Answer:
can post a picture of the question?
Recognize that both 0.96 and 0.144 are divisible by 12:
(0.96/12) / (0.144/12) = 0.08 / 0.012. This reduces to 0.02 / 0.003, or
20/3 or approx. 6.666.
You could also begin by eliminating the decimal fractions. Mult. 0.96 and 0.144 each by 1000 results in 960/144.
Since both 960 and 144 can be divided evenly by 24, we get 40 and 6.
40/6 = 20/3, or approx. 6.666, as before.
Answer:
4
Step-by-step explanation: because their 5 students and 5 times 4 equals 20
N^2-3n-4=0
(n-4)(n+1)
-4+1=-3
-4*1=-4
n-4=0
n=4
n+1=0
n=-1
Final answers: x=-1, x=4
