You're looking for c, so you want to isolate it or get it by itself. To get rid of the /3 you multiply since the opposite of division is multiplication and to get rid of it, you do the opposite (like -9 you would add 9 to get it to 0). Now you are left with -19+c = 24 (the 24 is 8*3 because what you do to one side you do to the other. Now you get c by itself so you add 19 to both sides which leaves you with C= 43. Sorry if this was confusing!
Answer:96
Step-by-step explanation:
A; 480/16 = 30 students per classroom
B: 192/12 =16 students per classroom
we need x such that 
which means
(480-x )* 12 should be equal to (192+x) * 16
5,760 - 12x = 3,072+16x
5,760 - 3,072 = 12x + 16x
2,688 = 28x
x = 96
Answer:
<h2>31.25% or 1/16 of her test</h2>
Step-by-step explanation:
Step one:
given
let the total amount of her test be x
we are told that she complete 1/8x test in 2/5 of an hour
hence she completed 1/8x in 0.4 hours
let us find the rate at which she completes are test
rate= 1/8x/0.4
convert the numerator to decimal number for easy computation
rate= 0.125x/0.4
rate=0.3125x per hour
Step two:
Hence 1 hour she can finish 0.3125x *1
=0.3125x
She can finish 31.25 % of her test in 1 hour
or 1/16 of her test
