Maria's book is longer than Brandon's. The difference in the two book lengths is 56
Bingel [31]

Answer:

Maria's book is 202 pages long, Brandon's book is 146 pages long

Step-by-step explanation:

We can set this up with 2 variables: lets say that Maria's book length is x and Brandon's is y.

We can see that Maria's book is 56 pages longer than Brandon's and can come up with an equation:

x=y+56

We also see that their booklengths add up to 348, and can get:

x+y=348

From here, we solve for x and y. We can use substitution to find y.

x+y=348

(y+56)+y=348

2y=292

y=146

Here we plug in for x:

x=y+56

x=(146)+56

x=202

Therefor we get that Maria's book is 202 pages long, Brandon's book is 146 pages long

1 1/8 +5/6 =<br><br> And then subtract 1/2 from the answer
kari74 [83]
Alright so start of with solving 1 1/8+5/6

Solve and you get 1 23/24

Now to subtract you have your answer subtracted by 1/2:

1 23/24-1/2=1 11/24

And so you get 1 11/24
