<span>Let x=number of nickels in the piggy bank
(2x+3)=number of dimes in the piggy bank
(3x-3)=number of quarters in the piggy bank
.05x+.10(2x+3)+.25(3x-3)=14.55
.05x+.20x+.30+.75x-.75=14.55
</span>
<span>
1.00x=14.55+.45
x=15
2x+3=33
3x-3=42
The number of nickles in the piggy bank would be 15.

<span><span>The number of dimes in the piggy bank would be 33

<span>The number of quarters in the piggy bank would be 42. </span>
Hope I was able to help and that this was useful to you!!! :)
Answer: 135
Step-by-step explanation:
1.) You want to count the amount of sides (8)
2.) You then subtract 2 from the amount of sides (8-2)
3.) After you times that by 180 (6*180)
4.) You then take that number and divided it by you origanal amount of sides (1080/8)
5.) After that you get your answer (135)
Answer:
PEMDAS
Step-by-step explanation:
P - Parentheses (Brackets also!)
E - Exponents
M and D - Multiplication and division. Many people think multiplication has to be done first as said in "PEMDAS" but it doesn't. Do multiplication and division according to which ever one is farthest to the left (left to right).
A and S - Addition and subtraction. Same thing applies here, neither addition or subtraction has to be done first, just do them according to which one is farthest to the left when reading the expression from left to right.
Answer:
it's a square so all 4 sides of perimeter equal 12 while every inside line is 6 sqrt/2
Step-by-step explanation:
there's triangles in the square that are symmetrical so each triangle has the same sides so using pythagorean theorem 6sqrt/2 ^2 + 6sqrt/2 ^2 = sqrt/C and C=12
The answer is 9t because 9 times 6 is = 54
