What is the equation of the line –3x–2y=30 in slope-intercept form?

Answers

Answer

y = (-3/2)x - 15

Explanation

The general linear equal in slope intercept form is y = mx + c.

Where m is the slope and c is the y-intercept.

–3x–2y=30 in slope-intercept form

–3x–2y=30

-2y = 3x + 30

y = (-3/2)x - 15

Answer:

$y = (-3)/(2)x - 15$

Step-by-step explanation:

We are given the following information in the question:

We are given equation of line:

$-3x-2y = 30$

The slope intercept form of a straight line is given by:

$y = mx +c$

where m is the slope of the line and c is the y intercept of the line.

Considering the given equation of the line:

$-3x-2y = 30\n-2y = 3x + 30\ny = \displaystyle(3x + 30)/(-2)\n\ny = (-3)/(2)x - 15$

is the required form of line.

where the slope of the given line is m = $(-3)/(2)$ and y-intercept is c = -15

Rayville Elementary sponsors a math competition for 78 students. During the competition, the students work a total of 8,970 math problems in 4 hours. Each student works the same number of problems. How many problems does each student work?

Answers

Each student worked on 115 math problems.

Step-by-step explanation:

Given,

Problems solved in 4 hours = 8970

Number of students in competition = 78

As each student solved same number of problems, we will divide the total problems solved by number of students to find the amount of problems solved by one student.

Problems solved by one student = $(8970)/(78)$

Problems solved by one student = 115

Each student worked on 115 math problems.

Explanation:

I'm going to copy and paste the question here, and bold important info.

"Rayville Elementary sponsors a math competition for 78 students. During the competition, the students work a total of 8,970 math problems in 4 hours. Each student works the same number of problems. How many problems does each student work?"

Now everything not bolded? Forget about it. All you need to know is that there are 78 students. They all do 8,970 # of problems. And all the students do the same amount. Now you just have to divide the # of probs. by the amount of students in the competition, and you have your answer.

8970÷78=115

Hope that helped!

Janet solves 6 questions from a math assignment.If this is 30% of questions given in the assignment, what is the total number of questions given in the assignment?

Answers

30% of his questions was 6 questions.
Translate that to a math equation where q= total number of questions.
30% x q = 6
.3 x q = 6
q= 6/.3
q= 20

There were 20 questions in the test.
And 30% of 20 is 6 so that is the correct answer.

Hope this helps :)

6 out of x questions are answered.

Lets set up a proportion:

6/x = 30/100
100 here acts as the whole number that we currently don't know of.

6*100 = 600
30x = 600
x = 20

There are 20 total questions on the test in this case.
