Together, Tim and Tom have $2.40. Tim has three times as much as Tom. How much does each have?

Phoenix [80]

X = how much Tim has

Substitute 3y for x
3y + y = 2.40

Plug in y value into previous equation
x = 3(0.60)
x = 1.80

Nostrana [21]

Answer:

The man traveled 20km by train.

Step-by-step explanation:

If x is the distance he traveled by train, you can write this equation to represent the situation:

Then, you can simply solve for x:

$10+3x=70\\3x=60\\x=20$

The man traveled 20km by train.

$10+(20)+2(20)=70\\10+20+40=70\\70=70$
