Construction.
When construction workers need measurements that are fractions they need to be able to multiply/add/subtract/divide all of those different fractions and mixed numbers.
I hope I was able to help. Best of luck.
-10a+15b + 15b-10a = -20a+30b
Have them right the slope formula down on a note card and make them use that formula until they can remember it.
One equation is...
-
12.99 + (0.6)x = 15.39
Answer:
Simplifying
(2x2 + -3x + 1)(x + -2)
Reorder the terms:
(1 + -3x + 2x2)(x + -2)
Reorder the terms:
(1 + -3x + 2x2)(-2 + x)
Multiply (1 + -3x + 2x2) * (-2 + x)
(1(-2 + x) + -3x * (-2 + x) + 2x2 * (-2 + x))
((-2 * 1 + x * 1) + -3x * (-2 + x) + 2x2 * (-2 + x))
((-2 + 1x) + -3x * (-2 + x) + 2x2 * (-2 + x))
(-2 + 1x + (-2 * -3x + x * -3x) + 2x2 * (-2 + x))
(-2 + 1x + (6x + -3x2) + 2x2 * (-2 + x))
(-2 + 1x + 6x + -3x2 + (-2 * 2x2 + x * 2x2))
(-2 + 1x + 6x + -3x2 + (-4x2 + 2x3))
Combine like terms: 1x + 6x = 7x
(-2 + 7x + -3x2 + -4x2 + 2x3)
Combine like terms: -3x2 + -4x2 = -7x2
(-2 + 7x + -7x2 + 2x3)
