-5d – 16d + -14d + 8d – -13d = -14
-5d-16d-14d+8d+13d=-14
-21d-14d+8d+13d=-14
-35d+8d+13d=-14
-27d+13d=-14
-14d=-14
÷-14 both sides
d=1
Let
x---------> the total number of coins
we know that
512 cents-------> is equal to $5.12
1 penny is equal to $0.01
1 nickel is equal to 5 penny--------> $0.05
1 dime is equal to 2 nickel--------> $0.10
![\frac{x}{3}*[0.01+0.05+0.1]=5.12 \\\\x*[0.16]=15.36 \\\\ x=\frac{15.36}{0.16} \\\\x= 96\ coins](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B3%7D%2A%5B0.01%2B0.05%2B0.1%5D%3D5.12%20%5C%5C%5C%5Cx%2A%5B0.16%5D%3D15.36%20%5C%5C%5C%5C%20x%3D%5Cfrac%7B15.36%7D%7B0.16%7D%20%5C%5C%5C%5Cx%3D%2096%5C%20coins)
the total number of coins are 96
Divide 96 by 3 to obtain the number of coins of each type
therefore
<u>the answer is</u>
the number of penny coins are 
the number of nickel coins are
the number of dimes coins are

The greatest common factor and factoring by grouping of the following is;
- 3m
- 2a
- 8xy
- 5mn
- 3(r + t)²
- z²(m + n)⁴
<h3>Greatest common factor</h3>
The greatest common factor is the largest positive integer or polynomial that is a divisor of several different numbers. For instance, the greatest common divisor of 66, 30 and 18 is 6.
9m³, 3m², 15m
= 3m
4a², 6a, 2a³
= 2a
16xy³, 24x²y², 8x²y
= 8xy
10m²n², 25mn³, 50m²n
= 5mn
6m(r + t)², 3p(r + t)⁴
= 3(r + t)²
7z²(m + n)⁴, 9z³(m + n)^5
= z²(m + n)⁴
