Jason has $0.37 worth of pennies and nickels. He has a total of 13 pennies and nickels altogether. Determine the number of penni
fredd [130]

Answer: Jason has 7 pennies and 6 nickels.

Step-by-step explanation:

Let be "p" the number of pennies that Jason has and "n"  the number of nickels that Jason has.

Set up a system of equations:

\left \{ {p+n=13} \atop {0.01p+0.05n=0.37}} \right.

You can use the Elimination Method. Multiply the first equation by -0.01 and add both equations:

\left \{ {-0.01p-0.01n=-0.13} \atop {0.01p+0.05n=0.37 }} \right.\\................................\\0.04n=0.24\\\\n=6

Susbtitute this value into the first equation and solve for "p":

p+6=13\\\\p=13-6\\\\p=7

How would solve for 2x – 17y = 13 for y
Andrews [41]

2x - 17y = 13

Since we don't have the the value of x we would set x = 0

2(0) - 17y = 13

And solve

-17y = 13

y = -13/17

You would do the same if you're solving for x

2x - 17(0) = 13

2x = 13

x = 13/2

(I'm not sure if you are missing anything but based on the information provided this is how I would solve it.)
