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:

10+x+2x=70

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

d=\sqrt{[-9-0]^2+[-12-(-11)]^2}
\\\\\\
d=\sqrt{(-9-0)^2+(-12+11)^2}

d=\sqrt{(-9)^2+(-1)^2}\implies d=\sqrt{82}

Which sentence best describes the independent and dependent variables in the following problem? The parking garage charges $3 fo
alexandr402 [8]
Ok so the dependent variable would be $1.45 for each addition hour. The cost depends on every hour so u can't really calculate it unless u have the hours.
$3 is independent since it's only charged on the first hour. It doesn't rely on any other information.
