Answers

Answer 1

Answer:

Answer: Yes it is true. We can write an equation by setting an expression equal to itself.

Step-by-step explanation:

Let we take an expression say 2x.

Since we know that any expression is equal to itself, so we can write it as 2x=2x, which does not give any solution or we can say this equation has no solution but we can not say it is false because they are actually equal.

Therefore, we can write an equation by setting an expression equal to itself. It would be a true equattion.

Answer 2

Answer: Yes it would.
An equation says two things are equal.
So if you have an expression x + 1 and you set it equal to x + 1
you have x + 1 = x + 1, which is a true and valid equation, not saying it's any useful but it is an equation.

Answers

the mode (number that occurs most often) = 393 since it appears twice in this sequence

the mean (all the numbers added together and divided by the number of numbers in the sequence)= 393 +393 + 400 + 482 + 496 +507 +509 + 511= 3691

the median (when, the numbers are placed in order from lowest to highest, the middle number, or if there is a even amount of numbers, the two middle numbers added together than divided by 2) = 482 + 491 = 973/2 = 486.5

these three terms are all different forms of the average, although once you get to high school you will learn that they may not be very accurate when there is outliers, to which you will learn how to calculate the outliers and how to descaled them form your calculations :)

Plz helpWhat is sum of 5.3x10^5 and 3.8x10^4

A. 4.33x10^4
B. 5.68x10^5
C. 9.1x10^9
D. 9.1x10^5

Answers

This is a classic example of Scientific Notation.
5.3 x 10^5 actually equals 530,000
3.8 x 10^4 actually equals 38,000
Since it is asking for the sum of the numbers you are adding.
Your new equation look like this:
530,000 + 38,000
= 568,000
now all you have to do is count the decimal points. You start from the end zero and count the spaces in between until you get to the tenths place. (Right behind the first number) There are 5
So your answer will be:
B. 5.68 x 10^5.

A.

earnings=bonus+pay
pay=pay per hour times number of hours
h=number of hours
9.5=pay per hour
pay=9.5h
bonus=60

earnings=9.5h+60
at least 460
greater than or equal to 460
9.5h+60>460

B. solve for h
9.5h+60>460
subtract 60
9.5h>400
divide oth sides by 9.5
h>42.1
at least 42.1 hour (about 42 hours and 6 minutes, if the job is rounding, then say 43 hours)

A. 9.5h+60>460
B. 42.1 hours

Each row of the grocery parking lot has 10 parking spots of equal width. What is the width for each spot? Combined with of the grocery store is 31.92.

Answers

Answer:

The answer is 3.192 width each spot.

Step-by-step explanation:

You have this information:

The total width of the grocery is 31.92.
10 parking spots of equal width.

If you assume that the width of these 10 parking spots is the same width of the total width of the grocery, then you have:

10x=31.92

//divide by 10 both sides of the equation

10x/10 = 31.92/10

x = 3.192

Well if you mean that the total width of all the parking spots is 31.92 then you would just divide that by 10 to get 3.192 but if you mean that it's 31.92 with the grocery store too then you need to know how wide the grocery store is too.
