The absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry is, |x−30|=10. So, Option A is correct

An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.

For example, 3x+2y=0.

Types of equation

1. Linear Equation

2. Quadratic Equation

3. Cubic Equation

Given that,

On average, Jack can fold his laundry in 30 minutes

How much laundry he has, his time can vary from the average by 10 minutes

So, maximum time can be 40 minutes

And minimum time can be 20 minutes

Therefore, The result is  |x-30| =10

Current population = x

The population of a city is expected to decrease by 6% next year.

To find:

The expression that represents the expected population next year. ​

Solution:

We have,

Current population = x

Decrease rate = 6%.

Expected population next year = Current population - 6% of Current population

                                                    =[tex]x-\dfrac{6}{100}x[/tex]

                                                    =[tex]x-0.06x[/tex]

                                                    =[tex]0.94x[/tex]

Therefore, the expression for the expected population next year is 0.94x.

Answer:

V2 = 8571.43L

Step-by-step explanation:

To solve for the V2, We can use V2 = P1V1 / P2

= 1.0 atm × 12,000 L / 1.4 atm    

 = 12,000 L / 1.4 atm

= 8571.43 L

given data

The resort charges $20.75 per hour in addition to a $35 deposit to rent a snowboard

The time spent from 8:30 am to 12:30 pm = 4hours

Step two:

Let the number of hours be and the total cost be y

Now the expression for the situation can be represented as

He can build 3 toys in 4 minutes.

Step-by-step explanation:

Divide 360 by 8 since you are dividing it first to get the number of toys he can build in an hour.  As a result, he can build 45 toys in an hour.  Divide that number by 15 since 4 times that number equals an hour.  You should get 3 toys as your final result.  

For easier explanation, multiply 8 and 15 together to get 120 for better understanding.  Divide that number from 360 to get the same answer.
