Answer:
20/7 days (just less than 3 days)
Step-by-step explanation:
Recall that (1 job) = (rate)(time), so time = (1 job) / (rate).
Set up and solve the following equation:
1 job
------------------------------- = time required for 2 pumps working together
1 job 1 job
---------- + -------------
4 days 10 days
This comes out to:
1 job
------------------------------------------- = time required
10 job-days 4 job-days
------------------ + -----------------
40 days 40 days
or:
1 job
-------------------- = (40/14) days, or 20/7 days (just less than 3 days)
14 job·days
-----------------
40 days
Answer:
c + ab
Step-by-step explanation:
The way an expression is written is the given you have presented to us.
The commutative law of addition would turn it around as
c + ab.
It just means change the order when adding. Not all systems allow this. It matters which way you put it in some systems.
Foil the equation; j*k, j*-5, 7*k, 7*-5, once you foil add like terms.
jk - 5j +7k - 35 is the final answer
Answer:
You just add them together. Sense your mixing yellow and blue there's more blue then there is yellow but anyway you would add the blue 2.0 since it's just two cups and add 0.5 sense it just this amount of yellow together and you get 2.5 because combined together this is the total amount.
