Answer:
a) 
b) 1.5 hours after thickness will be 2 inches.
Step-by-step explanation:

So, we'll say Mia gets $4.50 a day, since a standard weekend is two days, therefore adding up to $9 a weekend. So if Mia were to do her chores for 4 weekends, she'd have a total of $36 but not $40. So if she were to work an extra weekend, so 5 weekends, she'd have a total of $45. So you can say 5 weekends in order to earn more than $40.
Answer:
y=4
Step-by-step explanation:
4y + 3 =19
4y = 16
y= 4
You would be right with 26 because the absolute value of -30 is 30 then you subtract 56-30 and get 26 which is the remaining temp you need to get to 56.
