<span>Amanda has 26 nickels and dimes.
We shall call nickels x and dimes y.
We can write the following equations:
x = 3y -2 or -x +3y = 2
x + y = 26
We can cancel out the x to give 4y = 28 or y = 7
If there are 26 coins in total and 7 of them are dimes then there must be 19 nickels.
The number of nickels (19) is two fewer than three times the number of dimes ( 3(7) - 2 = 19).</span>
To find perimeter you add up all the sides so the answer is 210
A human blinks 6,250,000 times a year.
A seal blinks 1,010 times a year.
The right answer is Option B: 
Step-by-step explanation:
Given,
Current value of car = $5500
This is 55% of the original value.
Let,
p be the original price of car.
Therefore,
55% of p = 5500

Dividing both sides by p

The equation
can be used to find the price Mrs. Merson paid for the car.
