Ben has mixed up the digit for millions and hundred thousands: he wrote 5
in the place for millions and 6 in the place for hundred thousands, but
it should be the other way. I think that he should exchange those two digits in the faulty report.
Y = 12x where x is the # of students and y is the # of adults
Or for every 12 students there's 1 adult
Answer:
D
Step-by-step explanation:
a,c,d are same but b is different.
Y = -4x - 2
P (-16, -11)
a = -4, b = 0, c = -2
m = -a/b
m = -(-4)/(-2)
m = 4/(-2)
m = -2
y-yo = m(x-xo)
y-(-11) = -2[x-(-16)]
y+11 = -2(x+16)
y+11 = -2x-32
2x+y+11+32 = 0
2x+y+43 = 0

yes sure, i learned this before so
1. a. make a proportion here, of percentage. 
if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again, 
cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
