Which expression shows the distance on the number line between −7 and 16?

a) |−16−(−7)|

b) |−7+16|

c) |7−16|

d) |−7−16|

Answers

Final answer:

The correct expression to find the distance on the number line between -7 and 16 is |16 - (-7)|, which equals 23 units. The distance is always a positive number.

Explanation:

The expression that shows the distance on the number line between −7 and 16 is |16 - (-7)|.

To find the distance between two points on a number line, subtract one point from another and take the absolute value of the result. This ensures the distance is positive, as distance cannot be negative. Hence, the correct expression is:

|16 - (-7)| = |16 + 7| = |23| = 23

So, the distance between the points is 23 units.

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.

Answers

Final answer:

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.

the sum of two numbers is 55 and the difference is 9. what are the numbers?

Answers

x + y= 55
x - y= 9
y = 23
x = 32

the numbers are 23 and 32
Difference is 9: x-y=9
From the second equation x=9+y (substitute that into the first equation to solve for y).
9+y+y=55


2y=46

y=23. (Substitute that back into the second equation to find x.)
x=9+y = 23+9 = 32.
23+32 = 55 (Check).

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

Answers

Final answer:

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.

geometry homework please help

Answers

let's start with triangle UVT, in this triangle we have UV = VT, therefore, measure angle VUT is equal to measure angle VTU.
we also know that measure angle UVT = 20°
thus, angle VUT + angle VTU = 180-20=160°
since these two angles are equal, each of them will measure 160/2=80°

now, we have measure anglr RUT=90° and measure angle VUT=80°, therefore,

Find the equation of a line that is parallel to the line x= -14 and contains the point (-4,2)

Answers

Two lines that are parallel have the same slope.

The given line, x = -14, is a vertical one.  Its slope (rise/run) is undefined due to division by zero.  Any line parallel to x = -14 is also vertical.  Since the new line goes through (-4,2), the equation of the new line is x = -4.
Final answer:

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.

C = 5/8 (0.625)
D = 3/4 (.75)

the last option is your answer

A fraction is a way to describe a part of a whole. The correct option is D.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

To arrange the given fraction simply the given fraction as shown below.

3/4 = 0.75

1/4 = 0.25

7/16 = 0.4375

5/8 = 0.625

Since it can be seen that the points are arranged on the number line, therefore, the first point will have the least value, while the last point will have the maximum value.

Therefore, each point can be written in the fraction form as,

A = 0.25 = 1/4

B = 0.4375 = 7/16

C = 0.625 = 5/8

D = 0.75 = 3/4

Hence, A=1/4,B=7/16,C=5/8,D=3/4.
