I plugged this into photo math, but apparently I have to pay to find out how to get the answer. can you guys help me out?

dimulka [17.4K]

Photo math is charging? We don't need it. We factor the difference of two squares.

$\dfrac{5t^2-500}{t+10} = \dfrac{5(t^2- 100)}{t+10} = \dfrac{5(t-10)(t+10)}{t+10} = 5(t-10) = 5t-50$

Answer: 5t-50

at the start of the shift your part counter reads 250 at the end of the shift the part counter reads 1075 how many parts did you

Luden [163]

This can be mathematically expressed to
250 + X = 1075
where X represents the parts you produce before the shift ends
Transpose 250 to the other side by subtracting each side by 250
Thus, it goes like this
X = 1075 - 250
X = 825

You produced 825 parts in the middle of the shift.
