12 (don't take my answer because it's been awhile since I've fine a question like that but I'm pretty sure it's 12)
Simply add the hours worked together to find the total, so 4.5+8.75+9.5+10+4.25= your answer.
Step-by-step explanation:
y2+4y+1=0. where, y=-2
(-2)2+4(-2)+1
-4-8+1=0
-12+1=0
-11=0
okay,here is about a formula.
n=2x
where x is the numbers.
n=2×3
n=6.
therefore the three digit numbers which can be obtained is 6.
