Answer:
m =(-7-√73)/2=-7.772
Step-by-step explanation:
30t + 20c =< 300
5t + 10c =< 110
10c =< 110-5t
30t + 220-10t =< 300
20t =< 80
t = 4
120c + 20c =< 300
20c = 180
c = 9
Answer:
A: Move the decimal one place to the left
Step-by-step explanation:
Examples:
20 / 10 = 2
2 / 10 = 0.2
0.2 / 10 = 0.02
0.02 / 10 = 0.002
We are given

We can write it as

we can see that 2y is in first two terms
and -8 is in last two terms
so, we can factor it out

now, we can see that x+4 is common in both terms
so, we can factor it out

we can see that
x+4 is one of factor of terms
so, option-B..........Answer
