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
Standard form: Ax + by =C
so
y+ 1 = 3/4(x - 16)
4(y + 1) = 3(x - 16)
4y + 4 = 3x - 48
3x - 4y = 52
Answer is D. last option
3x - 4y = 52
