I am an odd number, I am less than 100, the sum of my digits is 12, I am a multiple of 15. What number am I
The number is 75, which satisfies all given conditions: it is an odd number, less than 100, a multiple of 15, and the sum of its digits is 12.
Explanation:To find an odd number that is a multiple of 15, less than 100, and has a sum of digits that equals 12, we must first consider that multiples of 15 end with a 5 or 0. Since the number is odd, it must end with a 5. Additionally, the number must be less than 100, so we are looking for a two-digit number.
We know the sum of the digits is 12, and since the last digit is 5, the first digit must be 7 to reach a sum of 12 (7+5=12). This means the number we are looking for is 75, which is indeed a multiple of 15, less than 100, has a sum of digits equal to 12, and is an odd number.

Joseph is not correct.
What is place value?- Any number formed from some digits, each digit has a place value.
- For example : 1,234 this number formed from 4 digits
The place value of 4 is ones ⇒ 5
The place value of 3 is tens ⇒ 40
The place value of 2 is hundreds ⇒ 300
The place value of 1 is thousands ⇒ 2,000
1,234= 1,000 + 200 + 30 + 4
Now the given number is 9,999,999
Now the place value of each digit is given as,
∵ The number formed from 7 digits
- The place value of the leftmost digit is millions
- The place value of the digit before the million is hundred thousands
- The place value of the digit before the hundred thousands is
ten thousands
- The place value of the digit before the ten thousands is thousands
- The place value of the digit before thousands is hundreds
- The place value of the digit before hundreds is tens
- The place value of the digit before tens is ones
∴ 9,999,999 = 9,000,000 + 900,000 + 90,000 + 9,000 + 900
+ 90 + 9
∴ Each digit from the leftmost digit is ten times the digit before it
Hence, Joseph is not correct.

The distance between bills house and his aunts house is 485 miles about how many miles would bill drive if he made 4 round trips from his house to his aunts house
Answer:
3880 miles
Step-by-step explanation:
Distance between Bill's house and his Aunt house = 485 miles
Distance traveled in one round trip = two times the distance between the Bill's house and his Aunt house
Distance traveled in one round trip = 2 x 485 = 970 miles
So, the distance traveled in 4 round trip = 4 x 970 = 3880 miles.
Thus, the distance traveled by teh bill in 4 round trips is 3880 miles.

Describe the solutions of 4 + n > −2 in words.
The value of n is a number less than −6.
The value of n is a number greater than or equal to −7.
The value of n is a number equal to −7.
The value of n is a number greater than −6.
The solution to the inequality 4 + n > -2 is n > -6. This means the value of n can be any number that is greater than -6.
Explanation:The inequality 4 + n > -2 can be solved to find the solution for 'n.' Start by subtracting 4 from each side of the inequality to isolate 'n.'
Here's the step-by-step calculation: 4 + n > -2 becomes n > -6 when we subtract 4 from both sides.
So, the value of n is any number that is greater than -6. In other words, n can be just a little bit more than -6, -6.01 for example, or it can be a much larger number, like 1, 100, or 1000, etc.

what is to 20 ≥ 4/5w
The inequality 20 ≥ (4/5)w represents a comparison between a number and a variable multiplied by a fraction. To solve it, you isolate the variable. The solution is w <=25.
Explanation:The inequality 20 ≥ (4/5)w represents a mathematical statement comparing a number, 20, with a variable, w, multiplied by a fraction, 4/5. The inequality sign, ≥, indicates that 20 is greater than or equal to the result of the multiplication. To solve this inequality, you need to isolate the variable on one side of the inequality sign.
To get rid of the fraction, multiply both sides of the inequality by the reciprocal of 4/5 which is 5/4. This gives you (5/4) * 20 ≥ (5/4) * (4/5)w which simplifies to 25 ≥ w.
Therefore, the solution to the inequality is w <=25.

Find the equation of a line that is parallel to the line x= -14 and contains the point (-4,2)
The equation of the line that is parallel to x = -14 and passes through the point (-4, 2) is x = -4.
Explanation:The line x = -14 is a vertical line. Any other line parallel to it would also be a vertical line. The equation of a vertical line in the 2-dimensional coordinate space takes the form x = k, where k is a constant. To find the equation of a line that is parallel to x = -14 and passes through the point (-4, 2), we just need to substitute the x-coordinate of the point into the equation, resulting in x = -4.
