1/3 ( x - 10) = -4 ???

Pepsi [2]

Answer:

$x = - 2$

Step-by-step explanation:

1) Simplify 1/3 ( x - 10) to x-10/3.

$\frac{x - 10}{3} = - 4$

2) Multiply both sides by 3.

$x - 10 = - 4 \times 3$

Simplify 4 × 3 to 12.

$x - 10 = - 12$

4) Add 10 to both sides.

$x = - 12 + 10$

5) Simplify -12 + 10 to -2.

$x = - 2$

So, therefor, the answer is, x = -2.

What is 6dm in a fraction

Verdich [7]

It all depends on what you are comparing it to... if you want what fraction of a meter it is...

There are 10 decimeters per 1 meter so 1 dm is 1/10 of a meter which means 6 dm = 6 × 1/10 = 6/10 = 3/5

6 dm = 3/5 m

Vedavit walks his dog the same distance each day. After 5 days, he has walked his dog 1 mile. How many feet does he walk his dog

posledela

Answer:

$1056 ft$

Step-by-step explanation:

''Vedavit walks his dog the same distance each day.''

After 5 days,he has walked his dog 1 mile.''

First we are going to convert the total distance (1 mi) to feet.

The relation is :

$1mi=5280 ft$

After 5 days, he has walked his dog 5280 ft.

The next step is to divide the total distance for the amount of day that he has walked his dog (we do this because Vedavit walks his dog the same distance each day)

$\frac{5280ft}{5 days} =1056\frac{ft}{day}$
