60 / 2 = 30
30 * 5 = 150
he had $150 at first
60, the amount he was left with was 2/5 or 40% of his original amount
-11/12 +5/12 = - 6/12= - 1/2
X = -8.
subtract 19.
-X = 8
divide by -1.
X = -8
(-7x² + 3) + (4x² + 2x - 1)
-7x² + 3 + 4x² + 2x - 1
(-7x² + 4x²) + (3 - 1) + 2x collect like terms
-3x² + 2x + 2
hope this helps, God bless!
