Answer:

Output = input + 2

Step-by-step explanation:

Simple, take some values to figure it out.

When input is 0, output is 2

When input is 1, output is 3

When input is 2, output is 4

When input is 3, output is 5

There is one commonality between them:

The output is simply input + 2

mora bought 3 bags of appkes for her class. one full bag has 8 apples, and each apple weighs 6 ounces. write a numerical expression to represent this situation.

Answers

Mora bought 3 bags of apples for her class, one full bag has 8 apples, and each apple weighs 6 ounces, the numerical expression to represent this situation is, Total weight = N × n × w =3 × 8 × 6

What are expressions?

An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

Mora bought 3 bags of apples for her class

One full bag has 8 apples

Each apple weighs 6 ounces

we have to write expression for total weigh carries by Mora,

Suppose, Total weigh is W

one bag has apples = n

Each apples weigh is w

Number of bags is N

Expression;   Total weight = N × n × w

Therefore, the expression is, Total weight = N × n × w =3 × 8 × 6

Answers

The area of rectangle ABCD is 104 square units.

What Is the Area of a Rectangle in Geometry?

The area of the space occupied within the perimeter of a rectangle is called the area of a rectangle. It is calculated by finding the product of the length and breadth of the rectangle.

What Is the Perimeter and Area of a Rectangle?

The perimeter of a rectangle is the sum of its four sides. Hence, Perimeter of Rectangle = 2 (Length + Width) units. The area of a rectangle is defined as a product of length and width. It is expressed in terms of squareunits.

Step-by-step explanation:

Darcy, Jason and Maria share.$268. Jason has $20more than Darcy and Maria has twice as much money as Jason. How much money do Darcy and Jason have altogether?

Answer:

$124.

Jason- 20$ more than Darcy

Maria- Twice as much as Jason

Darcy- 20$ less than half of Maria's sum.

Step-by-step explanation:

After I had written the page below, I came back up here and realized there was a much easier way.

268/2 = 134

Since the 20 Is added after, half is subtracted and you end up with

124!!

Now for my explanation done first, typed and read as I figured it out.

First and mostly, we need to find what Darcy starts with.

Let's say that Darcy has 5 dollars, to start somewhere easy. That would mean that Jason has 25 dollars since he has 20 more than her. That would mean that Maria would have 50 dollars, and the looted sum is 80.

Since that is less than a quarter of our end goal of 268$, I raised Darcy's initial amount of money to 15 to triple her money.

Math revised here- 15+20= (35*2) 70= 120

15+35+70

Since that is too low, I'm adding it to 30$.

Math revised again here- 30+20=(50*2)=100= 180

30+50+100

  5      15      30

 80    120    180

That is a chart determining our answers so far. There is no clear pattern, so let us continue.

Darcy starts with 50 dollars for this one.

50+20=(70*2)=140

50+70+140

260.

We are close to the sum.

Darcy starts with $52

52+20(72*2)= 144

52+72+144

268!

This means we have found how much Darcy has, and since Jason's amount depends on her, we have found both of their sums!

815 gal/h convert to qt/sec

Answers

Answer:

0.905 qts/s

Step-by-step explanation:

First we have to know the equivalent of each unit

1 gal is equal to 4 qt

1 hour is equal to 3600 sec

Now we have to order each of the units 815 (gal)/(h)(4 qt)/(1 gal) *(1 h)/(3600 sec)

(815 gal*4 qt)/(1 gal) =3260 in this step the gal are eliminated

Now we have to convert the seconds

(3260 *1 hour)/(hour*32600 sec)  =0.905

Now we convert the hour to seconds

so the answer is 0.905qt/sec

(815*4÷60) qt/ (60÷60) sec

What is the solution to the linear system of equations? y = 3x + 1 y = –x + 5

Answers

y = 3x + 1
y = –x + 5

3x + 1 = -x + 5
4x + 1 = 5
4x = 4

x = 1

y = 3(1) + 1
y = 3 + 1
y = 4

The solution to the linear system of equations is (1, 4).
