Answer:

x = 0.75

Step-by-step explanation:

Simplifying

(7x + -5) + -1(3x + -2) = 0

Reorder the terms:

(-5 + 7x) + -1(3x + -2) = 0

Remove parenthesis around (-5 + 7x)

-5 + 7x + -1(3x + -2) = 0

Reorder the terms:

-5 + 7x + -1(-2 + 3x) = 0

-5 + 7x + (-2 * -1 + 3x * -1) = 0

-5 + 7x + (2 + -3x) = 0

Reorder the terms:

-5 + 2 + 7x + -3x = 0

Combine like terms: -5 + 2 = -3

-3 + 7x + -3x = 0

Combine like terms: 7x + -3x = 4x

-3 + 4x = 0

Solving

-3 + 4x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 4x = 0 + 3

Combine like terms: -3 + 3 = 0

0 + 4x = 0 + 3

4x = 0 + 3

Combine like terms: 0 + 3 = 3

4x = 3

Divide each side by '4'.

x = 0.75

Simplifying

x = 0.75

Answer:

When solving equations like this, you have to use a method called PEMDAS.

This stands for:

(7x + 5) - (3x +2)

Let's work it out...

Step one) Distribute the equation

Distributing the equation helps simplify it and make solving much easier.

(7x−5) − 1(3x−2)

(7x−5) − 3x + 2

Step two) Eliminate the Parenthesis

Now that the equation is simplified, you can take out the Parenthesis.

(7x − 5) − 3x + 2

7x − 5 − 3x + 2

Step three: Add the numbers

Add the two whole numbers together (-5 + 2)

7x − 5 − 3x + 2

7x − 3 − 3x

Step four: Combine like terms

Combine like terms or the numbers with variables (7x - 3x)

7x − 3 − 3x

4x − 3

Answer:

75

Step-by-step explanation:

You will set the equation up as part/whole = percent/100 and when you replace it with your numbers you get 60/x = 80/100 now you cross multiply and do 60*100 = 80 * x and you get 6,000 = 80x now you divide both sides by 80 then you get 75 was the original price

Step-by-step explanation:

Answer:

8n+16.2=1.6

n=-1.825

Step-by-step explanation: Subtract 16.2 from both sides 8n+16.2-16.2=1.6-16.2

Simplify 8n=-14.6/8

n=-1.825

Answer:

-1.825

Step-by-step explanation:

8n  +  16.2  =  1.6

(step1)      

8n  +  16.2  =  1.6

        - 16.2     -16.2

8n      =      -14.6

(step2)

8n =  -14.6

----    ------

 8      8

(step3)

-1.825

1. subtract 16.2 from both sides, you have to get rid of the number that is being add/subtracted to get the n and result alone

2. divide by the number next to the variable since you have to get the variable alone in order to find out what it is. you divide because you have to do the opposite of what the variable IS doing.

3. get the result lol

Answer:

Step-by-step explanation:

The answer is 175 miles per day. I guessed on it and it was right :D

The number of miles per day that will have to be driven for the total cost of of a car from the first agency to equal the total cost of a car from the second agency is 175.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

A rental car agency charges $16 per day plus 14 cents per mile to rent a certain car. Therefore, we can write,

Total charge for x miles = $16 + $0.14(x)

Another agency charges $23 per day plus 10 cents per mile to rent the same car. Therefore, we can write,

Total charge for x miles = $23 + $0.10(x)

Since it is needed to be found the number of miles that the car should be traveling so that the total cost from both the agencies is the same. Thus, equate the equation together,

$16 + $0.14(x) = $23 + $0.10(x)

16 + 0.14x = 23 + 0.10x

0.14x - 0.10x = 23 - 16

0.04x = 7

x = 7 / 0.04

x = 175 miles per day

Hence, the number of miles per day that will have to be driven for the total cost of of a car from the first agency to equal the total cost of a car from the second agency is 175.

Answer:

8400

Step-by-step explanation:

10800/9= 1200

1200*7= 8400

Answer:

Step-by-step explanation:

Part A

A square pyramid surface area can be calculated using A = Lw (which gives you surface area of the base square) & 4 of A = bh/2 (which gives you surface area of the 4 triangles on the side)

This means overall A = Lw + 4(bh/2)

Length = L = 4"

Width = w = 4"

Base = b = w = L = 4"

Height = h = 6"

A = Lw + 4(bh/2)

A = Lw + 2bh     This is the answer after simplifying

A = (4")(4") + 2(4")(6")      This is the numerical expression.

A = 16" + 48" = 64"    This is the numerical answer.

A square prism surface area can be found using 2 of A = Lw (which represents the surface area of the 2 squares) and 4 of A = Lh (which gives you the surface area of the 4 rectangles).

This means overall A = 2Lw + 4Lh

Length = L = 4"

Width = w = 4"

Height = h = 6"

A = 2Lw + 4Lh

A = 2(4")(4") + 4(4")(6")    This is the numerical expression.

A = 128"     This is the numerical answer.

Part B

To see the difference between the 2 polyhedrons, I will place them as follows.

Pyramid Area = A = (4")(4") + 2(4")(6")

Prism Area = A = 2(4")(4") + 4(4")(6")

The numerical expression shows that the surface area of the prism has one more square area (as represented by 4"x4"), and has 2 more rectangular area (as represented by 4"x6").

The difference of the 2 numerical expressions can be found using subtraction:

A = [2(4")(4") + 4(4")(6")] - [(4")(4") + 2(4")(6")]

A = (4")(4") + 2(4")(6")

Hope this helps.

The option C. Driver's License is not necessary to book a flight.

Driver's License is an official document given to a person who is permitted to drive vehicle on the road.

This is usually given after certain tests including Physical driving and other general knowledge of driving.

Now, when we book a flight, credit card can be used to book a flight, but not necessary.

But there is a chance than you can use the credit card.

Arrival city is necessary when you book a flight because then only other procedures will follow.

Similarly, date of travel is also required in order to book the flight on a particular day.

So the least necessary document is Driver's License.

Hence Driver's License is not necessary to book a flight.

Answer:

alternate exterior angles= 1,7 and 2,8 corresponding, interior 3,6 and 4,5

Answer:

79

Step-by-step explanation:

So the angles in a quadraleteral add to 360

so put this in as an equation

4x-10 +x+62 + 2x+ 68 +3x +10= 360

10x+130=360

10x = 230

x=23

then work out each angle to find the smallest

x +62 = 85

2x+68 = 114

3x+10 = 79
