We are given
piggy bank has nickels , dimes and quarters
Let's assume
number of nickels =n
every two nickels there are 3 dimes
so, number of dimes are


every two dimes that are 5 quarters there
so, number of quarters are


so, total number of coins = number of nickels + number of dimes +number of quarters
total number of coins =n+1.5n+3.75
there are 500 coins
so, we get

now, we can solve for n

divide both sides by 6.25
so, we get

number of dimes is 1.5n


number of quarters is 3.75n


so,
Number of nickels =80
Number of dimes =120
Number of quarters =300............Answer
Answer:
80+(15x)
Step-by-step explanation:
10 times 8=80
1.5 times 10=15
so she gets 80 dollars for the first 8 hours then for every extra hour she gets 15 dollars
Answer:

Step-by-step explanation:
<u><em>The complete question is</em></u>
Given the quadrilateral is a rectangle, if LO = 15x+19 and QN = 10x+2 find PN
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are congruent and bisect each other
so

substitute the given values

solve for x

Find the length of PN
Remember that
----> diagonals of rectangle are congruent

substitute the value of x

therefore
