Answer:

419

Step-by-step explanation:

Regrouping in subtraction: If we borrow from one group (tens group) and give to another (Once group) so that the operation can be completed, then this process is called regroup.

For example: We need to find the value of 52-39

52=50+2

39=30+9

We can not subtract 9 from 2. So we will borrow 10 from 50 and give to 2.

52=40+12

Now,

52-39=(40+12)-(30+9)

52-39=(40-30)+(12-9)

52-39=(10)+(3)

52-39=13

We need to find the greatest 3 digit number that can subtract from 426 so that we need to regroup.

To use regroup, the once digit must be more that 6. So, maximum value for once place is 9.

Therefore, the greatest 3 digit number that can subtract from 426 by using regroup is 419.

bixtya [17]
For this case, the first thing we must do is define a variable.
 We have then:
 x: number of gift boxes.
 We then have to write the inequation that models the problem:
 "Mary bought more than 72 pencils"
 "she packs 4 pencils each into x gift boxes"
 We have then:
 4x \geq 72
 Simplifying we have:
 x \geq 72/4
 x \geq 18
 Answer:
 
the inequality that represents this situation is:
 4x \geq 72
 The simplified form of the inequality is:
 
x  \geq 18

Allie rode her bike up a hill at an average speed of 12 feet/second. She then rode back down the hill at an average speed of 60
Volgvan

Answer:

The total distance Allie traveled was 0.81 miles.

Step-by-step explanation:

Since Allie rode her bike up a hill at an average speed of 12 feet / second, and she then rode back down the hill at an average speed of 60 feet / second, and the entire trip took her 2 minutes, to determine what is the total distance she traveled, the following calculation must be performed:

12 + 60 = 72

72 x 60 = 4320

1000 feet = 0.189394 miles

4320 feet = 0.8181818 miles

Therefore, the total distance Allie traveled was 0.81 miles.
