2x+79+32=180
2x+111=180
2x=69
x=34.5
Both equations have as the left hand side.
Then, in a situation like
we can deduce , since they both equal
So, we can set up the equation
The solutions are
From the second equation we know that y is one more than x, so we have
Answer:3.5 miles
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
6/0.3=20
So 32=(number of boxes) times (number of books per box)
number of books per box=8
number of boxes=n
32=n times 8
so equation is
32=8n
sol divide both sides by 8
32/8=8/8n
4=1n
4=n
4 boxes
