Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x

Step-by-step explanation:

We have to simplify each expression for comparison

Expression 1:

$6x+18-3x-9\\= 3x+9$

Expression 2:

$6x-3(3x-3)\\= 6x-9x+9\\= -3x+9$

Expression 3:

$-3(x-3)\\= -3x+9$

Expression 4:

$-6x+3(3+3x)-6x\\= -6x+9+9x-6x\\= -3x+9$

Hence,

Equivalent expressions are:

6x-3(3x-3)

-3(x-3)

-6x+3(3+3x)-6x

Answer:

D 9.5

Step-by-step explanation:

Write data in increasing order.

3, 5, 5, 6, 6, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

Find the median

3, 5, 5, 6, 6, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

Median is 8

Lower half of the data is : 3, 5, 5, 6, 6, 6, 7, 7, 8, 8,

First quartile is the median of the lower half of the data=6+6 /2 =6

Upper half of the data is: 8, 8, 8, 9, 9, 10, 10, 10, 10, 11

The Third quartile is the median of the upper half=9+10 / 2 = 9.5

Help please (i pressed 0.09 by mistake)

Alja [10]

Answer:

The answer should be .25

Step-by-step explanation:

The answer should be .25 because:

- there are 4 places you can score and since you want it to land on 5 and there is only one 5 it counts as a 1

- the since there are 4 in total and you want to land on 1 you get 1/4 the number one standing for there only being one 5 and the 4 standing for the number of places to land on.

-then you convert the 1/4 into a decimal which makes .25

P = 215(1.005)t/3

Reil [10]

Answer:

(D) 36

Step-by-step explanation:

0.5% = 0.5/100 = 0.005

It is given that the population (215) is predicted to increase by 0.5%. To know the value after increment, 215 has to be multiplied by (1 + 0.005) or 1.005.

In the equation P = 215(1.005)t/3, the value of t/3 has to be equal to 1 for 0.5% increase.

t/3 = 1

t = 3 years

Convert years to months.

n = 3 ⋅ 12 months

n = 36 months

The correct option is D.

Thanks!
