Answer:
280 Day
Step-by-step explanation:
The longest 20% of pregnancies last at least 280 days.
The answer is: width = t - 9
A = l * w
A = t² - 4t - 45
l = t + 5
t² - 4t - 45 = (t + 5)w
Answer:
x*$10 + y*$16 = $480
Step-by-step explanation:
The question seems incomplete, and after a search online I've found a lot of similar questions with similar numbers, so I really can not be sure of which one is the complete question.
I suppose that we want to get a linear equation that describes the given situation:
Let's define two variables:
x = number of hours that Maggie works in the office (for $10 each)
y = number of hours that Maggie works driving a tractor (for $16 each).
Then the total amount of money that Maggie gets is:
x*$10 + y*$16
Now we know that she earns $480 per week, then we know that:
x*$10 + y*$16 = $480
This is a linear equation we wanted to get, where (just to be complete) we need to add the restrictions:
x ≥ 0
y ≥ 0
(this means that she can not work a negative number of hours).
