xxTIMURxx [149]

Answer:

Joey has 18 nickles and 27 dimes in his piggy bank.

Step-by-step explanation:

1 nickle = 5 cents

1 dime = 10 cents

$1 = 100 cents

$3.15 = 135 cents

Let

n represent the number of nickles, n>=0

d represent the number of dimes, d>=0

Joey counted a total of 45 coins that added up to $3.15:

n + d = 45

5n + 10d = 315

n = 18 nickles

d = 27 dimes

PLZ HELP ME >>>>>>THANKYOU

Aleonysh [2.5K]

Step-by-step explanation:

There are two commonly recognized beginner methods to solve a system of equations. The first is elimination and the second is substitution. I will go over both of them here.

Substitution:

$y=-2x-9, y=-5x-21$

$-2x-9 = -5x -21$

$3x=-12$

$x=-4$

$y=-5(-4)-21$

$y=-1$

Elimination:

This method is a bit hard to explain without visual aid, but I'll try my best :)

In elimination you can subtract each value with a common variable from its counterpart in the other equation. For this example, subtract y-y to get 0, -2x - (-5x) to get 3x, and -9 - (-21) to get 12.

Thus,

$-12=3x$

$x=-4$

$y=-5(-4)-21$

$y=-1$

Hope it helps and lmk if you need more help <3 :D
