X=3, y=5
Step-by-step explanation:
3x + y = 14 equation 1
y=5 equation 2
3x + 5 = 14. substitute value of y from equation 2 into equation 1
3x=9
x-3
10.65 is bigger because 65 is larger than 56
Total number of cans = N
number of weeks = w
The multiplier is 6.
Therefore the expression must be:
N = 6w
