Find The Measure Of Angle A:find The Measure Of Angle B:

Answers

Answer 1

Answer:

Hi...

2x+4+2x-9+x=180

5x-5=180

5x=185

X=185/5=37....so

A=2*37-9=65

B=2*37-4=70

Answer 2

Answer: see explanation

Step-by-step explanation:

Sum of all angles in a triangle is 180

So add all those angles together equals 180.

2x + 4 + 2x -9 + x = 180

Combine like terms.

5x -5 = 180

5x = 185

X = 37

Now plug x in for the angles

A = 2x -9

A = 2(37) - 9

A= 74 - 9 = 65

B = 2x + 4

B = 2(37) + 4

B = 74 + 4

B = 78

How can you use inverse operations to solve equations with multiplication and division?

Tell how many terms the expression has 15.5 - (6x2)-(16 ÷ 4)

Answers

Answer:

There are three terms in the expression.

Step-by-step explanation:

Some background knowledge:

Algebraic expressions do not include equal signs.

Terms are generally values that are added or subtracted.

For example,

2x+6 has two terms which are 2x and 6.

Here:

The term 2x has a coefficient (the number next to a variable) of 2 and the term '6' is a constant.

Please note that a constant is a number that does not include a variable.

LET US SOLVE OUR CASE:

Given the expression

15.5 - (6 x 2) - (16 ÷ 4)

Please note that:

(6 x 2) is one term. Because of the parentheses, it groups it as one term.  (16 ÷ 4) is also one term. Because of the parentheses, it groups it as one term.  

Therefore, there are three terms in the expression.

Solve for x. 2(x-4)=17 a. X=1 b. X=2 c. X=12.5 d. X= 11

Answers

The answer is C.

Explanation: if you put 12.5 instead of x. 2(12.5-4)=17 and follow the order of operations you should get 17.

Answer:

c. x=12.5

Step-by-step explanation:

Equation Solving

Given the equation

2(x - 4) = 17

Solving for x implies doing several operations needed to have x isolated in the left part of the equation.

Dividing by 2:

x - 4 = 17/2

x - 4 = 8.5

Now we add 4:

x = 8.5 + 4

x = 12.5

Answer:  c. x=12.5

Answers

Answer:

$200 dollars my friend.

Step-by-step explanation:

Hope I helped!

The solution is Option G.

The value of the equation A = ( 2/3 ) x 15% x $ 2000 = $ 200

What is an Equation?

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 equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 2/3 ) x 15% x 2000   be equation (1)

On simplifying the equation , we get

A = ( 2/3 ) x ( 15/100 ) x 2000

A = ( 2/3 ) x ( 15 ) x ( 20 )

On further simplification , we get

A = ( 2/3 ) x 300

A = 2 x 100

A = $ 200

Therefore , the value of A is $ 200

Hence , the equation is A = $ 200

Answer:

(3,8): No,  (-1,-11): Yes,  (2,7): Yes,  (0,-6): No

Step-by-step explanation:

Basically, you just substitute x and y with the numbers given.

18x - 3y = 15

y = 6x - 5

(3,8):

18(3) - 3(8) = 15

54 - 24 = 30  It is not equal to 15, so it does not work.

y = 6x - 5

8 = 6(3) - 5

8 = 13  It is not equal to 8, so it does not work.

Therefore, (3,8) is not a solution.

Try this for every pair and you will find that (-1,-11) and (2,7) are solutions.

The exact value of cos 120° in simplest form with a rational  denominator.

We have,

[tex]\cos 120^\circ[/tex]

[tex]\cos 120^\circ=\cos (90^\circ+30^\circ)[/tex]

[tex]\cos 120^\circ=-\sin 30^\circ[/tex]             [tex][\because \cos (90^\circ-\theta)=-\sin \theta][/tex]

[tex]\cos 120^\circ=-\left(\dfrac{1}{2}\right)[/tex]             [tex][\because \sin 30^\circ=\dfrac{1}{2}][/tex]
