Answer:
add 5 to both sides, divide by 2, take square root, subtract 3/4
Step-by-step explanation:
I think you maybe do the reverse order of operations, which is SADMEP (subtract/add, then divide/multiply, then take care of exponents and square roots, then do that same order for whatever's in parenthesis.)
Answer:
-0.2
Step-by-step explanation:
Sine and cosine are co-functions.
That means, cos(90-x)=sin(x) or sin(90-x)=cos(x).
So here since cos(90-x)=-0.2, then sin(x)=-0.2.
Is this question multiple choice or can you just write a random perfect square number? An example of one would be 25
1 over 1/2 will simplify into 2. 2/1 simplifies into 2. All we are doing is just dividing by 2 on both the denominator and numerator. So if we want the 1/2 into a whole number, just multiply it by 2 on both sides which then you get 2/1 which simplifies into 2. So the answer is 2. Hope this helps and answers your question!
