Write a power that has a value greater than 140 and less than 145.

Answers

Answer:

$12^(2)$

Step-by-step explanation:

To find: a power that has a value greater than 140 and less than 145

Solution:

Take $x=12^(2)$

Here,

$12^(2)=144$ and $140<144<145$

That is $140<x<145$

Therefore,

$12^(2)$ has a value greater than 140 and less than 145.

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

What is halfway between pi and 2pi?

Answers

We are asked to determine the number that is haflway between pi and 2 pi. to determine the number, we can separate pi and get whats between 1 and 2 (coefficients of pi). The midpoint is 1.5 which is equal to 3/2. Hence, adding pi, the final answer is 3pi/2.

Answer:

3π/2 is halfway between π and 2π.

Step-by-step explanation:

We have been asked to find the value that is halfway between π and 2π.

In other words, we have to find the mid value of π and 2π.

This is equal to the average of π and 2π.

Average of two numbers a and b is given by

$\text{Average}=(a+b)/(2)$

a = π, b = 2π

Hence, the average or mid value of the given numbers is

$\text{Mid value}=(\pi+2\pi)/(2)$

Simplifying, we get

$\text{Mid value}=(3\pi)/(2)$

Hence, 3π/2 is halfway between π and 2π.

Evaluate. −|a+b|/2−c when a=1 3/5 , b=−2 , and c=−7 as a simplified fraction
