aniked [119]

The total distance of the route is 112miles.

Step-by-step explanation:

Let us consider the total distance of the route to be 'y'.

Given that,

The distance from Boston to the passengers station = (1/3) y

The passenger got down at a station after beyond his station which is 14 miles away and the remaining route from that station is (13/24) y

So the travelled route = y - (13/24) y

= (11/24) y

The travelled route is from Boston to a station beyond 14miles of his station.

We can write the above as,

(11/24) y = (1/3) y + 14

(11/24) y - (1/3) y =14

(11y - 8y) /24 = 14

3y/24 = 14

y/8 = 14

y = 14 x 8

y = 112 miles

The total distance of the route is 112 miles

What is the total cost of one dozen pens if each pen costs 0.29
LUCKY_DIMON [66]
The total cost would be $3 dollars and 48 cents because one dozen is equal to 12. Just multiply 0.29 by 12 to get $3.48.

The simplified forms of the given expressions are

a. 32x

b. 0

c. -26t + 14x

d. 3t

<h3>Simplifying an expression </h3>

From the question, we are to simplify the given expressions by adding or subtracting

a. (10x) + (22x)

= 32x

b. (-6x) - (-6x)

= -6x + 6x

= 0

c. (-13t) + (14x) - (+13t)

= -13t + 14x - 13t

Collect like terms

= -13t -13t + 14x

= -26t + 14x

d. (-4t) + (+4t) - (-3t)

= -4t + 4t + 3t

= 3t

Hence, the simplified forms of the given expressions are

a. 32x

b. 0

c. -26t + 14x

d. 3t

Which sets are not closed under subtraction
anastassius [24]

If you're referring to the different sets of real numbers, it's the ones that you could try to do subtraction and not get an answer that still in that set.

For example, natural numbers (aka 1, 2, 3, 4, ...) are not, because 7 - 11 = -4 and -4 is not a natural number.

Also, whole numbers (aka 0, 1, 2, 3, 4, ...) has the same issue.

Basically any set of real numbers that doesn't include negative numbers will have this issue.
