I did the elimination method and it said 4 nickels which in turn gives me 52 pennies.

Answers

There are 32 pennies and 24 nickels in jar

Solution:

Let "n" be the number of nickels

Let "p" be the number of pennies

1 penny = 0.01 dollar

1 nickel = 0.05 dollar

There are 56 coins in the jar in all

Therefore,

number of nickels + number of pennies = 56

n + p = 56 ----------- eqn 1

The total value of coins is $ 1.52

Thus we frame a equation as:

number of nickels x 0.05 + number of pennies x 0.01 = 1.52

$n * 0.05 + p * 0.01 = 1.52$

0.05n + 0.01p = 1.52 -------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

n = 56 - p ------ eqn 3

Substitute eqn 3 in eqn 2

0.05(56 - p) + 0.01p = 1.52

2.8 - 0.05p + 0.01p = 1.52

0.04p = 2.8 - 1.52

0.04p = 1.28

Divide both sides by 0.04

p = 32

Substitute p = 32 in eqn 3

n = 56 - 32

n = 24

Thus there are 32 pennies and 24 nickels in jar

16+5x=8x-5 What would the variable be?

Answers

16+5x =8x-5

Reorder the terms
16+5x = -5+8x
Solving for variable for x

Move all terms containing x to the left, all other terms to the right.
Add -8x to each side of the equation.
16+ -3x = -5 + 8x + -8x

Combine like terms: 5x + -8x=-3x
16+-3x = -5 + 8x + -8x

Combine like terms: 8x + -8x = 0
16+-3x = -5 + 0
16+ -3x = -5

Add -16 to each side of the equation
16+-16 + -3x = -5 + 16

Combine like terms: 16+ -16 = 0
0 + -3x =-5 + -16
-3x = -5 + -16

combine like terms: -5 + -16 = -21
-3x = -21
Divide each side by -3
x=7

Please help this is very easy!!!!!!!
