make it a little easier to see what to do.
0.129 / 0.3 = 1.29 / 3
Simple long division will take you to 0.43
I got it! the Brass would cost $6 each and the Steel Parts would cost $3 each so if you were gonna buy 10 Brass and 13 Parts it would cost $60 for the brass and $39 for the Parts. So $60+$39= $99 And the answer is C
Answer:
Speed of the plane from Washington: 
Speed of the plane from LA: 
Step-by-step explanation:
We need to remember that:

Where "d" is distance, "V" is speed and "t" is time.
Let be "w" the speed in mph of the plane from Washington and "l" the speed in mph of the plane from LA.
We know that the distance between the cities is 2700 miles and after they flied for 2 hours, the distance between them was 500 miles. Then we can write the following equation:
[Equation 1]
Since the speed of the plan from LA was 100 mph faster, we can write this equation:
[Equation 2]
The steps to solve this are:
1. Substitute the Equation 2 into the Equation 1 and solve for "w":

2. Substitute the value of "w" into the Equation 2 in order to find "l":
Answer:
M=(2,1)
Step-by-step explanation:
The mid points is half the distance of the x and y values so
-4 and 8 are 12 apart so 12/2=6 so -4+6=2
so the x value of M is 2
same for the y value 6 and -4 are 10 apart 10/2=5 and 6-5=1 so
so the y value of M is 1 so
M=(2,1)
