Answer:
(-√(6-√26) < x < √(6-√26)) ∪ (x < -√(6 +√26)) ∪ (√(6 +√26) < x)
Step-by-step explanation:
Using x^2 = z, the equation can be rewritten as ...
z^2 -12z +10 > 0
(z -6)^2 -26 > 0
|z -6| > √26
This resolves to two equations.
This one ...
x^2 -6 < -√26 . . . . substitute x^2 for z
|x| < √(6-√26) . . . . add 6, take the square root; use √a^2 = |a|
-√(6-√26) < x < √(6-√26)
__
and this one ...
x^2 -6 > √26
|x| > √(6 +√26)
x < -√(6 +√26) ∪ √(6 +√26) < x
Answer
668 + 232 ones = 900
or
668 + 23 tens + 2 ones = 900
or
668 + 2 hundreds + 32 ones = 900
or
668 + 2 hundreds + 3 tens + 2 ones.
<u>Explanations</u>
900 - 668 = 232. Meaning we can add 232 ones to 668 to get 900.
232-200 = 32 ⇒ Meaning, we can add 2 hundreds and 32 ones to 668 to get 900.
32-30 = 2. This means we can add 2 hundreds, 3 tens and 2 ones to 668 to get 900.
900 - 668 = 232
Answer:
x=3
Step-by-step explanation:
Selling Price = $145
Charge on first $25 is 5.25%
5.25% of $25 =
Charge on rest is 3.25%
rest amount = $145 - $25 = $120
3.25% of $120 =
