Shalu is 16 years old.

The equation can be defined as a mathematical term that refers to a situation in which several factors must be considered. It is defined as the state of being equal and is frequently represented as a math expression with equal numbers on either side.

Two expressions joined by an equal sign form a mathematical statement known as an equation.

Shalu's brother was born 2 years before Shalu.  

Shalu's sister was born 4 years after Shalu.  

And the sum of Shalu's brother and sister's age is 30 years. 

Let x be the age of Shalu.  

As Shalu's brother was born 2 years before her = x + 2

As Shalu's sister was born 4 years after her = x - 4.

Therefore,  

x + 2 + x - 4 = 30

2x - 2 = 30

Adding 2 on each side of the equation,

2x -2 + 2 = 30 + 2

2x = 32

Dividing each side of the equation by 2.

2x / 2 = 32 / 2

x = 16

Therefore, Shalu is 16 years old.

Answer:

40

Step-by-step explanation:

The number ribbons cut from the 5 feet long one is 40 ribbons, the equation is n = 5÷1/8

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

For example, 3x - 5 = 16 is an equation.

Given that, a ribbon of 5 feet long ribbon is cut into n 1/8-foot-long ribbons, we need to determine the equation calculates the number of 1/8 foot pieces,

So, the equation =

n = 5÷1/8

n = 40

Hence the number ribbons cut from the 5 feet long one is 40 ribbons, the equation is n = 5÷1/8

The value of given function is  f'(x)=4 e^sin(x)cos (x)

The derivative is what calculus is all about. The instantaneous pace at which a function changes with regard to one of its variables is known as the derivative. Finding the slope of the tangent line to the function at a given point is equal to doing this.

f'(x) =  d/dx ( 4 e^sin(x))

using differential rule d/dx (a x f ) = a x d/dx(f)

f'(x) = 4 x d/dx ( e ^ sin(x))

use the chain rule

f'(x)= 4 x d/dg ( e^g) x d/dx (sin (x))

f'(x)= 4 e^g x d/dx (sin (x))

f'(x)= 4 e^g x cos (x)

f'(x)=4 e^sin(x) x cos (x)

Answer: x=8

Step-by-step explanation:

4x+6y=50

4x+6(3)=50

4x+18=50

4x=32

x=8

The value of x when y = 3 in the linear function 4x + 6y = 50 is x = 8.

Use the concept of linear fucntion defined as:

The formula for a linear function is f(x) = mx + b, where m and b are real values. The slope-intercept form of a line is represented by the equation,

y = mx + b.

The given linear fucntion is:

4x+6y= 50

To find the value of x when y = 3,

Substitute y with 3 in the equation and solve for x.

4x + 6(3) = 50

4x + 18 = 50

To isolate x,

Subtract 18 from both sides:

4x = 50 - 18

4x = 32

Now we divide both sides by 4:

x = 32/4

x = 8

Hence,

When y = 3, the value of x in the linear function 4x + 6y = 50 is 8.

If the sum of a number and three is ​tripled the result is one less than twice the number. The number is 14.

Write an equation and expressions by defining variables first.

"a number" is x.

Then "the sum of a number and three is tripled" is 3(x+3).

And "five less than twice the number" is 2x - 5.

Set them equal and solve for x.

3(x+3) = 2x -5

3x+9 = 2x-5

x+9 = -5

x = -14

Let take "number" is x.

Then from given "the sum of a number x and 3 is tripled" is 3(x+3).

And "twice the number x  and less then 1" is 2x - 1.

Set them equal and solve for x.

3(x+3) = 2x -1
