Answer:

1st scenario: 163.3°

2nd scenario: 125.2°

3rd scenario: 142.3°

Step-by-step explanation:

1st scenario: angles 1 and 2 form a linear pair and add up to 180

2nd scenario: angles 1 and 4 are same-side interior and add up to 180

3rd scenario: angles 1 and 8 are corresponding and equal; if angle 7 is 37.7 then angle 8 is 142.3 (they form a linear pair). Since angles 1 and 8 are equal then angle 1 is also 142.3

Blank 1 = 3Blank 2 = 3

In other words, x = 3 and y = 3

===========================================================

Explanation:

Let's solve the first equation for x. I'm picking on this equation variable because the coefficient is 1.

Solving for x leads to

x-2y = -3

x = -3+2y

I added 2y to both sides

Now we'll plug this into the other equation. This means we replace every copy of x with -3+2y since they are the same thing.

3x + 5y = 24

3( x ) + 5y = 24

3( -3+2y ) + 5y = 24 .... replace x with -3+2y

3(-3) + 3(2y) + 5y = 24 .... distribute

-9 + 6y + 5y = 24

11y-9 = 24

11y-9+9 = 24+9 ...... adding 9 to both sides

11y = 33

11y/11 = 33/11 .... dividing both sides by 11

y = 3

We'll use this y value to find x. We can pick on any equation with x & y in it, but I find it's easiest to use the equation where x is isolated

x = -3+2y

x = -3+2(3) .... replace y with 3

x = -3+6

x = 3

So both x and y are equal to 3

-------------------------------

Let's check the answer

Plug (x,y) = (3,3) into the first equation. We should get the same number on both sides after simplifying fully

x-2y = -3

3 - 2(3) = -3

3 - 6 = -3

-3 = -3

So far, so good. Let's try the other equation

3x + 5y = 24

3(3) + 5(3) = 24

9 + 15 = 24

24 = 24

The other equation is true as well. This fully confirms that (x,y) = (3,3) is the solution to this system of equations. If you graphed each original equation, you should find they cross at the location (3,3).

Side note: it won't always be the case that x and y are the same value.

Every week, Fred deposits $84 into his savings account, which is 20% of his weekly income. How much income does Fred make each week?

Answers

Answer:

Fred's monthly income is $420.

Step-by-step explanation:

There are two main ways of solving this. There are many ways of solving for this, but personally I like to do divide the percentage by 100 so it would look something like this-

100/20 = 5.

Then I multiply $84 by 5 which is $420.

Answer:

ze answer is 420 since 84 is 20% of 100 and 20 x 5 - 100 so,84 x 5 = 420

I need to know how to show the work to get this answer

Answers

Answer:

10/3

Step-by-step explanation:

Simplifying 2b - (3-b) gives us:

2b - (3 - b) =

2b - 3 + b =

3b - 3

This makes our new equation:

3b - 3 + 4 = 11

Combine like terms

3b + 1 = 11

Subtract 1 from both sides

3b = 10

Divide both sides by 3

b = 10/3

option B , x = 6 is the correct answer of this question .

Hope this will be helpful to you plz mark my answer as brainlist ..

Answer:

b. x = 6

Step-by-step explanation:

Solve for x :

10(x + 2) - 15 = 65

To solve this we need to isolate x :

Distribute the ten to both numbers within the parenthesis :

(10(x) + 10(2)) - 15 = 65

10x + 20 - 15 = 65

Order of operations :

10x + 5 = 65

Subtract 5 from both sides :

10x = 60

Divide 10 by both sides :

x = 6

Today a lake in Minnesota is named Sourdough Lake.A Giant of a ManA big burly man dressed as a lumberjack stands next to a big ox and holds an ax over his shoulder.Back in 1913, I worked on one of Paul Bunyans famous crews. Let me tell you, there are many good tales about the legendary Paul Bunyan, but they dont tell half the story. He was a giant of a man who could pick up four horses with their load of logs and turn them around on the road. He led crews of us loggers to hew trees and chop them into logs during the days when this country was growing fast.Feeding Bunyans crews of ravenous loggers was a big job. Pauls cook Big Joe wanted a griddle to cook pancakes. So, Big Ole, the blacksmith, made an immense griddle. The pancake batter was stirred in machines like concrete mixers. It was poured on the griddle with cranes.One year, everything got buried during the Winter of the Deep Snow. It was quite a predicament. Paul dealt with the challenge by digging down to find the tops of the tall pine trees and lowering his loggers to chop logs. His blue ox, Babe, wore snowshoes to haul the wood to the surface of the snow.Paul had a cow named Lucy. She had the appetite of a wolf. In the winter of the Deep Snow, the loggers gave Lucy a pair of Babes old snowshoes and green goggles. They turned her out to graze in the snow. She learned to run in the snowshoes, and she ran all over North America.One of Pauls loggers took a load of logs down the Mississippi River for Paul. When the logs were delivered, they were the wrong logs. Paul had to get them back upstream. Driving logs upstream is impossible, but an impossible job never stopped Paul. He fed Babe salt and took him to the upper Mississippi to drink. Babe drank the river dry, and the logs traveled up the river faster than they had gone down.Paul could solve problems like no one else I ever knew or you ever heard of. In the Winter of the Blue Snow, Shot Gunderson was in charge of the Big Tadpole River area. He chopped his logs so that they landed in a lake. He planned to move them in the spring. To his surprise, when he tried to move the logs, he discovered the lake had no outlet to the river. He thought the whole winters work was lost. But Paul was always clever. He came up with an ingenious idea. He called in Sourdough Sam, a cook who made everything out of sourdough except the coffee. Paul ordered him to mix enough sourdough to fill the big water tank. Then he hitched Babe the Blue Ox to the tank and dumped the sourdough into the lake. Dough rises. As Sam said, it riz and pushed the logs over the hills that surrounded the lake. They rolled all the way to the river. Today a lake in Minnesota is named Sourdough Lake. These colonist wanted to remain loyal to Britain.1. patriots2. loyalists3. neutralists4. separatistsWhich one?
