Answer:

They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.

Answer:

7

Step-by-step explanation:

the median is the middle and if you order them

4,5,6,8,8,9 then you remove one from each side until you have 6,8 so you go in-between the two (seven)

Answer:

7

Step-by-step explanation:

You need to arrange the numbers in an increasing order:

4 5 6 8 8 9

then you need to count how many values we have in the specific set:

6 total values

now we need to find the middle of our set

4 5 6 II 8 8 9

and then we divide the two numbers next to the middle part (6;8) and divide them by 2

(6+8):2=7

Step-by-step explanation:

6x - 15 = 75, 6x = 90, x = 15.

2(2x - 1) = 46, 2x - 1 = 23, x = 12.

x + (x - 10) = 26, 2x = 36, x = 18.

5x - 3x = 10, 2x = 10, x = 5.

Hence the equations

in increasing order of x-values are:

5x - 3x = 10,

2(2x - 1) = 46,

6x - 15 = 75, and

x + (x - 10) = 26.

Answer:

5x - 3x = 10

2(2x - 1) = 46

6x - 15 = 75

x+(x - 10) = 26

Answer:

elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.

  In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.

  That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

Answer:

The rate of the boat is 75.17 km/h and the rate of the stream is 17.83 km/h

Step-by-step explanation:

System of Equations

Let's call:

B = speed (rate) of the boat in still water

S = speed (rate) of the stream

The boat travels 172 km in 3 hours when going upstream, that is when the speed of the stream subtracts its own speed. The speed is the distance divided by the time, thus:

[tex]\displaystyle B-S=\frac{172}{3}[/tex]

Multiplying by 3:

3B - 3S = 172        [1]

The boat travels 372 km in 4 hours downstream when the speed of the current adds to its own:

[tex]\displaystyle B+S=\frac{372}{4}=93[/tex]

B + S = 93

Solving for B:

B = 93 - S       [2]

Substituting in [1]

3(93 - S) - 3S = 172

Operating:

279 - 3S - 3S = 172

279 - 6S = 172

Subtracting 279:

- 6S = 172 - 279

- 6S = -107

Multiplying by -1 and solving for S:

[tex]S = \frac{107}{6}\approx 17.83\ km/h[/tex]

From [2]:

[tex]B = 93 - \frac{107}{6}[/tex]

[tex]B=\frac{451}{6}\approx 75.17\ km/h[/tex]

Answer:

the answer Is D.2

Step-by-step explanation:

9 is greater than 7 by 2

Answer:

Step-by-step explanation:

4/5 + 1/3 = 17/15 decimal form: 1.13 mixed number form: 1 2/5

1/2 + 2/5 = 9/10 decimal form: 0.9

3/4 + 7/10 = 29/20 decimal from: 1.45 mixed number form: 1 9/20

5/6 + 3/5 = 43/30 decimal form: 43/30 decimal form: 1.43 mixed number form: 1 13/30

1/5 + 1/4 = 9/20 decimal form: 0.45

1/4 + 5/9  = 29/36 decimal form: 0.805

2/3 + 7/8 = 37/24 decimal form: 1.5416 mixed number form: 1 13/24

Answer:

9.0, 9.012, 9.201, 9.210

Step-by-step explanation:

9.0 has no decimal numbers, so it goes at the beginning, 9.012 is the next greatest, then 9.201, and finally, 9.21. Also, a zero at the end of a decimal number adds nothing.

Answer:

The total number of cookies is 90

Step-by-step explanation:

As, they said 40% of the total number of cookies is 36, we will take the total as "x"

= 40% of x = 36

40/100 X x = 36

40x = 36 x 100

40x = 3600

x = 3600/40

x = 90

So total cookies she baked = 90

Let's check!

So 40% of 90 need to be 36

So,

40/100 x 90 = 3600/100

= 36

So therefore, total number of cookies = 90

Answer: H2O is the answer

Answer:

Step-by-step explanation:

to solve this system of equations we will add them

x-3y=-12

2x+3y=3 now +3y-3y=0

3x=-12+3

3x=-9

x=-3

plug in the first equation

-3-3y=-12

-3y=-12+3

-3y=-9

y=3

Answer:

8.25

Step-by-step explanation:

(-10,-7) (-8,1) find the distance between the two points show work.

The formula for calculating the distance between the two points is expresses as;

D = √(x2-x1)²+(y2-y1)²

D = √(-8+10)²+(1+7)²

D = √(2)²+8²

D = √4+64

D = √68

D = 8.25

Hence the distance between the two points is 8.25

Answer:

point K is reflected across the y-axis to create point K'

Answer: 26.7m

Step-by-step explanation:

Since a decagon has 10 sides, you'll have to divide 267m by 10.

267÷10= 26.7

One side of the decagon is 26.7m

Answer:

30%

Step-by-step explanation:

Answer:

15%

Step-by-step explanation:

To determine the percentage of the girls with blonde hair...it means we will have to use this formula

Number of girls with blonde hair/total numbers of girls ×100

Number of girls with blonde hair is 12

Total number of girls is 80

Therefore,12/80 ×100

1200/80

120/8

15

Therefore the percentage of the girls with blonde hair is 15%
