PLEASE HELP ASAP!!!!!!!!!!!!

Answer:

[tex]11+i[/tex]

Step-by-step explanation:

So we have the expression:

[tex](6-3i)+(5+4i)[/tex]

Remove the parentheses:

[tex]=6-3i+5+4i[/tex]

Combine like terms:

[tex]=6+5-3i+4i[/tex]

Add:

[tex]=11+i[/tex]

This is in standard form. a is 11 and b is 1.

And we're done!

Answer:

see below (I hope this helps!)

Step-by-step explanation:

To get rid of the coefficient of w, 3/2 in this case, we must divide the entire equation by 3/2, which is the equivalent of multiplying the entire equation by 2/3. Doing this, we get:

3/2w * 2/3 = -20 * 2/3

w = -40/3 = [tex]-13\frac{1}{3}[/tex]

x = -3

y = -4

Hope that helped :)

Answer:

Step-by-step explanation:

80% = 80/100 which also = 4/5

so the price was reduced by 4/5

20 minus 4/5 is = to  20 minus 16/20

which is 20/20 minus 16/20 = to 4/20

simplified is 4 dollars

Answer:

The ratios are equivalent.

Step-by-step explanation:

If you multiply both 5 and 6, the ratio stays the same.

5:6 = 10:12 = 15:18 = 20:24 etc.

You can try this by dividing the larger number by the smaller number. You'll always get 1.2 as the "relationship", or ratio, is preserved.

24/20 = 1.2

15/18 = 1.2

10/12 = 1.2

6/5 = 1.2

Answer:

The missing variable r = 3

Step-by-step explanation:

C = 2πr

Where,

C = 18.84

π = 3.14

r= ?

The missing variable is r

C = 2πr

Making r the subject

r = C / 2π

= 18.84 / 2*3,14

= 18.84 / 6.28

= 3

r = 3

The missing variable r = 3

Check:

C = 2πr

18.84 = 2*3.14*3

18.84 = 18.84

=>2 9/50

Answer:

2 9

/50

Step-by-step explanation:

Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there are  2  numbers to the right of the decimal point, place the decimal number over  10

^ 2

(

100

)

. Next, add the whole number to the left of the decimal.

2 18/100

Reduce the fractional part of the mixed number

Answer:

Se refieren a las unidades de tiempo del sistema sexagesimal

9:25 son 9 minutos y 25 segundos

33:41:38 son 33 horas, 41 minutos y 38 segundos.

Step-by-step explanation:

El sistema sexagesimal se utiliza para medir tiempos y ángulos.

El tiempo se mide en horas,minutos y segundos

En cambio, los ángulos se miden en grados,minutos y segundos.

Los dos puntos '':'' sirven para separar las unidades.

La base de este sistema es el número 60 :

60 segundos ⇒ 1 minuto

60 minutos ⇒ 1 hora

Eso en cuanto a tiempo

En cuanto a grados :

60 segundos ⇒ 1 minuto

60 minutos ⇒ 1 grado

Cuando tengo dos números como en 9:25 , el número de la derecha corresponde a los segundos y el de la izquierda a los minutos

Entonces, 9:25 son 9 minutos y 25 segundos

Por otro lado, cuando tengo 3 números, como en 33:41:38, el número de la derecha corresponde a los segundos, el de en medio al de los minutos y el de la izquierda al de las horas (si nos referimos a unidades de tiempo).

Entonces, 33:41:38 son 33 horas, 41 minutos y 38 segundos.

=x = 2.5

Answer:

6x +2x

Step-by-step explanation:

when the number= x, you can just form the equation as per usual. 6x = a number times 6; 2x = a number times 2.

x is used bc the number is an unknown value. only x can be used bc it is stated the same number. hsing different alphabets such as y or z indicates the unknown value ia different.

Answer:

Step-by-step explanation:

This works because of the method called "foil"

Answer:

x=1

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

7x−(6x−1)=2

7x+−1(6x−1)=2(Distribute the Negative Sign)

7x+−1(6x)+(−1)(−1)=2

7x+−6x+1=2

(7x+−6x)+(1)=2(Combine Like Terms)

x+1=2

x+1=2

Step 2: Subtract 1 from both sides.

x+1−1=2−1

x=1

Step-by-step explanation:

The volume of cube 4x².

Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it can occupy in three dimensions.

We have,

Edges of cube as = 4 , x and x.

So, volume of cube

= 4 x (x . x)

= 4 . x²

= 4x²

Thus, the volume of cube 4x².

Answer: Mrs Bell

Step-by-step explanation:

From the question, we are informed that Mrs. Bell has an interest rate of 4.175% = 0.04175 on her house and Mr. Bentley has an interest rate of 4.25% = 0.0425 on his house.

The person who has the lower interest is Mrs Bell. This is because 4.25% is higher than Mrs Bell's interest of 4.175%

Answer:

The answer is D

Step-by-step explanation:

Mrs bell has the lower interest rate because both decimals have a 4 in the ones place, and 1 tenth is less than 2 tenths.

Answer:

The first two pairs of functions are inverse of each other

Step-by-step explanation:

Inverse functions?

1...................................

f(x) = {(-5, -9), (-3, -4), (0,1), (3,7), (6,13)}

g(x) = {(-9,-5), (-4, -3), (1,0), (7,3), (13,6)}

2...................................

f(x) = x + 7 is given

Inverse of f(x) is

Since g(x) = x - 7 it is inverse with f(x)

Data of f(x) and g(x)

x = {2, 3, 4, 5}      f(x) = {3, 8, 15, 24}

x = {5, 4, 3, 2}      g(x) = {24, 15, 8, 3}

Answer:

D.5

Step-by-step explanation:

You can write the following equations from the information given:

y=x+3 (1)

11x+5y=47 (2)

x is the number of hardback books

y is the number of paperback books

You can replace (1) in (2):

11x+5(x+3)=47

11x+5x+15=47

16x=47-15

16x=32

x=32/16

x=2

Then, you can replace the value of x in (1) to find the value of y:

y=2+3

y=5

According to this, the answer is that Jamal bought 5 paperback books.
