Trish is taking care of the hans family dogs. the hans leave 7 cans of dog food for the 3 days theyll be away . how many more cans of dog food would trish need if she needed to feed the dogs 3 cans a day.

If the Hans leave for 3 days, and Tish wants to feed the dogs 3 cans each day, we can solve this problem using simple multiplication.

3 days * 3 cans / 1 day = 9 cans

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
