I Have A Math Test Coming Up And This Geometry Stuff Is Just Always Confusing Me. With That Said If You

Answer 1

Answer:

a = 1

Step-by-step explanation:

Step 1: Write equation

a - 2(4 - a) = 7a - 12

Step 2: Solve for a

Distribute -2: a - 8 + 2a = 7a - 12

Combine like terms: 3a - 8 = 7a - 12

Subtract 3a on both sides: -8 = 4a - 12

Add 12 on both sides: 4 = 4a

Divide both sides by 4: a = 1

Step 3: Check

Plug in x to verify if it's a solution.

1 - 2(4 - 1) = 7(1) - 12

1 - 2(3) = 7 - 12

1 - 6 = -5

-5 = -5

Answer 2

Answer:

a = 1

Step-by-step explanation:

equation given:   a - 2(4 - a) = 7a - 12

distribute and expand the equation

a - 8 + 2a = 7a - 12

combine similar terms:

a + 2a - 7a = -12 + 8

simplify:

-4a = -4

a = -4 / -4

a = 1

proof that a = 1

a - 2(4 - a) = 7a - 12

1 - 2(4 - 1) = 7(1) - 12

1 - 2(3) = 7 - 12

1 - 6 = -5

-5 = -5  therefore, the a = 1 is correct.

If BD=7x-10, BC=4x-29,and CD=5x-9 what is x ?

Answers

From the question, we know that the sum of BC and CD equals BD.

BD = BC + CD = 7x - 10

BC = 4x - 29

CD = 5x - 9

Let's set BC and CD equal to BD

4x - 29 + 5x - 9 = 7x - 10

Combine like terms on the left side.

9x - 38 = 7x - 10

Add 38 to both sides and subtract 7x from both sides.

2x = 28

Divide both sides by 2

x = 14

Answer:

The result of the rotation is Ali the Alien having the same orientation before the rotation.

The center of rotation is the same as the center of Ali the Alien.

Let's take the center of Ali the Alien as the center of rotation, so when Ali the Alien is rotated through 180° we will discover that Ali the Alien will have the same orientation as he did before the rotation.


William just accepted a job at a new company where he will make an annual salary of
$60000. William was told that for each year he stays with the company, he will be
given a salary raise of $5000. How much would William make as a salary after 5
years working for the company? What would be his salary after t years?
Salary after 5 years:
Salary after t years:

Answers

Answer:

Salary after 5 years: 60000+(5000)5= 85000

Salary after T years: 6000+(5000)t

Step-by-step explanation:

The way that you would find the amount of money needed after 5 years is by multiplying the 5000, since that is William's raise per year, and then adding 60000, which is the original salary.

In order to find William's salary after t years, since you do not have a number, but have t, you would want to multiply 5000, which is the yearly raise, and t, hich can be any amount of years. After that, you would want to add William's original income to find an answer.

HELP Plssss..... The m

Answers

Answer:

Step-by-step explanation:

Hey there!!!

According to the question,

Angle P is three less than twice less of an angle Q.

Then, let angle Q be x then angle P is 2x-3.

Now, it has also given that they are supplementary angle.

We know that the sum of supplementary angle is 180°.

Therefore, x+ 2x - 3°=180°.

Or, 3x = 180°-3°

Or, x = 177°/3

Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.

2m - n =8 Solve for n

Answers

Answer:

[tex] \boxed{\sf n = 2m - 8} [/tex]

Step-by-step explanation:

Solve for n:

⇒2m - n = 8

Subtract 2 m from both sides:

⇒2m - 2m - n = 8 - 2m

2m - 2m = 0:

⇒-n = 8 - 2 m

Multiply both sides by -1:

⇒-n × (-1) = (8 - 2m) × (-1)

⇒n = 2m - 8

The required value of n is equal to n = 2m - 8.

An expression is given in the question ; i.e., 2m - n = 8.

We have to find the value of the 'n' .

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

As per the question ;

The given expression is 2m - n = 8.

Let's solve it to get the value of n.

The value of n can be find out , if we bring n to the left side of equal sign and 8 to the right of equal sign.

So ,

2m - n = 8 can be written as ;

2m = 8 + n

or

n = 2m - 8

Thus , the required value of n is equal to n = 2m - 8.

Solve 2(4x+2)=4x-12(x-1)

Answers

Answer:

x = 1/2

Step-by-step explanation:

Answer:

x = 0.5

Step-by-step explanation:

2(4x+2)=4x-12(x-1)   (by PEDMAS, we deal with the parentheses first by using the distributive property)

4x(2)+2(2)=4x+ x(-12) -1 (-12)

8x + 4 = 4x - 12x +12  (simplyfy each side)

8x + 4 = - 8x +12   (add 8x to both sides)

8x + 4 + 8x = 12

16x + 4 = 12    (subtract 4 from both sides)

16x = 12 - 4

16x = 8  (divide both sides by 16)

x = 8/16

x = 0.5
