The sum of 43.9 and a number is 49.65, as shown below. what number should go in the box to complete the addition problem? 43.9 plus box.75 equals 49.65

5

Step-by-step explanation:

The sum of 43.9 and a number is 49.65

First make equation using given phrase

Let number be x

"sum of 43.9 and a number" ⇒ 43.9 + x

43.9 + x  is 49.65

Therefore, 43.9 + x = 49.65

Now solve for x

43.9 + x = 49.65     [ subtract 43.9 both sides ]

          x = 49.65 - 43.9

          x = 5.75

Expression:  

43.9 + ?.75 = 49.65

          ↓

43.9 + 5.75 = 49.65

So, ? = 5

Hence, 5 will go in the box

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
