How many cubic feet are in a carton measuring 6 feet, 8 inches by 3 yards by 4.5 inches?
We can simplify it a bit
oh wait,
remember taht x^0=1, no matter what x is
we see the whole thing is to the zero power
the whole thing is equal to 1
doesn't matter what x or y is
the whole thing evaluates to 1
Answer:
The subtraction property of equality
Option A is correct
Explanation:
The given equation is:
12 - x = 7x + 32
Subtract 12 from both sides
12 - 12 - x = 7x + 32 - 12
-x = 7x + 20 (Step 1)
From step 1 above, subtract 7x from both sides
-x - 7x = 7x - 7x + 20
-8x = 20 (Step 2)
Since we subtracted 7x from both sides to get step 2, the justification for step 2 is the subtraction property of equality
All you have to do is divide 7 by 8 (so 7/8) and you get the answer: 0.875! hope that helps! :)
