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":

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

Find m<br> (-3x + 20)<br> (-2x + 55)

Sergeeva-Olga [200]

Answer: Solution for (-3x+20)+(-2x+55)=180 equation: x= -21

Step-by-step explanation:

Simplifying

(-3x + 20) + (-2x + 55) = 180

Reorder the terms:

(20 + -3x) + (-2x + 55) = 180

Remove parenthesis around (20 + -3x)

20 + -3x + (-2x + 55) = 180

Reorder the terms:

20 + -3x + (55 + -2x) = 180

Remove parenthesis around (55 + -2x)

20 + -3x + 55 + -2x = 180

Reorder the terms:

20 + 55 + -3x + -2x = 180

Combine like terms: 20 + 55 = 75

75 + -3x + -2x = 180

Combine like terms: -3x + -2x = -5x

75 + -5x = 180

Solving

75 + -5x = 180

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-75' to each side of the equation.

75 + -75 + -5x = 180 + -75

Combine like terms: 75 + -75 = 0

0 + -5x = 180 + -75

-5x = 180 + -75

Combine like terms: 180 + -75 = 105

-5x = 105

Divide each side by '-5'.

x = -21

Simplifying

x = -21
