5. The system
Px + Qy =R
Fx + Gy = H
has the solution (3,-1), where F, G, H, P, Q,
and Rare nonzero real numbers.
Select all the systems that are also guaranteed to have the solution (3,-1).
A. (P + F)x + ( + G)y = R +H
Fx + Gy = H
B. ® (P + F)X + Qy = R+H
Fx + (G+Q)y = H
C. Px + Qy =R
(3P+F)X + (3Q +G)y = 3H+R
D. Px + QY = R
(F-2P)X + (G-20)y = H-2R
E. Px + Qy = R
5Fx + 5GY = 5H
1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
