1/3n<-9

Answers

Answer:

" all numbers less than -27 "

Step-by-step explanation:

The instructions for this problem most likely go like this:  "solve the following identity."  In other words, find an inequality for n.

Start by multiplying both sides of the given inequality by 3, to eliminate the fraction 1/3:

n < -27

The solution:  " all numbers less than -27 "

All numbers are less of -27 so the person that answered before me is correct

-8(1+4x)+7x=-25-8x

Answers

Answer:

x = 1

Step-by-step explanation:

-8(1+4x)+7x=-25-8x (Given)

-8 + -32x + 7x = -25 - 8x (Distribute)\

-8 + -25x = -25 - 8x (Combine like terms)

-17x = -17 (Move variables(x) to the left and constants to the right)

x = 1 (Divide) (the answer is positive because when you divide a negative number by a negative number it turns positive)

X=1 Same explanation of the first Who answered the problem

Evaluate the expression when b=9 and c=4 . bc+12.3 =

Answers

48.3

9*4 = bc, equals 36
36+12.3, equals 48.3
48.3 because when two letters are next to each other and they are worth a number you multiply them for example 9(4)+12.3 so first you multiply 9 and 4 you should get 36 then you add 12.3 which will get you 48.3

Miss Riley's class has 24 students. She has the students in groups. Each group can have no more than 5 students. if every student has to be in groups how many does she have left?

Answers

Answer:

if there can be no more than 5 students, then anything less than 5 students will suffice. However we don’t want any left over ones cause we don’t want that one kid sitting alone during lunch so we can simply put 4 into each group.

Step-by-step explanation:

Hope this helped :DDD

Answer:

6 groups, 4 students in each one

Step-by-step explanation:

The factors of 24 include 6 and 4

That means that you can break 24 into those numbers

You are able to put the students up into groups of 6, with 4 students in each

However, you cannot place the students into groups of 4 (with 6 students in each) because no more than 5 students are allowed in each group

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . If a customer paid 120 dollars , how many international minutes did they use ?

Answers

Answer: The answer would be 950 international minutes. Only if assuming that this is in one month since the question doesn't give much detail.

Step-by-step explanation:

X would be used to represent the number of months.

25+0.10x=120

0.10x=95

950 international minutes used

Answer:

950

Step-by-step explanation:

An equation to model this scenario would be: y = 0.1x + 25

y would mean the amount of money paid depending on x, which is the number of minutes.

In this problem, we know the amount of money. So we know y is 120.

We can then put 120 into the equation to find x.

120 = 0.1x +25  

95 = 0.1x

x = 950

Therefore, x is 950.

Answers

Answer:

Stem and Leaf Plot ⇒ Makes it easy to see the largest, smallest and most common data values.

Double Bar Graph ⇒ Compares two sets of data.

Bar Graph ⇒ Shows whether one type of data increases, decreases or neither when another type of data increases.

Scatter Plot ⇒ Shows the frequency of results and trends clearly.

Step-by-step explanation:

Stem and Leaf Plot makes a set of data easy to see and shows common data values together.

Double bar graph is the only graph that focuses solely on 2 sets of data.

Bar Graph description is a bit weird for this one to me but it's the last one (I did others first) and it is close enough.

Scatter plot is best at showing frequency and trends and to see the approximate increase/decrease of many data points.

WILL MARK BRAINLIEST PLS HELP. Fill in the table by following the rules provided for each backpack.

Answers

Answer:

See complete answer

Step-by-step explanation:

Backpack 2 is 2x, 2y, so double each number:

(0,2) = (0, 4)

(8,2) = (16, 4)

(6,5) = (12, 10)

(2,5) = (4, 10)

(0,2) = (0,4)

Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:

(0,2) = (8, 0)

(8,2) = (16, 0)

(6,5) = (14, 3)

(2,5) = (10, 3)

(0,2) = (8, 0)

Backpack 4 is x, 2y, so keep the same x and multiply y * 2

(0,2) = (0, 4)

(8,2) = (8, 4)

(6,5) = (6, 10)

(2,5) = (2, 10)

(0,2) = (0,4)

Answer. 68%
Explanation: divide 17 by 25 and you will get .68 which you convert to a percent

Answer:

68%

Step-by-step explanation:

     Here, it asks for the percentage that attended, and percentage is a ratio expressed as a fraction of 100. First, we must start with the total number of students, not to be confused with the total number of students who attended. The total number of students in the class is 25, which we must multiply to get to a hundred.

     This depends on the number of course. For example, if the number were to be greater than 100, then you would divide, but never adding or subtracting, but in this case, we must stick with multiplying as 25 is less than 100. As you should know, 24 times 4 equals hundred, so you must multiply 17 by 4 too in order for it to be equal, which leaves you with 68/100 attending the part, meaning the percentage of students attending the dance is 68%.
