Distributive property was the first property used in STEP 1, where -4 was distributed to -3x+ 2 resulting in the equation in STEP 1. Next in STEP 2, commutative property of addition no matter how 12x and 6x are arranged, when you add them together the result will be the same.
*Take note that 12x and 6x are put together because they are like terms.
For Steps 3 and 4, you will see that the addition property of equality was used in STEP 3. To keep the equation equal, you will add the same number on both sides.
STEP 4 uses Division property of Equality. Like Step 3, to keep both sides of the equation equal, you must divide both sides with the same number. It keeps the statement true by doing so.
STEP 4 and 5 uses transitive property if you examine both as a whole.
Transitive property assumes that if a = b and b = c, then a = c
If 18/18 (a) = 1 (b), and x (c) = 18/18(a) then, x (c) = 1 (b).
Question 1. I am assuming you meant 9/16, and in that case, the answer would be 0.5625. 9-16 is -7.
Question 2. 35.7% in decimal form is relative to what the percent is of. 35.7% of a million is different than 35.7% of one.
Question 3. Once again, this is relative as to what. Percentage of the weight of an elephant? It is important to specify in these types of equations.
The answer would be 266400. If you would convert hrs into seconds.
The answer is D:216:1 good luck with apex
