Answer:
315
Step-by-step explanation:
-3ac7
-3x-3=9x5=45x7=315
(3.10/3.35)-1*-1=0.07462686567
So the percantage decrease to the nearest tenth is 7.4%
3.35 x 0.07462686567= .25

Answer:
2u-1/3v = (4, -2)
Step-by-step explanation:
Given vector u and v,
v = (-6, -6)
u = (1, -2)
2*u = (2*1, -2*2) = (2, -4)
1/3*v = (1/3*-6, 1/3*-6) = (-2, -2)
So, 2u = (2, -4) and 1/3*v = (-2, -2)
We have 2u-1/3v = (2, -4) - (-2, -2) = (4, -2)
Therefore, 2u-1/3v = (4, -2)
