Answer:

A- Subtract 6 from both sides of the equation. The answer is b= 15.

For this equation, you need to do the opposite of the number in the same side of the variable. So, there is a +6. To get rid of the +6, you need to be -6.

6-6=0

21-6=15

You will be left with b on one side, and then 15 on the other side.

Answer:

D. Add 21 to both sides of the equation.

The answer is b = 198.

Check the solution by substituting 198 for b.

Step-by-step explanation:

D. 21-21= 177+21=198

198-21=177

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

$(\frac{\sum x_iL_i}{\sum L_i},\frac{\sum y_iL_i}{\sum L_i})$

Where ( $(x_i,y_i)$ represent the coordinates and $L_i$ 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

$\sum y_iL_i=65\times 2200+55\times 900+95\times 1300+200\times 1750+175\times 3100=1208500$

The sum of demanded units is

$\sum L_i=2200+900+1300+1750+3100=9250$

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

$y_0=\frac{\sum y_iL_i}{\sum L_i}$

$y_0=\frac{1208500}{9250}$

$y_0=130.6486$

$y_0\approx 131$

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

Inessa05 [86]

So first game
half were eliminated
we notice a pattern
first game=64 times 1/2
next game 32 times 1/2 so

so just multiply by 1/2 till you get 1
round 1 64/2=32
round 2 32/2=16
round 3 16/2=8
round 4 8/2=4
round 5 4/2=2
round 6 2/2=1

6 is the answer
