Answer:
To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.
Answer:
I think it would be 4x
Step-by-step explanation:
Heres how. At first you ignore the exponent (you'll come back to it) 12x ÷ 6x = 2x. Then you have to solve with the exponent. 2 × 2 = 4 then add the label. 4x, and that's how you get the answer. Hope this helps.
The price before the discount was $81.00
Given;
Discounted price = $60.75
discount rate = 25%
Since the price is already discounted, it means that it is already 75% of the original price. So, we divided the discounted price by its corresponding percentage.
Original price - discount = discounted price
100% - 25% = 75%
$60.75 ÷ 75 % = $81.00
$81.00 * 25% = 20.25 discount
$81.00 - 20.25 = 60.75 discounted price
We are given the expression,
54x+81
Here we have to find Greatest Common Factor of 54 and 81
Factors of 54 are 1, 2, 3, 6, 9, 18 and 27.
Factors of 81 are 1, 3, 9, 27 and 81.
Greatest common factor of 54 and 81 is 27.
So we take out 27 common, rewriting the expression
27(2x+3)
Answer: 54x+81 in factored form equals 27(2x+3).
Answer:
The sequence is a function
Step-by-step explanation:
Given
Sequence:
; 
Required
Is the sequence a function
To determine if the sequence is a function or not, we start by calculating its range from the domain:
When n = 0; 
When n = 1: 
When n = 2; 
When n = 3; 
This implies that:
The domain (n) and the range (An) can be represented as:
![\left[\begin{array}{c}A_n&-&100&175&250&325\\-&-&-&\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7DA_n%26-%26100%26175%26250%26325%5C%5C-%26-%26-%26%5Cend%7Barray%7D%5Cright%5D)
<em>The above shows that the sequence is a one to one relation and a one to one relation is always a function.</em>
