Answer:

Karson's average speed on his way home was 28 miles per hour.

Step-by-step explanation:

Since Karson drove from his house to work at an average speed of 35 miles per hour, and the drive took him 20 minutes, if the drive took him 25 minutes and he used the same route in reverse, to determine what was his average speed going home, the following calculation must be performed:

60 = 35

20 = X

20 x 35/60 = X

700/60 = X

11.666 = X

25 = 11,666

60 = X

60 x 11.666 / 25 = X

27.99 = X

Therefore, Karson's average speed on his way home was 28 miles per hour.

Answer:

x = 10

Step-by-step explanation:

3x - 9 = 21

add 9 on both sides:

⇒ 3x - 9 + 9 = 21 + 9

⇒ 3x = 30

divide 3 on both sides:

⇒ \frac{3x}{x} = \frac{30}{3}

⇒ x = 10

to check answer, substitute x by 10 on the original equation:

⇒ 3x - 9 = 21

⇒ 3 x 10 - 9 = 21

⇒30 - 9 = 21

⇒ 21 = 21

The volume of a rectangular prism is given by the formula V = lwh, where l is the length of the prism, w is the width, and h is
katen-ka-za [31]
The expression that represents the volume would be: <span>C) 6x^3+39x^2+54x</span>

Proof of the calculation:

V = Lwh

V = (x+2) (3x)  (2x+9)

V= (3x^2 + 6x) (2x + 9)

V = (6x^3 + 27X^2 +12x^2 + 54x)

V = 6x^3 + 39x^2 + 54x
