Write 24:14:6 in its simplest form.​
Iteru [2.4K]

Answer:

12 : 7 : 3

Step-by-step explanation:

24 : 14 : 6

12 : 7 : 3

Always start with smaller number to simplify it. Since 2 is the smaller number and it simplifies 24, 14, and 6 I start with it.

24 ÷ 2 = 12

14 ÷ 2 = 7

6 ÷ 2 = 3

We would stop here since it would not further simplify, therefore our answer is 12 : 7 : 3.

Hope this helps, thank you :) !!

Given the numbers c = –3 and d = 4, which statement is true? A. |–c| = 3 and |–d| = –4 B. |–c| = 3 and –|d| = –4 C. –|c| = –4 an
kirill [66]

<u>Answer:</u>

D. |–c| = 3 and –|d| = 4

<u>Step-by-step explanation:</u>

We are given these values of two variables and asked which of the statements in the given options is true:

c = –3 and d = 4

In mathematics, we know that the absolute value or modulus of a real number x is the non-negative value of x despite of whatever sign it has, positive or negative.

Therefore, the modulus of c  |–c| = 3 and modulus of  –|d| = 4 so option D is the correct one.

Jane took a train traveling at an average speed of 60 mph from Boston, MA to Washington, D.C. The trip took 8 hours. On her way
Trava [24]

Answer:

6.4 minutes

Step-by-step explanation:

The question gave us the following details:

Average speed = 60mph

Time spent on trip = 8 hours

Average speed of express train on way back = 75mph

T = distance/speed

D = distance

V = speed

T = d/v

d = v(t)

d = 60 x 8

= 480

Such that

480/75

= 6.4 hours.

That is 6 hours 40 minutes is the length of time it would take on the trip home.

Thank you!
