explanation: 66.62 (bill) - 27.50 (monthly fee) = 39.12
39.12 is now the total of the charges for every minute he was on his phone. so we divide that number by the fee of .12 to find how many minutes he was on the phone, 326 minutes.
Answer:
10a²b² -8a²b +6ab² -4ab +7
Step-by-step explanation:
If P represents the given polynomial (sum), and A represents the unknown addend, it appears you have ...
A + (-5) = P
You want to find A. You can do that by adding 5 to both sides of this equation:
A = P +5
Adding 5 to the given polynomial gives you ...
10a²b² -8a²b +6ab² -4ab +7 . . . . the other addend
Answer:
Inherently asymmetrical casual relationship.
Step-by-step explanation:
The dog owners are given free dog food samples which contain new vegetables. These samples are given to them by organizing booths at the dog events. The reaction of the dog owners is observed towards this new dog food. This an example of inherently asymmetrical relationship.
Let
y----------> the length of the rectangle
x---------> the width of the rectangle
P--------> perimeter of a rectangle
we know that
P=38 ft
[P]=2*[x+y]------> 38=2*[x+y]------> equation 1
y=5+x-------> equation 2
<span>substitute 2 in 1
</span>P=2*[x+(5+x)]---------> P=4x+10---------> the given equation
4x=38-10--------> 4x=28----> x=7 ft
y=5+7-----> y=5+7------> y=12 ft
the answer is
the width is 7 ft
