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.
complete question:
Solve the inequality that represents the story. Then interpret what the solution means in the story.
Lin buys a candle that is 9 inches tall and burns down x inches per minute. She wants to let the candle burn for 7 minutes until it is less than 6 inches tall.
9 - 7x < 6
Answer:
x > 3/7
x which is the inches per minute the candle will burn should be greater than 3/7 for the candle to be less than 6 inches tall.
Step-by-step explanation:
The candle is 9 inches and it burns down x inches per minute. Lin wants to let the candle burn for 7 minutes until it is less than 6 inches tall. The inequality can be solved below.
9 - 7x < 6
subtract 9 from both sides of the equation
9 - 9 - 7x < 6 - 9
- 7x < - 3
divide both sides by -7
- 7x / -7 < - 3/ - 7
dividing both sides with a negative values changes the inequality sign
x > 3/7
x which is the inches per minute the candle will burn should be greater than 3/7 for the candle to be less than 6 inches tall.
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
<em>In the right triangle ABC</em>
-----> by a 45°-90°-45° triangle
so
substitute the values
<em>In the right triangle BCD</em>
substitute the values
The answer is x=8 because 8 goes into 24 three times
