Can someone isolate the variable “n” and show steps?

Answer:

look below

Step-by-step explanation:

To round a number to the nearest tenth , look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.

Answer:

22 days

Step-by-step explanation:

Given data

Number of students= 50

Number of days= 32days

We want to find the number of students that can have food for 14days

If 50 students will have food for 32 days

x students will have food for 14 days

cross multiply

32*x= 14*50

32x= 700

x= 700/32

x=21.8

Hence 14 students will have for 22 days

Answer:

15 students do not like either sport

Step-by-step explanation:

See the attached image.

Step 1: put 35 in the "like to play both" (intersection) area.

Step 2: subtract those 35 from the 65 football players.  65 - 35 = 30 players like football but not cricket.  Put 35 in the football but not cricket area.

Step 3: subtract 35 from the 55 cricket players.  55 - 35 = 20 players like cricket but not football.  Put 20 in the cricket but not football area.

Step 4: Add the 30 + 35 + 20 = 85 together.  So 85 players are accounted for as players of one or more sports.

Step 5: 100 - 85 = 15 must be the number of students who did not like either sport.  Put 15 in the area outside both circles.

Answer:

movement in the tectonic plates in the crust, wind and water erosion, and deposition shapes the earth's surface

Step-by-step explanation:

Answer:

Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.

Step-by-step explanation:

Answer:

7. x = 38°

8. y = 65°

9. 261° and 81°

Step-by-step explanation:

Finding x:

You can make an equality with (2x +5) and (3x +33) because the value of these angles are the same, so:

2x +5 = 3x -33

2x - 3x = -33 -5

-x = -38

x = 38°

Finding y:

You can find the value of y making another equally, but this time you have to sum (4y -1) with (3x - 33) or (2x +5) and equal it with 180°:

(4y -1)+(2x +5) = 180

4y -1 +2x +5 = 180

4y +2x +4 = 180

We know from the question 7 that x is 38°:

4y +2•(38) +4 = 180

4y - 76 +4 = 180

4y - 80 = 180

4y = 180 + 80

4y = 260

y = 260/4

y = 65

Finding the value of the angles:

You just have to put the value of x and y in their places and make the calculations:

4•65 +1 = 261°

3•(38) -33 = 81°

Step-by-step explanation:

Slope is rise over run

Looking at the graph we know the slope is positive since it goes up from left to right

Answer:

96 students

Step-by-step explanation:

x + y = 323

2x + 3.5y = 790

=> by elimination

2x+3.5y=790

2x+ 2y = 646

__________-

1.5y = 144

y = 144/1.5 = 96

The system of equations are

x + y = 323

2x + 3.5y = 790

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the system of equations be A and B

Now , the number of tickets sold = 323 tickets

Let the number of students be = x

Let the number of non students = y

So , x + y = 323   be equation (1)

The cost for students = $ 2

The cost for non students = $ 3.50

The total cost of all the tickets = $ 790

So , 2x + 3.5y = 790   be equation (2)

On simplifying the equations , we get

Multiply equation (1) by 2 , we get

2x + 2y = 646   be equation (3)

Subtracting equation (3) from equation (4) , we get

1.5y = 144

Divide by 1.5 on both sides of the equation , we get

y = 96

So , the number of non students be y = 96

Substituting the values of y in equation (1) , we get

x = 323 - 96 = 227 students

Now , the graph of the equations is plotted and the point of intersection is the solution ( 227 , 96 )

Hence , the equations are solved
