$11.\\2p+5r=q\ \ \ \ |subtract\ 5r\ from\ both\ sides\\\\2p=q-5r\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{p=\dfrac{q-5r}{2}}$

$17.\\\dfrac{2}{5}(z+1)=y\ \ \ \ |multiply\ both\ sides\ by\ \dfrac{5}{2}\\\\z+1=\dfrac{5}{2}y\ \ \ \ |subtract\ 1\ from\ both\ sides\\\\\boxed{z=\frac{5}{2}y-1}$

Jayden has $0.56 worth of pennies and nickels. He has a total of 20 pennies and nickels altogether. Determine the number of penn

Aneli [31]

Answer:

11 pennies and 9 nickels

Step-by-step explanation:

Set up a system of equations where p is the number of pennies and n is the number of nickels:

p + n = 20

0.01p + 0.05n = 0.56

Solve by substitution by rearranging the first equation:

p + n = 20

p = 20 - n

Then, plug this in as p into the second equation, and solve for n:

0.01p + 0.05n = 0.56

0.01(20 - n) + 0.05n = 0.56

0.2 - 0.01n + 0.05n = 0.56

0.2 + 0.04n = 0.56

0.04n = 0.36

n = 9

Then, plug this into the first equation to solve for p:

p + n = 20

p + 9 = 20

p = 11

So, Jayden has 11 pennies and 9 nickels
