b
g(x) = – 1/3 |x + 5| + 2

c
h(x) = 1/3 |x + 5| + 2

d
r(x) = 5 |x + 3| – 2

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =
