861 ÷3 show work for this problem please
TEA [102]
861 divided by 3: 

How many times does 3 go into 8? 2 x 3 = 6 
Subtract 6 from 8 to get a remainder of 2, and bring down 6 to get 26. 

How many times does 3 go into 26? 8 x 3 = 24
Subtract 24 from 26 to get a remainder of 2, and bring down 1 to get 21. 

How many times does 3 go into 21? EXACTLY 7 times. 7 x 3 = 21

Collect all numbers in bold to get…. 287!

Therefore, 861 divided by 3 = 287.

The length of a rectangle is 3 cm less than twice the width. If the perimeter is 42 cm, what is the length of the rectangle?
larisa [96]

Answer:

The length is 13

Step-by-step explanation:

w+w+l+l= perimeter

if the length is 3m less than twice the width then let's do some math.

42 divided 2 =21. so the width and length of one side have to equal 21. For example, let's use 8 as the width. The length would be twice(16) minus three(13) 13 plus 8 is 21. WOW it equals half of it so no we know the length is 13 and the wdith is 8.
