0.03x + 15 y = 0.03x - 15 y = -0.03x + 15 y = -0.03x - 15
First off, turn 7 1/4 into a mixed number, 29/4. change 29/4 / 5/6 into a multiplication question by flipping 5/6 into 6/5 (AKA multiplying by the reciprocal) so you get 29/4 X 6/5. then multiply so you get 174/20. Next, simplify into a mixed number by seeing how many times 20 goes into 174, and then putting the leftovers into a fraction, so you get 8 14/20, then simplify even further so you get 8 7/10.
(x - 5)^2 =
(x - 5)(x - 5) =
x^2 - 5x - 5x + 25 =
x^2 - 10x + 25 <===
The value of 5 is 50 because its in the tens place the value of 8 is 8 because its in the ones place.
