Answer:
Step-by-step explanation:
4x - 12 - 5x ≥ -1
-x - 12 ≥ -1
-x ≥ 11
x ≤ -11
In order to get your answer, take the number of text messages you send each day (12) and subtract it from the number you and your sister send (26). When you get the answer from subtracting both of these numbers, take the answer from your subtraction and add it to the number of text messages that you send a day (12).

Show that 
We start by writing out the given expression
Then, take nth root of both sides
For instance:
Let a = 2, b = 2 and n = 4
First
Since 
Then
Proved
<em>This is so for all positive values of a,b and n where a < b</em>
Answer:
(x-y)(x-y-1)
Step-by-step explanation:
1.(x - y)² - x + y = (x - y)² - (x - y )
2.(x-y) [( x-y) - ( 1 ) ]
3.(x-y)(x-y-1)
So n=number of nickles
d=number of dimes
n is 12 more than d so
n=12+d
but they have same amount of money so
n times 5=worth of nickles
d times 10=worth of dimes
5n=10d
divide both sides by 5
n=2d
subsitute
n=2d
n=12+d
2d=n=12+d
2d=12+d
subtract d from both sides
d=12
subsitute
n=12+d
n=12+12
n=24
24 nickles
12 dimes
