Answer:
infinite Solutions
Step-by-step explanation:
12x+1 = 12x+3-2
12+1 = 12x+1
The equation is same on both sides, so x can be anything.
Solving for variables in equations is important for many reasons. Of course, it's important to be able to solve for them so you can pass math tests. But even more so, it's important for real-life applications. There are many uses for solving equations. They can provide answers for mathematicians, accountants, insurance companies- you name it! There are way too many to list! It may not seem important now, but just keep working at it! I personally think solving equations is a ton of fun!
4/29 is the probability that a student who did not complete the homework passed the test.
<u>Step-by-step explanation:</u>
It is given that,
There are 29 students in a math class.
Two types of students who passed the test and are not passed the test.
The other two types of students are who completed the assignment and did not complete the assignment.
So, the given data can be formed as a table.
- There were 22 students who passed the test.
- There were 20 students who completed the assignment.
- There were 18 students who passed the test and also completed the assignment.
Passed the test Not passed the test Total
Completed assignment 18 - 20
Not completed assignment x - -
Total 22 - 29
Now, you need to find the probability that a student who did not complete the homework passed the test.
⇒ No.of students completed assignment passed the test / Total students.
<u>To find the no.of students completed assignment passed the test :</u>
Let 'x' is the no.of students completed assignment passed the test.
⇒ 18+x = 22
⇒ x = 22 - 18
⇒ x = 4
∴ P(students completed assignment passed the test) = 4 / 29.
Answer:
Step-by-step explanation:
The given expresion is:
We want to find the first step in simplifying the above expression based on order of operations.
We use PEDMAS, so we deal with parenthesis first.
Within the parenthesis, we still need to multiply first to get:
