2y+12 < 42
subtract 12 from both sides to isolate the 'y'
2y<30
since '2y' is multiplication, the opposite is division. divide by 2 to isolate the 'y'. doing so will flip the < sign to make it >.
y > 15

She makes $15 an hour. Her employers take out $125 weekly. She gets a paycheck for $205 that week.
Add the $125 back in that her employer took out and you can find how much she earned that week, it's $330. Divide $330 by $15 to find that she worked a minimum of 22 hours that week.
15h-125=205
15h=330
h=22
plug 22 in to the equation 15h-125=205 to check your answer

I can't help you with the last one. Best of luck though man and god bless.
Step-by-step explanation:
The line is
j --------K----------M---------N---------L
6. 4. 4. 4
JN = 14
KM = 4
KM = MN = LN =4
JK = 14 - (KM+MN)
JK = 14 - 8 = 6
JK = 6
MN = 4
LJ = 18
KN = 8
MJ = 10
NL = 4
equivalent ratio's to 15:38
15 x 2 = 30
38 x 2 = 76
30:76 is equivalent to 15:38
15:38 x 3
15 x 3 = 45
38 x 3 = 114
45:114 is equivalent to 15:38
15:38 x 4
15 x 4 = 60
38 x 4 = 152
60:152 is equivalent to 15:38
The sum is 27 you just need to add them all together
