Answer:23
Step-by-step explanation:
X^2 + y^2 = 8
X-y=0 so x = y
replace x = y into X^2 + y^2 = 8
y^2 + y^2 = 8
2y^2 = 8
y^2 = 8/2
y^2 = 4
y = - 2 and y = 2
because x = y
so x = - 2 and x = 2
solutions:
x= - 2 and x = + 2
y= - 2 and y = + 2

you add up 138+225 and you get 363 then you subtract 482-363 this is how you set it up:
4 8 2
- 3 6 3
------------
you have to borrow because 3 does not go into 2 so you change the 8 into a 7 then you 10 to 2 and you get 12 so this is what it looks like:
4 7 12
- 3 6 3
-------------------
so you then subtract 12-3=9 then 7-6=1 then 4-3=1
so this is what it looks like
4 7 12
--- 3 6 3
--------------------
1 1 9
so on Sunday they rode 119 miles
