Find the value of X

Answers

Answer 1

Answer:

Step-by-step explanation:

This is a 5 sided shape, aka a pentagon, and we know that five sided shape's angles add up to 540, so our equation is:

(9x-6)+(3x+23)+95+(7x-4)+90=540.

Combine like terms:

We get 25x+90=540

x = 18

Find the solution to the system. Write your solution as an ordered pair (x,y)
with no spaces, no solution, or infinitely many. x-3y=7 and 3x-9y=21*

Answers

Answer:

Infinitely many

Step-by-step explanation:

If we multiply the equation x-3y=7 by 3, we get 3x-9y=21, which is also the second equation. That means the two lines are on top of each other, meaning infinite many solutions.

what is 246 : 7 in long division

Answers

Here we will show you step-by-step with detailed explanation how to calculate 246 divided by 7 using long division.

Before you continue, note that in the problem 246 divided by 7, the numbers are defined as follows:

246 = dividend

7 = divisor

Step 1:

Start by setting it up with the divisor 7 on the left side and the dividend 246 on the right side like this:

7 ⟌ 2 4 6

Step 2:

The divisor (7) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:

7 ⟌ 2 4 6

Step 3:

Multiply the divisor by the result in the previous step (7 x 0 = 0) and write that answer below the dividend.

7 ⟌ 2 4 6

Step 4:

Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.

7 ⟌ 2 4 6

- 0

Step 5:

Move down the 2nd digit of the dividend (4) like this:

7 ⟌ 2 4 6

- 0

2 4

Step 6:

The divisor (7) goes into the bottom number (24), 3 time(s). Therefore, put 3 on top:

0 3

7 ⟌ 2 4 6

- 0

2 4

Step 7:

Multiply the divisor by the result in the previous step (7 x 3 = 21) and write that answer at the bottom:

0 3

7 ⟌ 2 4 6

- 0

2 4

2 1

Step 8:

Subtract the result in the previous step from the number written above it. (24 - 21 = 3) and write the answer at the bottom.

0 3

7 ⟌ 2 4 6

- 0

2 4

- 2 1

Step 9:

Move down the last digit of the dividend (6) like this:

0 3

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

Step 10:

The divisor (7) goes into the bottom number (36), 5 time(s). Therefore put 5 on top:

0 3 5

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

Step 11:

Multiply the divisor by the result in the previous step (7 x 5 = 35) and write the answer at the bottom:

0 3 5

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

3 5

Step 12:

Subtract the result in the previous step from the number written above it. (36 - 35 = 1) and write the answer at the bottom.

0 3 5

7 ⟌ 2 4 6

- 0

2 4

- 2 1

3 6

- 3 5

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 246 divided by 7 calculated using Long Division is:

. Which of the following situations is best represented by the equation y = x + 15?

1 Each student begins the candy hunt with 15 pieces of candy in their bag.
2 Emery earns $15 per hour babysitting.
3 Joshua spent $15 of his money at the movie theatre.
4 Each homeroom class has at least 15 students.

Answers

Step-by-step explanation:

= 30 djdjsbdjdbdbdu djsjsbs

I say that A best represents the equation.

The reason I say this is because the equation (y= x + 15) can be explained like this.

y= Total amount of candy (in this case since it's based on A)

x= Amount found (normally would be called earned)

15= starting amount (aka initial value)

So since each student started with 15 you would add that on to X= the total amount found. Then after that the total value (y) would have been represented by the equation X + 15.

All in all A best represents the equation Y= X + 15.

Hope this helps.

PLEASE HELP ASAP, I HAVE 10 MINUTES ;
Arianna and her children went into a grocery store where they sell peaches for $1 each and mangos for $0.50 each. Arianna has $9 to spend and must buy at least 13 peaches and mangos altogether. If x represents the number of peaches purchased and y represents the number of mangos purchased, write and solve a system of inequalities graphically and determine one possible solution.

Answers

Answer:

Step-by-step explanation:

when 13 bought we find these inequalities

x + 12y < 7 no

2x + 11y < 7.5 no

3x + 10y < 8 no

4x + 9y < 8.5 no

5x + 8y > 9 yes

When 14 bought we find these inequalities

x + 13y < 7.5 no

2x + 12y < 8 no

3x + 11y < 8.5 no

4x + 10y > 9 yes

We want to find and solve a system of inequalities to determine some possible solutions to Arianna's situation.

The possible solution is:

x = 2

y = 12

And the graph can be seen at the end.

Now let's see how to solve this.

First, we need to write the system of inequalities, the information given is:

Price of each peach = $1.Price of each mango = $0.50Arianna has $9.Arianna must buy at least 13 fruits.

Now we can define the variables:

x = number of peaches that she buysy = number of mangos that she buys

Then we must have:

x + y ≥ 13 (this means that she buys at least 13 fruits)

x*$1 + y*$0.50 ≤ $9 (this means that she can't spend more than $9)

Now we just need to graph these two lines, we can rewrite them as:

y ≥ 13 - x

y ≤ $9.00/$0.50 - x*$1/$0.50 = 18 - x*2

Then we just need to graph the two lines, and shade the region above the first one, and the region below the second one, the graph can be seen below:

Any point inside the double shaded region in the first quadrant is a possible solution. (we restrict only to the first quadrant because we can not use negative values for x nor for y).

Then a possible solution that we could choose is:

x = 2

y = 12

This means that she buys 2 peaches and 12 mangos.

You are painting a room that is 16 feet long, 10 feet wide, and 8 feet high. On the walls of the room, there are two windows that are each 2 feet wide and 5 feet tall, and a door that is 4 feet wide and 7 feet tall. A gallon of paint covers 350 square feet. How many gallons of paint do you need to cover the 4 walls with one coat of paint, not including the windows and the door

Answers

You will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.

Given that,

Room dimensions:

Length: 16 feet

Width: 10 feet

Height: 8 feet

Features on the walls:

Two windows:

Width: 2 feet

Height: 5 feet

One door:

Width: 4 feet

Height: 7 feet

Paint coverage:

1 gallon of paint covers 350 square feet

Calculate the area of the walls first:

Subtract the area of the windows and door area from the total wall area.

The total wall area is the sum of the areas of all four walls.

The area of each wall is calculated by multiplying the height of the room by its length.

So, the area of each wall = 8 feet (height) x16 feet (length)

The area of each wall = 128 square feet.

Calculate the area of the windows and the door.

The area of each window is calculated by multiplying its width by its height.

So, the area of each window = 2 feet (width) x 5 feet (height)

The area of each window = 10 square feet.

The area of the door is calculated by multiplying its width by its height. So,

The area of the door = 4 feet (width) x 7 feet (height)

The area of the door = 28 square feet.

Now, subtract the total area of the windows and the door from the total wall area.

Total wall area = 4 walls x 128 square feet

Total wall area = 512 square feet

The total area of the windows = 2 windows x 10 square feet

The total area of the windows = 20 square feet

The total area of the door = 1 door x 28 square feet

The total area of the door = 28 square feet

Area to be painted = Total wall area - Total area of the windows - Total area of the door

Area to be painted = 512 square feet - 20 square feet - 28 square feet

Area to be painted = 464 square feet.

Now, we can determine the number of gallons of paint needed.

Since 1 gallon of paint covers 350 square feet,

Divide the area to be painted by 350.

The number of gallons of paint needed = Area to be painted / Coverage per gallon

The number of gallons of paint needed = 464 square feet / 350 square feet/gallon

The number of gallons of paint needed ≈ 1.33 gallons.

Hence, you will need approximately 1.33 gallons of paint to cover the four walls with one coat, not including the windows and the door.

We assume your intended quotients are ...

49 ÷ 7 = 7

0.49 ÷ 0.7 = 0.7

0.049 ÷ 0.07 = 0.7

The one that is different is 49 ÷ 7.

Evaluation of the quotients tells you which is different. Inspection of place values also tells you which is different. In all but the first quotient, the 4 and the 7 are in the same number place, so the quotients will be the same value.
