Answer:

Ryan's maximum time to complete a puzzle is 5 hours

Ryan's minimum time to complete a puzzle is 1 hour

Step-by-step explanation:

The complete question is

On average, Ryan can finish a puzzle in 3 hours but, depending on the difficulty of the puzzle, his time can vary from the average by 2 hours.

Which absolute value equation can be used to calculate Ryan's maximum and minimum time to complete a puzzle?

Let x represent the maximum and minimum time

we know that

The absolute value of the difference between x and the average must be equal to 2

$\left|x-3\right|=2$

Solve the absolute value

First case (positive case)

$+(x-3)=2$

$x=2+3\\x=5$

Second case (negative case)

$-(x-3)=2$

Multiply by -1 both sides

$(x-3)=-2$

$x=-2+3\\x=1$

therefore

Ryan's maximum time to complete a puzzle is 5 hours

Ryan's minimum time to complete a puzzle is 1 hour

Turn it into a proper fraction or even a decimal number.

For instance 13/2 = 6 1/2 or 6.5 which you can see would be between 6 and 7.

Solve each equation for the variable. n + 3 = 8 4 + w = -8

Bezzdna [24]

1.) answer: 5
Steps subtract 3 from both sides 8-3 is 5 so x is 5

2.) answer: -12
Because the 4 is positive you subtract it on the other side to cancel it out and -4 +-8 is -12 so x is -12
