Answer:

a) m + n + e3 + ( -2n)  +  10m  =  11m - n + e3

b) x + 2y -4y + 6x + 2x = 9x -2y

c) a + b + c + 2a + 3c -2a + 3b + 4c = a + 4b + 8c

d) 2a  -b + 3c -2a + 3b + 2c = 2b + 5c

Step-by-step explanation:

En cada uno de los casos:

1) Reorganizas los términos

2) sumas los coeficientes de los términos semejantes

a)  m + n + e3 + ( -2n)  +  10m

1) Reorganizando los términos

m + 10m + n + ( -2n)  + e3

2) Sumando los coeficientes de los términos semejantes

(1 + 10) m + (1 - 2) n + e3

(11)m + (-1)n + e3

11m - n + e3

b)  x + 2y - 4y + 6x + 2x

1) Reorganizando los términos

x + 6x +2x + 2y - 4y

2) Sumando los coeficientes de los términos semejantes

(1 +6 +2) x + (2- 4) y

(9) x + (-2)y

9x -2y

c)  a + b + c + 2a + 3c -2a + 3b + 4c

1) Reorganizando los términos

a + 2a - 2a  + b + 3b + c + 3c + 4c

2) Sumando los coeficientes de los términos semejantes

(1 + 2 - 2 ) a + (1  +3) b + ( 1 + 3 +4) c

(1) a + (4)b + (8)c

a +4b + 8c

d)  2a -b + 3c -2a + 3b + 2c

1) Reorganizando los términos

2a - 2a - b + 3b + 3c +2c

2) Sumando los coeficientes de los términos semejantes

(2 - 2) a + (-1 +3) b + (3 +2)c

(0) a + (2) b + (5) c

2b + 5c

Answer:

Loss= $175

Loss %= 7%

Step-by-step explanation:

First of all, you find the difference between 2500 and 2325 which is 175, as his has decreased, it is a loss of $175

To find the percentage you do the difference over the original amount

So 175/2500 which will give you 0.07

0.07 x 100 will give you 7%

Option C a right triangle is the correct answer

Answer:

50

Step-by-step explanation:

70+60 =130

180-130 = 50 degrees

Answer: 50

Step-by-step explanation: Every triangle is 180 degrees so add the 60 and the 70 to get 130. 180-130=50. So 50 is your answer.

Answer:

$8000

Step-by-step explanation:  

Given: Car worth = $9,500, car loan = $7,400. Student loan = $6,000, savings account = $1500. The balance on her credit card is $3200.  

Formula: Total Assets - Total Liabilities - Intangible Assets = Tangible Net Worth.  

To find: Gale's net worth  

Solution: You can calculate your net worth by subtracting your liabilities (debts) from your assets.

Firstly, calculate the total amount of assets by adding them together;  

Total assets = Car worth + car loan + Student loan + savings account + balance on her credit card =  

$9,500 + $7,400 + $6,000 + $3200 =$26,100

Secondly, calculate the Liabilities by adding them together;  

Car loan + Student loan =  

$7,400 + $6,000 = $13,400

Then, calculate the Intangible Assets by adding them together;  

Savings account +  The balance on her credit card =  

$1500 + $3200 = $4700

Finally, subtract the total amounts;  

$26,100 - $13,400 - $4700 = $8000

(Note:- If your assets exceed your liabilities, you will have a positive net worth. Conversely, if your liabilities are greater than your assets, you will have a negative net worth.)

Answer:

2

Step-by-step explanation:

ΔX = -1 – 2 = -3

ΔY = -4 – 2 = -6

-6 divided by -3=2

Hope it helps ;)

Step-by-step explanation:

[tex]slope = \frac{y2 -y1 }{x2 - x1} \\ = \frac{ - 4 - 2}{ - 1 - 2} \\ = \frac{ - 6}{ - 3} \\ = 2[/tex]

even if x₁ = -1, y₁ = -4 and x₂ = 2, y₂= 2 the result remains the same.

Answer:

25m + 10b = 400

Step-by-step explanation:

Total amount that can be earned = $ 400

Amount earned on mowing a lawn = $ 25

Amount earned per hour on babysitting = $10

Amount earned for mowing one lawn is $ 25, so amount earned for mowing m lawns will be $ 25m

Amount earned for one hour of babysitting is $ 10, so amount earned for babysitting for b hours will be $ 10b

Total amount earned = Amount earned from mowing m lawns + Amount earned from babysitting for b hours

Using the values from above, we can set up the equation as:

400 = 25m + 10b

Answer: c. $9.00

Step-by-step explanation:

45 x .20 = 9.00

Answer:

It is D

Step-by-step explanation:

Within each coordinate it represents (x,y)

The x moves along the horizontal line and the Y moves along the vertical line.

For example: For (-5,5) move to the left 5 times, then move up 5 times.

A negative X goes to the left and a negative Y goes down.

A positive X moves to the right and a positive Y moves up.

Answer: The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.

Step-by-step explanation:

What is the probability of choosing a pen from the first box? It is 5/8.

What is the probability of selecting a crayon from the second box? It is 3/12 = 1/4.

The probability of picking a pen from the first box and a crayon from the second box is 5/8 x 1/4 = 5/32.

Answer:

40.25 yds to the the nearest 100th

Step-by-step explanation:

The diagonal forms a right triangle with the length and width.

The diagonal is the hypotenuse

So, let d = the diagonal distance

[tex]d^{2}[/tex] = [tex]18^{2} + 36^{2}[/tex]

   = 324 + 1296

   = 1620

d =  [tex]\sqrt{1620}[/tex] = 40.25 yds to the the nearest 100th

Answer:

slope = 4

y intercept = -3

Step-by-step explanation:

The equation is put in slope intercept form

Slope intercept form: y = mx + b

where m = slope and b = y intercept

looking at slope intercept form

4 is located where m should be , meaning that the slope is equal to 4 and

-3 is located where b should be , meaning that the y intercept is -3

Therefore the answers are the first and last option choices.
