Answer:

E)  1004.8 cm^{3}

Step-by-step explanation:

Volume of a cylinder, V = πr^{2}h

Radius, r = 8 cm

Height, h = 5 cm

π = 3.14

Substitute the values of r and h

V = 3.14 * 8^2 * 5

V = 3.14 * 64 * 5

V = 1004.8 cm^{3}

14x + 6 = 5x - 3 with solution
Schach [20]

hey there

the answer is

14x + 6 = 5x + -3


6 + 14x = 5x + -5

6 + 14x = -3 + 5x


6 + 14x + -5x = -3 + 5x + -5x


Combine like terms: 14x + -5x = 9x

6 + 9x = -3 + 5x + -5x


Combine like terms: 5x + -5x = 0

6 + 9x = -3 + 0

6 + 9x = -3

6 + -6 + 9x = -3 + -6


Combine like terms: 6 + -6 = 0

0 + 9x = -3 + -6

9x = -3 + -6


Combine like terms: -3 + -6 = -9

9x = -9


Divide each side by '9'.

x = -1


Simplifying

x = -1

thank you

Se sabe q la suma de tres numeros es de 850. El primer es un tercio del segundo y el tercer número es el doble del segundo.¿Cual
murzikaleks [220]

Answer:

Primer número = x = 85

Segundo número = y = 255

Tercer número = z = 510

Step-by-step explanation:

Se sabe que la suma de tres números es 850. El primero es un tercio del segundo y el tercer número es el doble del segundo.

Representamos:

Primer número = x

Segundo número = y

Tercer número = z

Se sabe que la suma de tres números es 850.

x + y + z = 850 ...... Ecuación 1

El primero es un tercio del segundo

x = 1/3 años

El tercer número es el doble del segundo.

z = 2 años

Sustituimos 1 / 3y por x y 2y por z en la Ecuación 1

1 / 3y + y + 2y = 850

y / 3 + 3y = 850

Multiplica ambos lados por 3

y + 9y = 850 × 3

10 años = 2550

y = 2550/10

y = 255

Resolviendo para x

x = 1/3 años

x = 1/3 × 255

x = 85

z = 2 años

z = 2 × 255

z = 510

Por eso,

Primer número = x = 85

Segundo número = y = 255

Tercer número = z = 510

3) David goes into a candy store with $5.00. He buys 9 peppermints for $0.15
yuradex [85]
<h3>Write an equation that will match the story problem​</h3>

x=(5 - (9 \times 0.15) ) \div 0.25

<em><u>Solution:</u></em>

Given that,

David goes into a candy store with $5.00

Total amount with David = $ 5

He buys 9 peppermints for $0.15 each

And some sour candies. each sour candy costs $0.25

The equation is:

Let the number of sour candies bought be "x"

Then,

Remaining amount after buying pepper mint = 5 - 9 \times 0.15  = 3.65

Each sour candy cost $0.25

<em><u>Now the number of sour candies bought is:</u></em>

3.65 = 0.25 \times x

x = 14.6

Thus david can buy 14 sour candies

<em><u>Thus the equation that will match the story problem​ is:</u></em>

x=(5 - (9 \times 0.15) ) \div 0.25

Where, "x" means number of sour candies bought
