The equation for this should be 4n - 15
There are 3 egg rolls divide evenly to 8 sisters
for 1 egg roll each sister would receive 1/8 since there are 3 egg rolls
multiply 1/8 x 3
each sister will get 3/8 of an egg roll
hope this helps
Answer:
-11m
Step-by-step explanation:
subtract the expression
Convert 3 hours and 30 minutes all into minutes so that would be 210 minutes. You then have 169 miles / 210 minutes. Get the denominator to 1 minutes by dividing by 210 to the top and bottom and you'll get .080476 miles / 1 minute which is the answer.
I'm going to assume you've learn sin, cos, and tan. To find a you must do:
Once you find a, you can use the Pythagorean Theorem to find b:
Or you can do:
You can find these functions on a scientific calculator. Let me now if you need more help.
