Step-by-step explanation:
Let e represent the number of students with blue eyes. Then the number of students with blond hair is 2e. The total number of students is ...
3 + e + 2e -6 = 30
We subtracted 6 because the expressions e and 2e cause the 6 students with both blond hair and blue eyes to be counted twice.
3e = 33 . . . . add 3 and simplify
e = 11
11 students have blue eyes.
Answer:
14 mi
Step-by-step explanation:
V = 718.38 mi³, r = 7 mi, find h
Use V = πr²h/3
718.38 = 3.14 * 7² * h/3
718.38 = 51.287 h
h = 718.38/51.287 = 14 mi
Answer: 175
Step-by-step explanation:
Let say
x the number of ticket at $6
y the number of ticket at $10
z the number of ticket at $12
500 total tickets were sold : x+y+z=500
the total income from ticket sales were $4.500: 6*x+10*y+12*z=4500
the combined number of $6 and $10 tickets was four times the
number of $12 tickets sold: x+y=4*z
x=175
