Can someone please help me on this and explain if you can!

Answer:

x = 381/24 = 3 29/84

Step-by-step explanation:

7x + 1/2(x + 1/4) = 3(6x - 9) - 8

Use the distributive property to multiply 1/2 by x + 1/4.

7x + 1/2x + 1/8 = 3(6x - 9) - 8

Combine 7x (14/2x) and 1/2x to get 15/2.

15/2x + 1/8 = 3(6x - 9) - 8

Use the distributive property to multiply 3 by 6x - 9.

15/2x + 1/8 = 18x - 27 - 8

Subtract 8 from -27 to get -35.

15/2x + 1/8 = 18x - 35

Subtract 18x from both sides.

-21/2x + 1/8 = -35

Subtract 1/8 from both sides.

-21/2x = -35 - 1/8

-35 is the same as -280/8.

-21/2x = (-280 - 1)/8

Subtract 1 from -280 to get -281.

-21/2x = -281/8

Multiply both sides by -2/21 (reciprocal of -21/2).

x = (-281 * -2)/(8 * 21)

You can cross cancel -2 and 8 by extracting 2 (they become -1 and 4 respectively).

x = (-281 * -1)/(4 * 21)

Multiply -281 by -1 to get 281.

x = 281/(4 * 21)

Multiply 4 by 21 to get 84.

x = 281/84

Can this fraction be simplified into a mixed number? Yes it can. It becomes 3 29/84. (252 (3 * 84) + 29 = 281)

x = 3 29/84

Work check: x is substituted for 281/84 (convenience)

7 * 281/84 + 1/2(281/84 + 1/4) = 3((6 * 281)/84 - 9) - 8

1967/84 + 1/2(281/84 + 1/4) = 3((6 * 281)/84 - 9) - 8

1967/84 + 1/2(302/84) = 3((6 * 281)/84 - 9) - 8

(1967 + 151)/84 = 3((6 * 281)/84 - 9) - 8

2118/84 = 3(1686/84 - 9) - 8

2118/84 = 3((1686 - 756)/84) - 8

2118/84 = 3(930/84) - 8

2118/84 = 2790/84 - 672/84

2118/84 = (2790 - 672)/84

2118/84 = 2118/84

So x = 3 29/84 is correct.

Answer:

El precio de la entrada al cine es de $56

Step-by-step explanation:

Cada uno de los 4 amigos las 2 veces por semana consumen un paquete de palomitas que cuesta: $28  ; entonces debemos multiplicar el costo de las palomitas por las dos veces que las consumen para saber el costo total de las palomitas:

                                                 28 x 2 =$56

El ejercicio nos dice que al no comer esas dos veces palomitas pueden ingresar a cine una tercera vez por semana ,lo que significa que al no pagar los $56 en palomitas podrán pagar una tercera entrada,lo que quiere decir que la entrada a cine es de $56.

Entonces podemos hacer la siguiente relación matemática: Precio total de las palomitas dos veces por semana = Precio de la entrada a cine.

Answer:

13,200 vehicles

Step-by-step explanation:

57% of 80,000 is 45,600

3 people per car for 2000 vehicles is 6,000

45,600-6,000=39,600

lastly 39,600/3=13,200

Step-by-step explanation:

for exampe 9+8=17 can be rewritten as 17-9=8

Answer:

See explanation below

Step-by-step explanation:

Find the value of x in each of the following

1) x-1+5√x-1+3=0

5√x-1 = -x -2

Square both sides

25(x-1) = (-x-2)^2

25(x-1) = x^2+4x + 4

25x-25 = x^2+4x + 4

x^2 +4x + 4 - 25x + 25 = 0

x^2 - 21x + 29 = 0

x = 21±√21²-4(29)/2

x = 21±√441-116/2

x = 21±√325/2

x = 21±18.03/2

x = 21+18.03/2 and 21-18.03/2

x = 19.515 and 1.485

4)  x^4-64=0

x^4 = 64

[tex]x = \sqrt[4]{64}[/tex]

x = 2.83

Answer:

Fairview is lower.

Step-by-step explanation:

IXL

The required, city Fairview has a lower ratio of negative to positive reviews.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

here,
A restaurant critic reviewed restaurants in Oxford and Fairview.
In Oxford, the critic gave 18 negative reviews and 33 positive reviews.
ratio = 18 / 33 = 0.54

In Fairview, 5 of the reviews were negative and 11 were positive reviews.
Ratio = 5 / 11 = 0.45

Thus, the required, the city of Fairview has a lower ratio of negative to positive reviews.

Answer:

Approximately 40.37 feet

Step-by-step explanation:

Opposite = 30 feet and the length of the wire (I'll use x to represent it) is the hypotenuse.

sin(48) = 30/x

x = 30/sin(48)

x = 30/0.74

x ≈ 40.37

Answer:

an = 6n - 18

Step-by-step explanation:

a3 = 0, a4 = 6, a5 = 12, a6 = 18, a7 = 24

a3 = a + 2d

a4 = a + 3d

a + 2d = 0 (1)

a + 3d = 6 (2)

Subtract (1) from (2) to eliminate a

3d - 2d = 6 - 0

d = 6

Substitute d = 6 into (1)

a + 2d = 0 (1)

a + 2(6) = 0

a + 12 = 0

a = -12

nth term,an = a + (n - 1)d

= -12 + (n - 1) 6

= -12 + 6n - 6

= 6n - 18

an = 6n - 18

5^2-3^2=16

sqrt16=4

Answer:

A. 4

Step-by-step explanation:

hypotenuse (h) = 5

base (b) = 3

perpendicular (p) = a = ?

We know

By using Pythagoras theorem

p = √( h² - b²)

a = √( 5² - 3²)

a = √(25 - 9)

a = √ 16

a = 4
