How I Do This Yall..?

Answers

Answer 1

Solve for nn by simplifying both sides of the equation, then isolating the variable.

n=4, −2

Answer 2

Answer:

We know that a modulus gives us the absolute value of a number

Hence,  this modulus will give a positive value, regardless of the actual value in the modulus

| -1 + n | = 3

(-1 + n) or (1 - n) = 3 -------------------This tells us that either one of the values will          give us the same answer

-1 + n = 3   or   1 - n = 3

n = 4          or   n = -2

2/3 of the people in the group came in blue cars and 1/8 of them came in red cars they were 48 people in the group so how many people came in red or blue cars

Answers

Answer:

32 people came in blue cars and 6 people came in red cars

Step-by-step explanation:

Technically, all 48 people came in red or blue cars, but I'm assuming that's not what the question is asking.

To find how many people came in blue cars, we do 2/3*48 which is equal to 32 people.

To find how many people came in red cars, we do 1/8*48 which is equal to 6 people.

Answer:                                        13

-4 (-3x-2)+4=60 can you help me plz ​

Answers

x = 4.

You have to distribute by multiplying -4 by the numbers between -3x and -2.

12x + 8 =60

Subtract the 8 from 60 to simplify the equation.

12x = 48

Divide 12 by 48 and get 4.

Solve the following equation for A. Be sure to take into account whether a letter is capitalized or not. b=f^2A+2HA

Answers

Answer:

A = [tex]\frac{b}{f^2+2H}[/tex]

Step-by-step explanation:

Given equation is,

b = f²A + 2HA

To solve this equation for the value of A we will isolate A in one side of the equation.

b = A(f² + 2H)

By dividing the equation by (f² + 2H) on both the sides of the equation.

[tex]\frac{b}{f^2+2H}=\frac{A(f^2+2H}{(f^2+2H)}[/tex]

A = [tex]\frac{b}{f^2+2H}[/tex]

Therefore, answer will be A = [tex]\frac{b}{f^2+2H}[/tex]

Answer:

If Kasey bought one drink, she will be able to buy 6 food items

Step-by-step explanation:

We know Kasey has $8 and if she bought one drink, she will have $7.5

We have to find how many food items she can buy (all of them are $1.25)

$7.5/1.25= 6 food items

If Kasey bought one drink, she will be able to buy 6 food items

Hope this helps!

Answer:

6 items

Step-by-step explanation:

8.00 - 0.50 = 7.50

She has $7.50 to spend on food after buying one drink

7.50 ÷ 1.25 = number of food items she can buy

7.50 ÷ 1.25 = 6

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends. If he works 6 hours on the weekend in addition to 35 hours during the week, how much does he earn?

Answers

Answer:

$513.75

Step-by-step explanation:

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.

$498.75 + $2.50 × x

If he works 6 hours on the weekend in addition to the 35 hours during the week:

$498.75 + $2.50 × 6

= $498.75 + $15

= $513.75

Find the sum of -9X + 13 and -16x - 6
A.-25x +7
B. 25x -7
C.-25x-7
D.25x+7

Answers

Answer:

A. -25x + 7

Step-by-step explanation:

First, to answer this question, we will combine the two sides of the equation:

(-9x + 13) + (-16x - 6)

Now, we take away the parentheses and add like terms:

-9x + 13 + -16x - 6 =

-25x + 7

So, the answer would be A. -25x + 7

Jeff is building a bookcase for his room and wants to be sure the shelves are parallel. He measures the angles below and knows the shelves are parallel when he finds which two angles to be supplementary?

Answers

Answer:

∠2 and ∠4 are the supplementary angle.

Step-by-step explanation:

Shelves of the bookcase are parallel and a transversal line is intersecting these points at two distinct points.

By the property,

Sum of two interior consecutive angles measure 180°.

From the figure attached,

∠2 and ∠4 are the interior consecutive angles.

Therefore, m∠2 + m∠4 = 180°

Which proves that shelves of the showcase are parallel.

This story originally appeared in Chatterbox, a book of stories edited by J. Erskine Clarke.Which line from the story supports the idea that Fred is a courageous boy?It was Saturday afternoon when the boys of Wedderburn School went off as usual to swim their boats on a beautiful lake. Fred Langton had a new boat, which his grandfather had sent to him as a birthday present. It was a larger and better-constructed boat than any of the others. Each boy was, of course, eager that his own boat should win the race. Although all the boys admired Fred's boat and wished that they could have had one as good, they felt no grudge towards Fred himself. In fact, he was a general favorite in the school. He was kind-hearted, unselfish, and always willing to give anything that he had to his companions.I tell you, said Bill Cowan to his own particular chum, Joe Morris, that boat of Fred's will beat ours all hollow! I wish I had one as good!Well, suppose it does win, replied Joe Morris, I shall not grudge it to him, for Fred is no sneak; he is out-and-out the jolliest fellow in Wedderburn School.So he is, said Bill Cowan, and no mistake about it. Well, here we are at the lake, and now for some fun.On this particular Saturday, however, Fred was going to become famous in quite another way. The little boats were all in full sail, and the schoolboys were shouting with glee at the fun. Suddenly a fox-terrier took it into his head to chase the boats and show that he could swim as well as they could. Poor dog! It was quite true that he could swim. Unfortunately he got caught among weeds. He began struggling in the water and barking for help.Oh, I say, I can't stand this! cried Fred Langton; he will be drowned. I must go in and fetch him out!No, no! cried Bill Cowan; the lake is quite deep just at that place.Yes, I know it's deep, added Joe Morris, and, besides, you can't swim, Fred; don't be silly. Who cares for a dog being drowned?I do, for one, cried Fred, and dashing into the water he waded out to where the poor dog was half-standing, half-lying, among the choking weeds. Yes, the water was deep; but stretching out his arms he contrived to catch hold of the poor animal, and he quickly waded back to shore amid ringing cheers from all the people who had now gathered on the bank to watch the plucky lad. And whose was the dog? Nobody knew; it seemed, indeed, to have no owner and no home. But Fred and his companions carried it back with them to the school, and, after having told their tale, they begged the head master to keep it for himself. As Dr. Williams could not discover anything about the dog's ownership, he did keep it. So Fred's brave deed not only saved the animal's life, but procured a good home for it as well. what of the following are functions of lipids? choose three correct answers derive ideal gas equation for n mole of gas. which one of these situations is commonly caused by acid rain?a. people being poisoned by drinking water b. fish and birds in freshwater habitats dying offc. people receiving acid burns on there skind. whales and dolphins dying off in the oceans What value of x makes this equation true?need done fast please, offering 25 points!
