Answer:
x = 2
Step-by-step explanation:
Answer:
30
Step-by-step explanation:
Original Equation: 2(7 + 8)
So you have to multiply 2 by 7 which equals 14
Then you multiply 2 by 8 which equals 16
Your equation should now look like this: 14 + 16
Add 14 and 16 together.
Your answer is 30

Answer:
D.(2,-1,-1)
Step-by-step explanation:
-a+4b+2c=-8
3a+b-4c=9
b = -1
Substitute b=-1 into the other equations
-a -4 +2c = -8
3a -1 -4c =9
Multiply the first equation by 2 so we can eliminate c
-2a -8 +4c = -16
Add this to the second equation
-2a -8 +4c = -16
3a -1 -4c =9
-----------------
a -9 = -7
Add 9 to each side
a-9+9 = -7+9
a =2
b=-1
Now we need to find c
-a +4b +2c = -8
-2 -4 +2c = -8
-6+2c = -8
Add 6 to each side
-6+6 +2c = -8+6
2c = -2
Divide by 2
2c/2 = -2/2
c=-1

1 kilometer = 1000 meters.
Multiply total kilometers by 1000:
108 kilometers x 1000 = 108,000 meters.
1 hour = 3600 seconds.
Divide total meters by 3600:
108,000 / 3600 = 30 meters per second
Multiply 30 meters per second by 15 seconds:
30 x 15 = 450 meters in 15 seconds.
Answer:
The correct option is 2.
Step-by-step explanation:
According to the the center-of-gravity technique, the coordinates of the center-of-gravity location are

Where (
represent the coordinates and
is demand.
We have to find the Y-coordinate of the center-of-gravity location.
The sum of product of demand and corresponding y coordinates is

The sum of demanded units is

The Y-coordinate of the center-of-gravity location is




The Y-coordinate of the center-of-gravity location is 131. Therefore the correct option is 2.
