the other number is 50 - p
Consider a numeric example
2 numbers sum to 5 , one of the numbers is 3 what is the other ?
Obviously 2 , that is 5 - 3 = 2 gives the number
In the same way the number here is p and 50 - p is the other number
If the table is:
x | y
------
1 | 76
------
2 | 92
---------
3 | 108
-----------
4 | 124
-------------------------------------------------------------------------------------------------------------------
Find the change inbetween each amount per week
92 - 76 = 16
108 - 92 = 16
etc.
This means that her initial deposit should be subtracting 16 from her first deposit.
76 is the amount first deposited
76 - 16 = 60
A) $60 should be your answer
hope this helps
Well 3 less than 5 is 2 so we have 52 and 1 less than 2 is 1 so the answer is 152
Answer:
17,725/14.
Step-by-step explanation:
Let's say that the blank is represented by x.
Since the question asks what is 16.8% of x, we can set up a proportion where 16.8 out of 100 is equivalent to 212.7 out of x. The 100 represents the "whole" number, which corresponds to x. The 212.7 IS the 16.8 of x.
16.8 * x = 212.7 * 100
16.8x = 21,270
x = 21,270 / 16.8
x = 212,700 / 168
x = 17,725 / 14 = 1,266.071429
To check our work, 1,266.071429 * 0.168 = 212.7.
Hope this helps!
Answer:
(x + 1)(x - 1)(x² + 9)
Step-by-step explanation:
Factorise the following:
x⁴ + 8x² - 9
The factors of -9 that sum to 8 are 9 and -1.
So,
x²(x² + 9) - 1(x² + 9)
(x² - 1)(x² + 9)
x² - 1 = x² - 1²:
(x² - 1²)(x² + 9)
Factor the difference of two squares.
x² - 1² = (x + 1)(x - 1):
(x + 1)(x - 1)(x² + 9)
