Step-by-step explanation:
x- red candy
y- blue candy
x + y = 11
1.29x + .79y = 11.19
129x +79y = 1119
-129x -129y = -1419
-50y = -300
y = 6 lbs. blue
x + 6 = 11
x = 5 lbs. red
I think it might be B
because from 9+1 = 10 we can change to 9=10-1
and 10+6=16 no need to change
then we solve the problem with the equation
16 - 9
10+6 - (10-1)
10+6-10+1
7
thats the answer
1 kilogram : 1000 grams
7.32 kilograms : 1000 * 7.32 grams
7.32 kilograms : 7320 grams
