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)<u> Reorganizando los términos</u>

m + 10m + n + ( -2n)  + e3

2) <u>Sumando los coeficientes de los términos semejantes</u>

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

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

11m - n + e3

__________________

b)  x + 2y - 4y + 6x + 2x

1)<u> Reorganizando los términos</u>

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

2) <u>Sumando los coeficientes de los términos semejantes</u>

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

(9) x + (-2)y

9x -2y

__________________

c)  a + b + c + 2a + 3c -2a + 3b + 4c

1)<u> Reorganizando los términos</u>

a + 2a - 2a  + b + 3b + c + 3c + 4c

2) <u>Sumando los coeficientes de los términos semejantes</u>

(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)<u> Reorganizando los términos</u>

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

2) <u>Sumando los coeficientes de los términos semejantes</u>

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

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

2b + 5c

How do i know when to add or subtract in an angle equation?
madam [21]

Answer:

17

Step-by-step explanation:

< ABD = <ABC + < CBD

Substitute in what we are given

87 = 9x-1 +   6x+58

Combine like terms

87 = 15x +57

Subtract 57 from each side

87-57 =15x +57-57

30 = 15x

Divide by 15

30/15 =15x/15

2=x

We want to find <ABC

<ABC = 9x-1

         = 9*2-1

         =18-1

      =17

Joan pays 456.25 monthly on her mortgage. If her annual insurance premium is 1,560 and her annual real estate tax is 1,890, what
defon
The combined payment is 743.75.

The annual amount of insurance is 1560.  Dividing this by 12 gives us the monthly amount paid:
1560/12 = 130.

The annual real estate taxes are 1890.  Dividing this by 12 gives us the monthly amount paid:
1890/12 = 157.50

We add these to the monthly mortgage payment to find the total amount:
456.25+130+157.50 = 743.75
