Answer:

b=-2

Step-by-step explanation:

-(-b+5)+5b=-19-b

b-5+5b=-19-b

b+b-5+5b=-19-b+b

2b-5+5+5b=-19+5

2b+5b=-14

7b=-14

7b/7=-14/7

b=-2

Step-by-step explanation:

Absolute values (|x|) just make the number inside positive so 9.9 > 1.4

Answer:

-5 ≤ n ≤ 3

Step-by-step explanation:

Firstly we solve the equation two at a time;

5n + 17 ≥ n - 3

5n - n ≥ -3 - 17

4n ≥ -20

n ≥ -5

-5 ≤ n

n - 3 ≥ -15 + 5n

n - 5n ≥ -15 + 3

-4n ≥ -12

-n ≥ -3

n ≤ 3

Therefore,

5n+17 ≥ n–3 ≥ –15+5n, becomes

-5 ≤ n ≤ 3

Answer: 7/3

Step-by-step explanation: From the leftmost, lower point to the uppermost point, you move upwards 7, and rightward 3. Slope is vertical movement over horizontal, giving 7/3.

Answer:

slope = -7/4

Step-by-step explanation:

Plug the points into this formula: [tex]\frac{y2 - y1}{x2 - x1}[/tex]

Plug in

[tex]\frac{-2 - 19}{8 - (-4)} \\\\\frac{-21}{12} = -7/4[/tex]

The simplest form is -7/4

Answer:

x=6, -6

Step-by-step explanation:

take the root of both sides then solve

Answer:

x = 18

Step-by-step explanation:

2x + 3(4) - 1 = 47

Begin by combining your like terms

2x + 12 - 1 = 47

2x + 11 = 47

Isolate your variable (x) by using inverse operations

2x = 36

x = 18

Answer:

Step-by-step explanation:

P + 4.5 = - p + 5

Bringing like terms on one side

P + p = 5 - 4.5

2p = 0.5

p = 0.5/2 = 0.25

In my opinion the answer is one solution

Answer:

1 solution.

Step-by-step explanation:

1/2(2p + 9) = -p + 5

lets solve for p

1/2 * 2p + 1/2 * 9 = -p + 5

1p + p + 9/2 = - p + p + 5

2p + 9/2 = 5

Multiply by 2 on both sides to get rid of the fraction 9/2.

4p + 9 = 10

4p = 1

p = 1/4

Therefore, there is only 1 solution.

You can now check by plugging in 1/4 for p in the original equation.

Answer:

El club tiene 84 miembros.

Step-by-step explanation:

El mínimo común múltiplo (mcm) es el número positivo más pequeño que es múltiplo de dos o más números. Es decir, el mínimo común múltiplo de dos números a y b es el número más pequeño que es múltiplo de a y múltiplo de b. Recordar que los múltiplos son el resultado de multiplicar un número por todos y cada uno de los números naturales.

Para calcular el mcm se descompone los números para escribirlos como un producto de números primos. Para descomponer un número se divide el número sucesivamente entre números primos hasta llegar a 1.  La descomposición es el producto de las potencias de los números primos, siendo sus exponentes el número de veces que se ha dividido por dicho primo.

El mínimo común múltiplo se obtiene escogiendo todos los factores (comunes y no comunes), elevados a la máxima potencia. Es decir eliges todos los factores, pero los que se repitan serán elevados a la máxima potencia.

En este caso, los miembros de un club social se pueden agrupar, sin que ninguno quede suelto, por parejas, por tríos y por grupos de 7. Para calcular la cantidad de miembros que tiene el club, entonces debes calcular el mcm entre los números 2,3 y 7

No podemos descomponer los números como producto de primos porque ya son números primos., por lo que el mínimo común múltiplo es el producto de comunes y no comunes al mayor exponente:

mcm (2,3,7)= 2*3*7= 42

Pero sabes que los miembros son más de 80 pero menos de 90, por lo que calculas un múltiplo del mcm obtenido.

Múltiplo de 42= 2*42= 84

El club tiene 84 miembros.

Answer:

11.4 and/or 11 2/5

Step-by-step explanation:

You can turn 22 4/5 into a decimal which is 22.8 and divide that by 2 and it gets you 11.4. You can also turn 22 4/5 into an improper fraction which is 114/5. Multiply that by 1/2 which is 11 2/5.

Answer:

3"x4

Step-by-step explanation:

The symbol for a foot is "ft", sometimes denoted by a prime(') , also, the inch is denoted by a double prime(").

Given

2 1/2inces (2.5") blue print represents 10ft living room

We are told that the dimension of the room on the blueprint is

12'x16'

Let us convert 12' to inches

So

2.5" represents 10'

X ' will be 12'

Cross multiplying

X=(2.5*12)/10

X=3"

Let us convert 16' to inches

So

2.5" represents 10'

Y ' will be 16'

Cross multiplying

Y=(2.5*16)/10

Y=4"

the dimension of the blue print is

3"x4"

Answer:

6 laps

Step-by-step explanation:

46 Divided by 7 is 6

Answer: 6 Laps

Step-by-step explanation:

Pretty simple to solve. Just divide 42 minutes and the first lap of 7 minutes to get 6 laps.

The answer is 63

Glad I could help :)

Answer:

117

Step-by-step explanation:

angle 2 is a vertical angle to 63. This means that it is equal to 2. So angle two is 63 degrees.

angle 2 and 7 add up to 180 degrees. You know that angle 2 is 63 degrees. So you do 180-63 degrees which leaves you with 117 degrees. Angle 7 is 117 degrees.

angle 5 and 7 are also vertical angles. Which means 5 is also equal to 117.

The answer is 117 degrees.

*Note that I'm assuming the prism is a triangular prism

Volume = 60cm³

Height = 6cm

Width = 2cm

The equation for the volume of a triangular prism is:

V = [tex]\frac{b * h * l}{2}[/tex]

Let's substitute in the values we already know:

60 = [tex]\frac{2 * 6 * l}{2}[/tex]

And now we need to make l the subject by multiplying both sides by 2:

120 = 2 x 6 x L

Simplify:

120 = 12L

Flip to make easier to read:

12L = 120

Divide both sides by 12 to get the value of L (length):

L = 10

And let's show proof that L = 10 (remember that V (volume) should be equal to 60):

V = [tex]\frac{2 * 6 * 10}{2}[/tex]

V = [tex]\frac{120}{2}[/tex]

V = 60

Therefore we can determine the the length is indeed 10cm.

I hope this helped! :)

Answer:

assuming the three options are no solutions, one solution and all real numbers, i would say the final option. i forgot what the proper wording is thoough

The given expression will have no solution.

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given an expression, 9x - 18 = 3(3x - 6)

In the given expression, both LHS and RHS are equal, therefore it will have no solution.

Hence, The given expression will have no solution.
