Answer:
Step-by-step explanation:
Use the fact that sin 30 =0.5 and cos 30 = sqrt 3/2
we have answers as
8. u=16 and v = 
9) y=5 and x=
10) tan 30 =
So y=
x=
11) a=22 and b=11
12) b=1.5 and a=
13) y=
and x=10
Answer:
y-5x=21

answer
Sorry gurl but I don’t even understand my own algebra
Answer:
They each carried 25 books each.
Step-by-step explanation:
You get this by doing
84/5=16.8
then you do
84/2/5= 8.4
8.4+16.8=25.2
but round to whatever 5 or higher bump up below 5 keep the same
so your answer results in 25.
The LCM is the lowest number that is a multiple of all three numbers.
First, list the multiples of each number
8: 8, 16, 24, 32,40 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
10: 10, 20, 30 40, 50, 60, 70, 80, 90, 100, 110, 120
12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120
The LCM is 120 because there is no lower number that is a multiple of all three numbers.
Hope this helped!
