The mathematical expression of 365.25 can be expressed in in expanded form as
A number can be expressed in expanded form as the sum of its digits' place values. In the expanded form, a number is divided into units based on the place values of the digits, then expanded to show the value of each unit. The division of numbers into groups according to place value, such as ones, tens, hundreds, thousands, ten thousand, and so forth, results in the expanded form of the number.
The given value can be expressed as;

Answer:
Step-by-step explanation:
When you have an inequality like this, you can treat it like an equation except for one part. If you ever divide or multiply it by a negative number or variable you have to flip the inequality. if it is equal to as well you keep that though. for instance
-5x ≤ 10
x ≥ -2
Anyway, in your case you have two inequalities, so you have to solve both and see what makes both true.
We'll start with 12x - 39 ≤ 9
12x - 39 ≤ 9 First add 39 to both sides
12x ≤ 48 Now divide both sides by 12, positive so no flipping
x ≤ 4
Next is:
-4x + 3 < -6 First subtract 3 from both sides
-4x < -9 Now divide both sides by -4, which means the sign flips
x > 9/4
Now, without even looking at the answers, what number or numbers are less than or equal to 4 and greater than 9/4? Well we pretty much described it there. All numbers starting from, though not including 9/4, which is 2.25, all the way up to, and including 4. B shows exactly that.
To solve the inequalities, the first is simplified to x > 4 and the second to x > 2.25 after applying proper arithmetic operations and considering the signs during division.
The student's question involves solving two inequalities, one of which is a linear inequality, and the other an inequality that requires adding or subtracting to isolate the variable. To solve the inequality 12x - 39 > 9, we add 39 to both sides to get 12x > 48, then divide both sides by 12 to find that x > 4. For the inequality -4x + 3 < -6, we subtract 3 from both sides to get -4x < -9, then divide by -4, remembering that dividing by a negative number reverses the inequality, resulting in x > 9/4 or x > 2.25.

Answer:
11.75 miles
Step-by-step explanation:
Note that each distance is found by adding 1.625 to the previous one:
5.25 + 1.625 = 6.875 (which is equal to 6 7/8);
6.875 + 1.625 = 8.5 (which is equal to 8 1/2)
On Wednesday Jaime will bike 8.5 + 1.625 miles, or 10.125 miles, and
on Friday he will bike 10.125 miles + 1.625 miles, or 11.75 miles
