<u>Answer</u>:
x = 3
<u>Step-by-step explanation</u>:
9x = 27
Divide both sides by 9,
x = 27/9 which on factorization of the numerator is written as
x = 9 x 3/9 = 3
Calculation 2: Exponent Or Index Method
9x = 27
Since 9 = 3² and 27 = 3³, the given equation takes the form
3² x = 3³
This gives
x = 3³ ÷ 3² = 3³¯² [using the formula a^m ÷ a^n = a^(m-n)]
= 3¹ = 3 (since the first power of a number is the number itself)
9 x 1 = 9
9 x 2 = 16
<h2>
9 x 3 = 27</h2>
9 x 4 = 36
We stop here because we have already got the answer 27, the right-side of the equality, when 9 is multiplied by 3 . So,
x = 3

The polynomials can´t contain:
-Variables in the exponents of the terms.
-Variables in the denominator.
- Negative exponents.
-Fractionals exponents.
-The variables cant be as radicals.
Therefore:
a) It is a polynomial (The variable is under a radical)
b) It is not a polynomial.
c) It is a polynomial.
d) It is not a polynomial. (It has a variable in the denominator).
e) It is a polynomial.
f) It is not a polynomial. <span> (It has a </span><span>variable in the denominator).</span>
Answer:
<h2><u><em>
2x = 84°</em></u></h2>
Step-by-step explanation:
the sum of the interior angles of a triangle is 180°
so
180 = 2x + x + 54
180 = 3x + 54
180 - 54 = 3x
126 = 3x
x = 126 : 3
x = 42°
------------------
2x = 42 * 2
2x = 84°
----------------
check
2x + x + 54 = 180
3x + 54 = 180
3 * 42 + 54 = 180
126 + 54 = 180
180 = 180

Answer:
4.5 feet, or is there is 5 feet as an option, then 5 feet.
Step-by-step explanation:
ya just subtract
Answer:
She would need to order 11.5 pizzas. But of course she wouldn't order 11.5 so she'll just round up and order 12 pizzas.
Step-by-step explanation:
Take 4 pieces of pizza for each person and multiply that by how many people there are in this case 23. The answer would be 92 pieces of pizza would be needed to feed all of the 23 people. So you take 92 and divide it by 4 because each person gets 4 slices and the answer you get is 11.5. If the question is a multiple choice and it gives you the option of 11.5 then that's the answer but if its a fill in then round up to 12 pizzas because if not there will not be enough pizza for everyone.
Hope this helped! :)
