Ok so subtract 25 minutes from the overall time. Then divide 125 minutes by 50 to get 2.5. So your lamb weighed 2.5kilos
8, 10, 12
A helpful equation:
x+x+1+x+2 = 30
Combine like terms
3x + 3 = 30
Subtract 3 from each side
3x = 27
Divide each side by to isolate x
x = 9
x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.
The first number is 8. The best two even numbers after 8 are 10 and 12.
8 + 10 + 12 = 30, thus this is the sequence.
Her pay is 400 + .05x, where x is the amount of items she sold
400 + .05(1650) = $482.50
In standard from the X comes first, then your Y value, then your equal sign and your numbers that don't have a letter value. I'm having a bit of trouble reading your question tbh, but maybe that could help you?
