Respuesta :

calculista

Answer:

Ryan volunteered 34 hours

Step-by-step explanation:

Let

x ----> the number of Ryan's hours

y ----> the number of Maddie's hours

we know that

[tex]x+y=45[/tex] -----> equation A

[tex]x=3y+1[/tex] ----> equation B

substitute equation B in equation A and solve for y

[tex]3y+1+y=45\\4y=45-1\\y=44/4\\y=11\ hours[/tex]

Find the value of x

[tex]x=3(11)+1\\x=34\ hours[/tex]

therefore

Ryan volunteered 34 hours
