Answer 3 3/14
(7/8) times (45/14)= 45/16. Got 45/16 from 2 13/16
U . v = |u| . |v| cos 60 = 10 * 8 * 0.5 = 40 This is called the scalar (or dot) product.
4.) 2(x-1)+3= 2x+1
Distribute the 2, multiply the 2 by x and -1.
2*x= 2x (all you need to do is put 2 in front of x)
2*-1= -2
2x-2+3= 2x+1
Combine like terms.
2x+1=2x+1
Subtract one on both sides.
2x=2x
Divide by 2 into both sides.
x=1
We can check this by plugging it in.
2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works
I hope this helps!

The last one because it starts at -2 and is going back 6 places
