Answer:

x = 24

Step-by-step explanation:

Simplify

( 3 x +10 ) − ( 2 x − 9 )

Simplify each term.

Apply the distributive property.

3 x + 10 − ( 2 x)− = 43

Multiply 2 by − 1 .

3 x + 10 − 2 x − − 9 = 43

Multiply − 1 by − 9 .

3 x + 10 − 2 x + 9 = 43

Simplify by adding terms.

Subtract 2 x from 3 x .

x + 10 + 9 = 43

Add 10 and 9 .

x + 19 = 43

Move all terms not containing x to the right side of the equation.

Subtract 19 from both sides of the equation.

x = 43 − 19

Subtract 19 from 43 .

x = 24

Answer: X = 24

Step-by-step explanation:

Move all terms to the left:

(3x + 10) - (2x - 9) - 43 = 0

Get rid of all the parenthesis:

3x + 10 - 2x - 9 - 43 = 0

Add all the numbers and all variable:

x-24 = 0

Move all terms containing x to the left and all other terms to the right:

x = 24

If a and b are two angles in standard position in Quadrant I, find cos(a+b) for the given function values. sin a=4/5 and cos b=5

vladimir1956 [14]

First let's find the angles a and b.

We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.

cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.

We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.

Find the ratio of 4 meter to 50 centimetre

ladessa [460]

(4 meters) / (50 centimeters)

= (4 x 100 centimeters) / (50 centimeters)

= (400 centimeters) / (50 centimeters)

= (400) / (50)

= 8 .

Identify the sequence as arithmetic, geometric, both, or neither. 50, –50, 50, –50, . . . both arithmetic geometric neither desc

stellarik [79]

Answer:

The sequence is geometric.

Step-by-step explanation:

In Arithmetic sequence, there is a common difference between any two consecutive terms but in Geometric sequence, there is a common ratio between any two consecutive terms.

Given sequence is: 50, -50, 50, -50,.................

Lets assume, the terms as $a_{1}, a_{2}, a_{3}, a_{4},...........$

Checking for common difference:

$a_{2}-a_{1}= (-50)-(50)= -100\\ \\ a_{3}-a_{2}=(50)-(-50)=100\\ \\ a_{4}-a_{3}=(-50)-(50)=-100$

As there is no common difference, so it's not an arithmetic sequence.

Checking for common ratio

$\frac{a_{2}}{a_{1}}=\frac{-50}{50}=-1\\ \\ \frac{a_{3}}{a_{2}}=\frac{50}{-50}=-1\\ \\ \frac{a_{4}}{a_{3}}=\frac{-50}{50}=-1$

As there is a common ratio, so it's a geometric sequence.
