Solve for M
-7+4m+10=15-2m

Answers

Answer 1

Answer:

m=2

Explanation:

see .pdf file

Answer 2

Answer:

m=2

Step-by-step explanation:

-7+4m+10=15-2m

We move all terms to the left:

-7+4m+10-(15-2m)=0

We add all the numbers together, and all the variables

4m-(-2m+15)-7+10=0

We add all the numbers together, and all the variables

4m-(-2m+15)+3=0

We get rid of parentheses

4m+2m-15+3=0

We add all the numbers together, and all the variables

6m-12=0

We move all terms containing m to the left, all other terms to the right

6m=12

m=12/6

m=2

how do you change y – 5 = - (x – 1) into slope intercept form?

Answers

Answer:

y = -x + 6

Step-by-step explanation:

Slope intercept form is y = mx + b.

So distribute the negative sign on the right side to get:

y - 5 = -x +1

Then  add the 5 on the left side to both of the sides to get y alone, then you will get:

y = -x +6

That is in slope intercept form.

Y=-x+6 plz give me brainlist :(

Wednesday morning, the temperature was −12 ∘F. By the afternoon, the temperature was 23 ∘F. Write and then evaluate a subtraction expression to determine the number of degrees of change in temperature between the morning and the afternoon.

Answers

23-12=11 11 degrees should be the answer

The change in temperature between the morning and the afternoon would be 35° F.

What is the Subtraction operation?

Subtraction is a mathematical operation that deducts the right-hand operand from the left-hand operand.

We have been given that Wednesday morning, the temperature was −12° F. By the afternoon, the temperature was 23° F.

We have to determine the change in temperature between the morning and the afternoon

As per the given question,

Here, final temperature = 23° F and initial temperature = −12° F

The change in temperature = final temperature -  initial temperature

The change in temperature =  23° F - ( -12° F )

Apply the subtraction operation,

The change in temperature =  23° F + 12° F

The change in temperature =  35° F

Hence, the change in temperature between the morning and the afternoon would be 35° F.

Solve the equations in Parts A and B using inverse operations. Check your solutions. In your final answer, include all of
your work
Part A: 5 + 2 = 232 + 13
Part B:5 + 1 = 23% + 13

Answers

Answer:

Part A: 7 = 245

Part B: 6 = 1323/100

Step-by-step explanation:

Part A: Add the numbers 5 and 2 which you get 7 and then you add 232 and 13 which gives you 245

equation version: 5 + 2 = 7

232 + 13 = 245

7 = 245

Part B: In order to convert a precent to a ratio, divide it by 100

23/100

5 + 1 = 23/100 + 13

5 + 1 = 6

23/100 + 13 = 1323/100

6 = 1323/100

HELP PLZZZZZ I AM GIVING BRAINLIEST HURRY HURRY ASAP HELPPPP Read this short passage and answer the question below:Excerpt from The Little MermaidBy Hans Christian Andersen"Come, little sister," said the other princesses; then they entwined their arms and rose up in a long row to the surface of the water, close by the spot where they knew the prince's palace stood. It was built of bright yellow shining stone, with long flights of marble steps, one of which reached quite down to the sea. Splendid gilded cupolas rose over the roof, and between the pillars that surrounded the whole building stood life-like statues of marble. Through the clear crystal of the lofty windows could be seennoble rooms, with costly silk curtains and hangings of tapestry; while the walls were covered with beautiful paintings which were a pleasure to look at. In the center of the largest saloon a fountain threw its sparkling jets high up into the glass cupola of the ceiling, through which the sun shone down upon the water and upon the beautiful plants growing round the basin of the fountain. Now that she knew where he lived, she spent many an evening and many a night on the water near the palace. She would swim much nearer the shore than any of the others ventured to do; indeed once she went quite up the narrow channel under the marble balcony, which threw a broad shadow on the water. Here she would sit and watch the young prince, who thought himself quite alone in the bright moonlight. She saw him many times of an evening sailing in a pleasant boat, with music playing and flags waving. She peeped out from among the green rushes, and if the wind caught her long silvery-white veil, those who saw it believed it to be a swan, spreading out its wings.Based on details in the story, the reader can conclude that the little mermaid A) cares more about humans than her sisters do B) loves the beauty of the princes palace more than her home C) is unhappy with her life below the sea D) is too shy to try and talk to the prince Solve the inequality.||2x1|2|>3 what isotope has a mass number of 18 and an atomic number of 7 Prove: (1+tan)/(1+cot )=sec/csc You learned skill-related and health-related fitas components.
