Answer:
she will spend 10 hours in class 40 hours studying and 20 hours working
Step-by-step explanation:
if u simply start at 1 hour of class u get to see the pattern example:
class. study. work
1 4. 2
she works twice as long as she is in class and studies 4 times longer than in class so for every hour she is in class do the math for this condition. for every class hour multiply by 4 to get her study time and then multiply her class hour by 2 to get her work hours. keep going until the total time of all activities adds to 70
F(x) = 2(x + 3), now if we distribute the 2, we get 2x + 6.
we know the lbs of apple is "x", and therefore, the lbs of orange will be the constant 3.
2x will then stand for the price for "x" lbs of apples.
and 2*3 will stand for the price of "3" lbs of oranges, which is 6 bucks.
since the 2 is multiplying the lbs quantity, it must then be the price, so both cost 2 bucks each per pound.
