please help spring break homework!!

The solution is, 12units is the perimeter of AABC.

Here, we have,

Perimeter of ∆ABC = AB + BC + AC

Formula: distance= √(x_2-x_1)²+(y_2-y_1)²

Distance between A(1, 1) and B(4,1):

Where,

AB = √(4-1)^2 + ( 1-1)^2

AB = 3 units

Distance between B(4,1) and C(4,5)

Where,

BC = √(4-4)^2 + (5-1)^2

BC = 4 units

and, we have,

AC = 5 units

so, we get,

Perimeter of ∆ABC = 3+4+5

                                    = 12 units

Step-by-step explanation:

Please be mad if im  wrong

Answer:

Number 1 is: 120

Number 2: is 42

Number 3 is:27

Step-by-step explanation:

How to solve number 1 is to multiply 4 times 5 then multiply it by 6 and that is how you get 120

How to solve number 2 Multiply 3 times 2 then you get 6 then you do 6 times 7 and that is how you get 42

How to solve number 3 Multiply 3 times 3 then you get 9 then 9 times 3 equals 27

That is how you solve hope this help :)

Answer:

1. 3x + 2

2. 0.25x - 6.5

3. $5.50 per sandwich

Step-by-step explanation:

1.

6x + 1 - (3x - 1)

PEMDAS says solve everything in the parentheses first

There is nothing left to simplify within the parentheses.

Since there's also no exponents, multiplication, or division, let's combine like terms starting from left to right

6x - 3x + 1 + 1

Negative + Negative = Positive, hence why it became 1 + 1

3x + 2

2.

(3x - 1) - 2.75 (x + 2)

PEMDAS says to do multiplication next (since parentheses are fully simplified and there are no exponents)

(3x - 1) - 2.75x - 5.5

Negative + Positive = Negative, hence why it became -5.5

3x - 1 - 2.75x - 5.5

Combine like terms

3x - 2.75x - 1 - 5.5

0.25x - 6.5

3.

Set up an equation:

Variable x = cost of sandwiches

4x + 4(2) = 30

4x + 8 = 30

Subtract 8 from both sides to isolate the variable

4x + 8 - 8 = 30 - 8

4x = 22

Divide both sides by 4

4x ÷ 4 = 22 ÷ 4

x = 5.5

Answer: 23x + 62

Step-by-step explanation: First multiply 5 and 4x which you should get 20x, then multiply 5 and 12 which is 60 and add it to your expressions which looks like 20x + 60 + 3x + 2. Then your going to add 60 and 2 and get 62, lastly add 20x and 3 together and get 23x, So your new expression should look like 23x + 62

Answer:

the first one

Step-by-step explanation:

the reason this is because it is showing a linear graph and when it comes to correlation it has to be linear

The scatter plots shows the strongest correlation in graph A. Therefore, option A is the correct answer.

Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.

A strong positive or negative correlation graph is where the line touches or is very close to every data point, and the line has a positive or negative slope.

From the graph A, we can see the points are closely aligned.

Therefore, option A is the correct answer.

Answer:

1st Question:

m<1 = 90°

m<2= 79°

m<3= 101°

2nd Question:

m<1=97°

m<3=83°

m<6=83°

Step-by-step explanation:

1st Question :

m<1 is a right angle.

m<2 is 79° because of parallel line denote the same angle.

m<3 is 101° because 180°-79°=101°.( As we know sum of angles in a straight line = 18° degree. )

2nd question:

m<1 is 97° because sum of angles in a straight line = 180°

                    So, 180°-83°=97°

m<3 is 83° because sum of parallel sides are equal.

m<6 is 83° because sum of parallel sides are equal.

Answer:

x = -6

Step-by-step explanation:

1. always group the unknowns in this case, we 'bring' over the -2x to the right side so it becomes

-10 = 2x + 2x +14

2. Move 14 to the left side,

-10 - 14 = 2x + 2x

3. Carry out addition on both sides,

-24 = 4x

4. Simplify: since 24 is divisible by 4, so we divide 4 on both sides

-6 = x

Answer: x=-6.

Step-by-step explanation:

First, we need to choose an x side, and a non-x side. Let's choose the right side as the x side since it's coefficient of x is greater than that of the left side. So, we add 2x on each side to get rid of the x on the left side. Now, we have -10=4x+14. Next, we should subtract 14 from each side to get rid of the non-x terms on the right side. Now, we are left with -24=4x. Finally, we can divide by four on each side to get x=-6.

Answer:

x = 7

y = 11

Step-by-step explanation:

Given the system;

y = 2x - 3

x + y = 18

1. Approach

The easiest way to solve this system of equations is to solve the second equation for the variable (y). Then add the systems, use algebra to solve for the value of (x), then substitute that value back into one of the original equations to solve for the value of (y). Another name for the method in use is the method of elimination, this is when a [erspm manipulates one of the equations in a system of the equation such that when they add the equations, one of the variables eliminatates. Thus, they can solve for the other variable and the backsolve for the value of the unknown variable.

2. Solve one of the equations for a variable

Manipulate the system such that each equation is solved for the same variable,

x + y = 18

Inverse operations,

x + y = 18

-18        -18

x + y - 18 = 0

   -y         -y

x - 18 = -y

3. Use elimination

Now substitute this back into the original system,

y = 2x - 3

-y = x - 18

Add the systems,

y = 2x - 3

-y = x - 18

_________

0 = 3x - 21

Inverse operations,

0 = 3x - 21

+21       +21

21 = 3x

/3    /3

7 = x

4. Find the value of the unknown variable

Backsovle to find the value of (y),

x + y = 18

Substitute,

7 + y = 18

Inverse operations,

7 + y = 18

-7        -7

y = 11

Answer:

X=3 Y=15

Step-by-step explanation: First you need to use the problem 18/2=x to find the value of x. Now to find the value of y, you need to subtract 3 from 18.  Then you solve

15=2(9)-3 15+3=18

b.cost of party

c=20f

Step-by-step explanation:

so we know the equation we have to use is c=20f

for part 2 we have to find out how much it's going to cost hank if 50 people attend his party;

so we know that 'c' is our unknown variable; now we write the equation filling in the 'blanks' with what we know-

c=20*50

now we multiply **remember that when you have a number and a letter right next to each other that they're being multiplied**

20*50

=1000

so hank will be spending $1000
