Answer: 51 notes span 6 octaves.
Step-by-step explanation:
The word "octave" is a Latin word that means "eight".
In an instrument, Each octave is made up of 8 musical notes.
If we have 51 notes , the number of octaves can be made in it =
Hence, 51 notes span 6 octaves.

Answer:
B. 5x−(−4x−6)=10
Step-by-step explanation:
The first equation gives an expression for y:
y = -4x -6
When that is used in the second equation, the result is ...
5x -y = 10
5x -(-4x -6) = 10 . . . . . . after substituting; matches B
Answer: 0.65
Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100. We can think of 65% as the ratio 65 to 100 or 65 divided by 100. Remember that dividing by 100 moves the decimal point 2 places to the left.
<h2>
65% → .65 or 0.65</h2><h2 /><h3>
Therefore, 65% can be written as the decimal 0.65.</h3>

If this ^ means exponents.
<span>Polynomials can be classified two different ways - by the number of terms and by their degree.
1. Number of terms.
<span><span>A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.</span>
<span>A binomial has two terms. For example: <span>5x2</span> -4x</span>
<span>A trinomial has three terms. For example: <span>3y2</span>+5y-2</span>
<span>Any polynomial with four or more terms is just called a polynomial. For example: <span>2y5</span><span>+ 7y3</span><span>- 5y2</span>+9y-2</span></span>
Practice classifying these polynomials by the number of terms:
1. 5y
<span>2. 3x2-3x+1 </span>
3. 5y-10
4. 8xy
<span>5. 3x4+x2-5x+9 </span>
Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial
2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).
Examples:
<span><span>5x2-2x+1 The highest exponent is the 2 so this is a <span>2nd degree</span> trinomial.</span>
<span>3x4+4x2The highest exponent is the 4 so this is a <span>4th degree</span> binomial.</span>
<span>8x-1 While it appears there is no exponent, the x has an understood exponent of 1; therefore, this is a <span>1st degree</span> binomial.</span>
<span>5 There is no variable at all. Therefore, this is a 0 degree monomial. It is 0 degree because x0=1. So technically, 5 could be written as 5x0.</span>
<span>3x2y5 Since both variables are part of the same term, we must add their exponents together to determine the degree. 2+5=7 so this is a <span>7th degree</span> monomial.</span></span>
Classify these polynomials by their degree.
