Cory is hiking up a hill with a constant slope the double number line shows that after Cory hikes 3 km his elevation is 120 m

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
