In Step 6, the equation is ...
-12 = x - 36
In step 7, the equation is ...
-12 +36 = x -36 +36
Clearly, to get to step 7, 36 has been added to both sides of the equation.
Adding 36 to both sides of the equation is justified by ...
... C) Addition Property of Equality
_____
<em>More about the addition property of equality</em>
The addition property of equality says you can add the same value to both sides of an equation without changing the values of the variables that make the equation true. Here, x=24 makes the equation of step 6 true, and x=24 makes the equation of step 7 true.
Answer:
hertz (Hz)
Explanation:
The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.
Answer:
1/169
Step-by-step explanation:
There are 4 aces in a deck of 52.
The probability that the first card is an ace is 4/52.
Since the card is replaced, the probability that the second card is an ace is also 4/52.
The total probability is (4/52) (4/52) = 1/169.
I would go with C
Ecology is the study of interaction and relation between organisms and their environment as well as how organisms interact with each other
Remember that cosine is adjacent/hypotenuse. We can plug in the values given for this triangle.
Cos(A) = 5/13.
Don’t use a decimal answer as rounding would be necessary, and therefore you wouldn’t be giving an exact value. Leave your answer as 5/13.
