-6m - 1 = -31

m = ___

please show work

Answers

ANSWER:

M = 5

Step 1: Add 1 to both sides of the equal sign

-6m-1+1=31+1

-6m=-30

Step 2: Divide both sides by -6

-6m/6 = -30/-6

(Note: Both -6 values (The denominators) will cancel each other out, which is why the end result is 5 so, again, M=5)

simplify: -7 - 8

Mini muffins are also sold at Muffin Mart. Each mini muffin is sold for $0.35. Diego has $3.00 for mini muffins. How many mini muffins can he buy with $3.00? *

Answers

Answer:

I agree with both.

Step-by-step explanation:

If it's $3 per dozen that would be $0.25 per muffin because

3÷ 12 = 0.25

And if Andre has $2 than he can only afford 8 muffins because

0.25 x 8 = 2

And if Elena wants 16 muffins

16 x 0.25 = 4

So she will have to pay $4.

Hope this makes sense and helps!

They will rest after they hike `2` miles. Then they will hike the remaining `1.75` miles to the lookout. The trail the hikers will use to return from the lookout is `0.5` miles shorter than the trail they will use to go to the lookout. Each hiker will bring `0.25` gallons of water for each mile to and from the lookout. What is the total amount of water each hiker will need to carry?

Answers

Answer:

1.75 gallons

Step-by-step explanation:

First, we need to calculate how far the hike is going up the trail. They first hike 2 miles and then another 1.75 miles after resting so...

2 + 1.75 = 3.75 miles

The trail is 3.75 miles long, the question states that the return path is 0.5 miles shorter, therefore...

3.75 - 0.5 = 3.25 miles

Leaving us with a total hiking distance of

3.75 + 3.25 = 7 miles.

Since each hiker will carry 0.25 gallons for each mile we simply need to multiply this amount by the total number of miles in the hike.

7 * 0.25 = 1.75 gallons

Finally, we can see that each hiker will carry a total of 1.75 gallons of water for the entire hike.

in order to do this, we would use order of operations. First, Parentheses, which is division with fractions, so we would do KCF,keep it, change it, flip it. keep the first fraction, change the operation to multiplication, then flip the next fraction, making it -7/9 x 3/1. the answer would be -2.33. multiply that by -2, and you would get -4.66, which is your answer.

What is the equation of the line that passes through the point (4,−7) and has a slope of -1/2?

Answers

Step-by-step explanation:

y = -0.5x + c

When x = 4, y = -7.

=> (-7) = -0.5(4) + c, c = -5.

Therefore the equation is y = -0.5x - 5.

Answer:

y = -1/2 x - 5

Step-by-step explanation:

y = mx + b

m = slope = -1/2

y = -1/2 x + b

-7 = -1/2 * 4 + b

-7 = -2 + b

b = -5

y = -1/2 x - 5

Is 72,681 is rounded to the nearest thousands

Answers

Answer:

70,000

Step-by-step explanation:

Answer:

The correct answer is 73,000.

Step-by-step explanation:

This is because, we know that the number 7 or 70,000 represents the ten-thousands in this number. Therefore, the number 2 or 2,000 represents the thousands place, which is what we are trying to round.

In order to do so, we have to look at the number behind it, which, in this case, is 6.

Rule: If the number is 4 or less, the number before it stays the same. If the number is 5 or more, the number before it goes up 1.

Since 6 is larger than 5, the 2 will become a 3, while the other numbers become 0s.

Therefore, the correct answer is 73,000.

Hope this helps! :)

The format of the message is sent as a string with information about the number of characters in the device ID, the device ID itself, the number of characters in the text message and the text message that is being sent with each part being separated by a space. The system uses this information to send the message to the correct device and the receiving device displays only the text message. The number of words in the text message is also useful. A word is defined by strings separated by spaces.Here is a sample VALID message:04 1234 05 helloThe first two digits in the string represent the length of the device ID to follow.The device ID is the number of characters following the length. Note that the device ID may not be limited to number values.Following the device ID is the length of the text message and then the text message itself. The text message may be any combination of characters (such as letters, numbers or symbols) and may include spaces.This message contains one word.Here is a sample INVALID message:06 a2b10 09 Im readyThe first two values 06 indicate the device ID length. The device ID is a2b10 which has a length of 5. This does not match the specified length 06. Thus, this is NOT a valid message.This message contains two words.The Message class represents messages in this system. A Message must have a device ID, the length of the ID, the length of the message and the text message being sent in order to be a valid message sent through the system. The Message class must determine if a message is valid in order to send a message. A valid message is one where the device ID length matches the given length in the message string and the text message length matches the length of the supplied text message. The text message consists of one or more words where the length of the text message string is at least one character.Consider the code below:Message msg1 = new Message("08 abc123xy 16 Computer Science"); //creates a new message objectboolean msg1Valid = msg1.isValid(); // returns true for a valid messageString text = "11 radio11a287 14";Message msg2 = new Message(text);boolean msg2Valid = msg2.isValid(); // returns false for an invalid messageMessage msg3 = new Message("04 92a1 16 Computer Science");Message msg4 = new Message("03 x8r 21 Today is a great day!");int numWords = msg4.wordCount(); //returns 5, the number of words in the//text messageComplete the Message class by writing the isValid() and wordcount() methods.public class Message{private int idLength;private String deviceID;private int msgLength;private String textMsg;public Message(String msg){//implementation not shown}public boolean isValid(){//to be written}public int wordCount(){//to be written} Which is a valid distinction between the catholic church and the eastern orthodox church?
