A. 15x+1.25=20
B. 1.25x+15=20
C. 1.25x-15=20
D. 15x-1.25=20
Changing the coefficient of x to 6 changes the meaning of expression as 5 is added to 6 times x
Solution:
Given that number 2 in the expression 5 + 2x is called the coefficient of x
We are asked to find what happens when changing the coefficient to 6 change the meaning of the expression
In the expression,
5 + 2x
This means 5 is added to 2 times x or 5 is added to twice of x
Number 2 is called coefficient of x
When we change this coefficient to 6, the expression becomes,
5 + 6x
So now the meaning of expression becomes,
5 is added to 6 times x
So changing the coefficient of x changes the meaning of expression
Answer:
The total value would increase.
Step-by-step explanation:
No matter what x is, as long as it is not zero, the value will increase, as 6 > 2, so 6, no matter what it is multiplied by, will end up greater than 2 multiplied by the same number.
Answer:
p = 12
Step-by-step explanation:
add 2 to both sides of the equation
24 = 2p ( divide both sides by 2 )
p = 12
Answer: p=2
Step-by-step explanation:
22=2p-2
You add two to 22 which will give you 24
24=2p
You want to divide the 2 to get the letter by itself
12=2
B) The first 100 students from an alphabetical list of sixth graders
C) One hundred random students from the entire school
D) One hundred random students from the sixth grade
One hundred randomstudents from the sixth grade. Therefore, option D is the correct answer.
In statistics, a simple random sample is a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way.
First off, the survey should be focused on the sixth graders, since they are the demographic that will be voting for 6th grade treasurer.
Next, the group should be random, because random groups better represent the entire class than an alphabetic list. Maybe those first 100 kids in the list like Noah because he has a last name that begins with A or something. It's not likely, but it's something that could corrupt the data collection.
Therefore, option D is the correct answer.

Answer:
Handling Money
Step-by-step explanation:
Fractions are of the form , where a and b are integers with b≠0. They, represents some part of the whole number.
Decimals are those fractions in which the denominators are powers of ten and numerators are the figures placed to the around the decimal point.
For e.g. 7.8 =
Now, there are many situations where using decimals are effective than using fractions.
For e.g. While handling money, decimals prove fruitful than fractions.
That is $2.45 is much easier to work with than $ i.e. $.
