The numbers of quarters, dimes and nickels that were deposited are 5, 9 and 12 respectively.
He deposited $2.75 in nickels , dimes and quarter in his piggy bank.
let
number of quarter = x
number of dimes = x + 4
number of nickels = x + 7
1 dimes = $0.1
1 nickels = $0.05
1 quarter = $0.25
The total money he had in dollars is $2.75. Therefore,
- 2.75 = 0.25x + (x + 4)0.1 + 0.05(x + 7)
Therefore,
2.75 = 0.25x + 0.1x + 0.4 + 0.05x + 0.35
2.75 - 0.4 - 0.35 = 0.25x + 0.1x + 0.05x
2 = 0.4x
x = 2 / 4
x = 5
Therefore,
number of quarters = 5
number of dimes = 5 + 4 = 9
number of quarters = 5 + 7 = 12

Answer:
After arranging the terms of given Polynomial from highest to lowest the Polynomial becomes .
Step-by-step explanation:
Given:
We need to arrange the terms of given Polynomial from highest to lowest.
Now on seeing the above polynomial we can say;
The terms of polynomial can be arrange according to the highest number of exponent.
Form above expression we can say the first highest exponent term is
Hence the First term is .
Now we can see the second highest exponent term is
hence the second term would be .
now we can see the third highest exponent term is
hence the third term would be .
now we can see the fourth term is
hence the fourth term would be .
Hence After arranging the terms of given Polynomial from highest to lowest the Polynomial becomes
Order of operations is PEMDAS (parentheses, exponents, multiplication, division, addition, subtraction)
= (52 + 6) - (7 * 4) + 8
work inside parentheses first
= 58 - 28 + 8
work left to right now
= 30 + 8
= 38
SONYA'S MISTAKE
= (52 + 6) - (7 * 4) + 8
I think she added the 52, 6+4, multiplied 7*4 to equal 28, then added the 6+8 to equal 14
= 52 + 28 + 14 + 10
= 104
