Answer 1

Answer:

Step-by-step explanation:

Bob: 8x

Josh: 4x

Ralph: x

8x + x = 180

9x = 180

X= 20

Josh:

X = 20

Multiply it by 4

X =80

Josh spent $80

Answer 2

The amount of money spent by Bob, Josh, and Ralph will be $160, $80, and $20.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

During a vacation together, Bob spent twice as much as Josh, who spent four times as much as Ralph.

Let x be the amount of money spent by Ralph.

Then Bob spent 8x and Josh spent 4x.

If Bob and Ralph together spent $180. Then the equation will be

8x + x = 180

     9x = 180

       x = 180 / 9

       x = $20

Then the money spent by Bob and Josh will be

Bob = 8x = 8 × 20 = $160

Josh = 4x = 4 × 20 = $80

Then the amount of money spent by Bob, Josh, and Ralph will be $160, $80, and $20.
