$(x ^(-4) )^(5)$

Apply exponent rule :

$(a^b)^c = a^ ^(b.c)$

$=x ^((-4)*5)$

$(-4)*5$

$= - 20$

Apply exponent rule :

$a ^(-b) = (1)/(a^b)$

$= (1)/(x ^(20) )$

Solve the multi-step equation by combining like terms and using inverse operations and the properties of equality.Equation: –4x – 5 + 2x = –11

What is the value for x?

Answers

The value of x for the expression -4x - 5 + 2x = -11 is 3.

What is an equation?

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

Example:

-4x - 5 + 2x = -11 is an equation.

We have,

-4x - 5 + 2x = -11

Combine like terms.

-2x - 5 = -11

Add 5 on both sides.

-2x = -11 + 5

-2x = -6

Divide both sides by -2.

x = 3

Thus,

The value of x is 3.

Answer:

x = 3

Step-by-step explanation:

-4x - 5 + 2x = -11

add 5 to both sides and cancel the -5 on the left

-4x + 2x = -6

combine -4x and 2x

-2x = -6

divide both sides by -2 and cancel the -2 on the left

x = 3

Answers

Given:
diameter of two circles 3:5
small circle : 3
large circle : 5

circumference of two circles x : 113.1
small circle : ?
large circle : 113.1 m

3:5 = x :113.1
3*113.1 = 5*x
339.3 = 5x
339.3 / 5 = x
67.86 = x
