12%=(3+10%*x)/(20+x)
x=30
add 30 pounds of the second alloy
Answer:
e=30
k=15/2
h=90
Step-by-step explanation:
3e=60
e=30
30+4k=60
4k=30
k=15/2
15/2+2h=30
2h=45/2
h=90
Answer:
The answer is 2.
Step-by-step explanation:
1- Suppose we have following array of ten integers: 5 3 8 9 1 7 0 2 6 4.
2- Before the last merge, the left half and the right half must be sorted. So it should be
1 3 5 8 9 0 2 4 6 7
Therefore the solution is 2.
The other one is 90 minus 49 or 41 degrees
I am not sure but I think the answer is B.
