Jack is growing Red wiggler worms to help make compost. He measured the lengths of two young worms. The 10- day old worm is 10/1
Lilit [14]

Answer:

The 20-day old worm is \frac{5}{6} inches more longer than the 10-day old worm.

Step-by-step explanation:

Jack is growing Red wiggler worms to help make compost. He measured the lengths of two young worms. The 10- day old worm is \frac{10}{12} inch long. The 20-day old worm is 1\frac{4}{6} inches long.  

Therefore, the 10-day old worm is \frac{10}{12} i.e \frac{5}{6} inches long.

And the 20-day old worm is 1\frac{4}{6} i.e. \frac{10}{6} = \frac{5}{3} inches long

Therefore, the 20-day old worm is (\frac{5}{3} - \frac{5}{6}) = \frac{5}{6} inches more longer than the 10-day old worm. (Answer)

dolphi86 [110]

Answer:

for the first question b,


it doesn't make sense for choice a to have -2 people in the car. You can't have a negative amount of people. For choice choice c, you can't have half a person, and for choice d, Ms. Valdez can only have under 5 people, not five people exactly.


for the second question I need to see the whole inequality, generally there is a variable, and all i see is <-1, which is invalid.


hope this helps, if it does like it pls!!
