When would there be only four different equations for a set of math mountain numbers?

Only when any equation you find among those numbers can be simplified into one of the four main equations, wich means you only have four different true statements, and lots of equivalences.

Only when any equation you find among those numbers can be simplified into one of the four main equations, which means you only have four different true statements and lots of equivalences.
For example,
20 + 20 = 40
40 - 20 = 20
40 = 20 + 20
20 = 40 - 20.
As the two addends are the same, so there would be only four different equations for a set of math mountain numbers.

Find the dimensions of a rectangle with perimeter 76 m whose area is as large as possible. m (smaller value) m (larger value)

Sladkaya [172]

Answer:

19 m

Step-by-step explanation:

Perimeter = 2(length + width) ; P = 2(l+w) - - (1)

Area = Length * width ; A = l*w - - - (2)

76 = 2(l+w)

76/2 = l+w

l+w = 38

l = 38 - w

Put l = 38 - w in (1)

A = (38-w)*w

A = 38w - w²

At maximum point:

dA/dw = 0

dA/dw = 38 - 2w

38 - 2w = 0

38 = 2w

w = 38/2

w = 19

In line 17, "summons" most nearly means

erica [24]

In line 17, "summons" most nearly means calls forth.

"Summon(s)" generally means to call something or someone.
Here, when the writer says "the hubbub summons sense-memories" it means that the hubbub brings to the forefront of his mind the sense-memories.
Thus we can conclude that 'summons' best means 'call forth' in the given context. Thus B is the best answer.

What happens when you get summoned?

A Summons is an invitation to come to court. In some cases, the court will schedule a call or a video call for the first appearance instead.
In other cases, the court will ask that you file an appearance or an answer. Your Summons should say so.

Can summons be Cancelled?

Yes, the summons can be cancelled or quashed as appropriately required by law dependent on the facts of settlement and the terms and conditions determined therein between the parties.
The legal procedure has to be followed for the same.

Solve the system using elimination

Pie

Answer:

(x, y) = (3, 1)

Step-by-step explanation:

given the 2 equations

2x + 3y = 9 → (1)

x + 5y = 8 → (2)

multiplying (2) by - 2 then adding to (1) will eliminate the term in x

multiply (2) by - 2

- 2x - 10y = - 16 → (3)

add 1(1) and (3) term by term

(2x - 2x) + (3y - 10y) = (9 - 16)

- 7y = - 7 ( divide both sides by - 7 )

y = 1

Substitute y = 1 in either (1) or (2) and solve for x

(1) : 2x + 3 = 9 ( subtract 3 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Solution is (3, 1 )

A hudson valley farmer has 26 employees.He pays each employee $410 per week.After paying his workers for one week,the farmer has

Sliva [168]

Hi there!

A valley farmer has 26 employees and he pays each of them $410 per week.

After paying them for one week he has $162 dollars left. We need to find how much money he had at first.

So the first step is to multiply $410 on 26 since he gives 410 dollars to each employee, which he has 26.

$410 · 26 = $10,660

So he had $10,660 before he paid the workers, but he still had $162 left. To find out his overall total of money he had we need to add $10,660 and $162 which will be $10,822.

The farmer had $10,822

Hope this helped!~
