Step-by-step explanation:
a =45°
b=45°
c=30°
d=30°
e=30°
f=30°
total of the angle
90×4=360
Lucas equation for his location is x(t) = 13t.
Alfonso's equation is x(t) = 238 - 21t
If you equate these, you get:
13t = 238 - 21t =>
34t = 238
t = 7
So after seven hours they meet.
8.5 is the same as 8.50, right? So just take the digit in the hundredth place of both decimals and subtract. You'd be doing 0-4 so you can go ahead and borrow a number to make 10-4, which equals 6. So without subtracting 8.5 and 4.64, you can determine that 6 will be in the hundredth place. Hope this helps!
Answer:
1. y=5-2x
2. -y=5-2x
3. 
Step-by-step explanation:
1. 2x+y=5
y=5-2x
2. 2x-y=5
-y=5-2x
3. x+2y=5
2y=5-x
