Translate 4n=x(5-n) into a sentence

Answers

The product of 4 and  a certain number (n) equals the product of another number(x) and the difference between 5 and the number(n)

The given equation is:

4n  =  x(5  - n)

   Before we translate the whole equation into a sentence, we need to observe that there are two unknown numbers in this equation

The first number = n

The second number = x

4n  =  The product of the first number and 4

5 - n = The difference between 5 and the first number

x(5 - n) = The product of the second number and the difference between 5 and the first number

Combining all the sentence above, 4n = x(5 - n) translates to:

The product of 4 and  a certain number (n) equals the product of another number(x) and the difference between 5 and the number(n)

90 < x < 180 is my range and my answer is 0.6 for it to be correct is it positive or negative?

Answers

It doesn't matter. It can't be correct either way.

The range says that 'x' is a number between 90 and 180.

Neither -0.6 nor +0.6 is between 90 and 180.

do you mean like are the numbers positive or negative?

It is more than 90 and less than 180 so the two numbers could be 96 x 0.00625

Find the total travel time: Depart 5:30 pm MST Arrive 9:20 pm CST. United States
atz
3 hr 40 min
2 hr 50 min
1 hr 50 min
3 hr 50 min

Answers

Answer:

2 hour 50 minutes

Step-by-step explanation:

Given data: Departure = 5:30 pm MST, Arrive = 9:20 pm CST

Note that MST is the time zone 1 hour before CST.

Let us convert MST into CST.

Departure = 5:30 pm MST = 6:30 pm CST

Total time travel = Departure – Arrival

= 9.20 pm MST – 6.30 pm MST

= 2 hour 50 minutes

Hence, total time travel is 2 hour 50 minutes.
