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
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

The equation represents the pages after x nights.
Wren:
12 + 4x
Jenni:
4 + 5x
After 8 nights Wren and Jenni will be on the samepage of the book.
What is an equation?
An equation is a mathematical statement that is made up of two expressions connected by an equalsign.
We have,
Wren and Jenni are reading the same book.
Wren is on page 12 and reads 4 pages every night.
This can be written as an equation.
12 + 4x _____(1)
x = number of nights.
Jenni is on page 4 and reads 5 pages every night.
This can be written as an equation.
4 + 5x _______(2)
x = number of nights.
The number of nights after which both of them will be on the samepage.
From (1) and (2) we get,
12 + 4x = 4 + 5x
12 - 4 = 5x - 4x
8 = x
x = 8
Thus,
The equation represents the pages after x nights.
Wren:
12 + 4x
Jenni:
4 + 5x
After 8 nights Wren and Jenni will be on the samepage of the book.

any expressions equal to three would be equivalent to 1/2(6)
Answers
If 15% correspond to 100%
then 18% correspond to X%
We notice that both lines are in the following proportion:
(15) / (100%) = (18) / (X%)======> X%= (18 x 100%) / 15= 6/5 = 1.2 =120%
Answer:
Maxine is incorrect.
Step-by-step explanation:
18 - 15 = 3 3/15 = 0.2 0.2(100) = 20.
20% is the percent of increase. 120% would be the total of both combined. Since we are only looking for how much more, it would be 20%.
